Bug Description
I experience significant performance loss with ubuntu 8.10 alpha 3 with my Intel DG965WH based system and SVDO/ADD2 video card. Actually, the performance loss started with ubuntu 8.04.1; I upgraded to see if there was any performance gain with the new version. While "glxgears" produced values between 1580 fps and 1496 fps with ubuntu 7.04 and 7.10, respectively, now I can only achieve something like 445 fps with ubuntu 8.10 alpha 3. I get an error message when starting glxgears that "TTM" was not available and classic mode would be used. Similary, the flight simulator "flightgear" achieves frames rates of 1-2 fps only.
My suspicion is that some of the hardware acceleration features of the X3000 system are not being used, and I don't know how to activate them with the new xorg.conf structure and the underlying automatic configuration approach.
I would like to see the graphics performance go back to the values achieved in ubuntu 7.04 and 7.10.
Your help / comment is greatly appreciated.

[Update]
Intel upstream has been in a multi-year effort to rearchitect X and the Intel 2D and 3D driver to provide better performance. While this work is underway, people are seeing variations in performance levels from version to version, for a variety of reasons. There are probably multiple unrelated bugs being reported in the comments here.
It is important to note and remember that glxgears is *not* a benchmark tool. It simply measures how fast the driver writes images to the screen, whereas most 3D applications are limited by render speed, not merely blit speed. Instead use a 3D game (flightgear, tremulous, etc.) that has a real rendering workload to make comparisons.
If you're definitely seeing performance problems and are able to narrow it to a specific cause, please do not comment onto this bug report - it's too lengthy and rambling already, and your issue will just be lost in the noise. Instead, make a new report and please be as specific as possible with exact steps to reproduce and as much detail and logs as you can. See http://

- Working xorg.conf for GMA965 chipsets under hardy 4.1 or intrepid k/ubuntu. - Valid Edit (2.4 KiB, text/plain)
I have now found a workaround for the issue.
I think it basically is to do with the upgrade from XAA to EXA acceleration.
EXA appears not be working with the Intel GMA 965 (GM) chipset (including the Intel X3100).
Upon editing my xorg.conf file to add references to XAA I now have better performance, and am able to use KDE4 desktop effects.
In particular, under Section Device, I added:
Option "XaaNoPixmapCache"
Option "XAANoOffscreen
Option "DRI" "true"
Option "AccelMethod" "XAA"
and also
VideoRam 440320
Option "XvMCSurfaces" "6"
Option "May_Need_
but not sure if these last three items are necessary.
Störm Poorun (subs-olan) wrote : | #5 |
Also, remove (or comment-out) any lines in your xorg.conf file referring to EXA, if you have them!
Störm Poorun (subs-olan) wrote : | #6 |
And one more thing, I'm not sure it's essential, but it may be wise to ensure that you specify the driver as 'intel' in your Device Section.
i.e.
Section "Device"
Identifier "Configured Video Device"
Driver "intel"

Störm,
I have tested your suggestion, but I don't see any improvement in the graphics performance. I restarted the X server with the changes to xorg.conf as you suggested, and glxgears still produces no more than about 420 fps. I can confirm, however, that according to the log output produced, i.e. Xorg.0.log, the acceleration switched back to XAA based acceleration.

59.xxyy frames per second looks like an indication of vsync is being used.
But I also find my X3100 performance too low.
Do you guys with X3100 have problems using Celestia? Here I get bad performance, missing textures and other weird artifacts.
unggnu (unggnu) wrote : | #14 |
I can confirm the 59.xx frames problem with i915 and i965. Looks pretty much like vsync which wouldn't be so bad.
Btw. textured video seems to be activated per default again but it doesn't seem to so slow but I haven't made so much tests.
I can confirm the flickering too on my laptop with i915 hardware. I965 doesn't seem to be affected.
Roberto Cássio Jr. (rcsdnj) wrote : | #15 |
I'd like to point that, even if this 59.* frame rate is due to vsync, it doesn't behave nice (like if it was vsynced). Tearing is still there.

Is there any hope the performance will ever go back up to where it was in ubuntu 7.10?

I have an Inspiron 1525 notebook with GM965/GL960 Integrated Graphics Controller. In Hardy it worked flawlessly. I upgraded to Intrepid after it was released and I have my Ubuntu fully updated. Still, I have this problem. If I run glxgears and move the window it leaves garbage on the screen (seems like glxgears renders on top of compiz, which I have enabled). Also OpenGL screensavers doesn't seem to work either, sometimes they start, but something is wrong with them. I did not experienced a total X lock-up until now. Also OpenArena's screen is corrupted and the menu is invisible. Besides this normal desktop operations work OK, and all compiz effects are also OK. I have experienced a total system lock-up during a fullscreen video playback after about one hour of watching, only a hard switch-
@Marc Nieper-Wißkirchen: Google Earth is unusable, the screen gets all messed up, and the textures on the globe's surface doesn't show up, either.

I'm experiencing the same problems on a thinkpad with an Intel Mobile GM965/GL960.
I noticed two things:
1) GL-applications seem to work better (less flickering, less textures missing) when compiz is turned off (tested with glxgears and google earth)
2) There is no hardware acceleration available which explains the low framerates (do a 'glxinfo | grep direct' to check on your machine)

@Jan Girlich: I get "direct rendering: Yes", but I still experience low framerates for glxgrears.
I use Kwin, not compiz. After I turned off all effects, I see no more artifacts, however - with them on, I could see quite a bit in addition to the effects being absurdly slow. In particular, when I opened a new window, I just got interference pixels until the proper window showed up.
Marc Nieper-Wißkirchen (marc-nieper-wisskirchen) wrote : | #32 |
I also have "direct rendering: Yes" and nevertheless low framerates.
@Jan: How low are your framerates? Even lower than those of the rest of us?
Jan Girlich (vollkorn) wrote : | #33 |
Without compiz:
jan@jan-x61:~$ glxgears
2798 frames in 5.0 seconds = 559.539 FPS
2671 frames in 5.0 seconds = 533.488 FPS
2760 frames in 5.0 seconds = 550.889 FPS
With compiz:
jan@jan-x61:~$ glxgears
2293 frames in 5.0 seconds = 458.450 FPS
2360 frames in 5.0 seconds = 469.041 FPS
2300 frames in 5.0 seconds = 459.050 FPS
So the framerates are about the same.

That's interesting. My system, which claims to use hardware acceleration (direct rendering: Yes), doesn't seem to be much faster (~600 FPS) than yours, which claims not to use hardware acceleration. So is the 3D acceleration of the GM965 of any use in Intrepid???

I don't have an Intel graphics chipset, but I find 3D in Intrepid is considerably slower with an nvidia chipset as well - in Hardy with compiz on, I get close to 5000 fps, but in Intrepid with compiz on I get either 4200 fps with the older 173.14.12 driver or 3000 fps with the new 177.80 driver (40% slower!). With compiz off both Hardy and Intrepid can manage around 5800 fps.
So maybe this bug also has something to do with compiz?

The problem is not with compiz, i think, because I use KDE, and Kwin effects, not compiz.

On my system (intel X3100/ubuntu 8.10) compiz works just fine until I start an opengl application (such as paraview). Then, the icons in the task switcher (alt+tab) are distorted, and also the frame around window previews (the preview you get when the mouse is over the task button) is scrambled, and probably some other things as well. Reloading compiz using the fusion-icon solves this issue. This was not a problem on 8.04. When I figured that it was a opengl/compiz flaw, I wanted to have xsever-xgl since on 8.04 it was pretty good at compiz/opengl at the same time (at the cost of performance loss, especially with fullscreen movies), but it is not in the repo's anymore..

I just upgraded to 8.10 and noticed everything is slower. I suspect it's the same issue with video driver because apps get redrawn slowly when I switch windows or workspaces. I'm not using Compiz because texture size bug is still not patched and GL_MAX_TEXTURE_SIZE = 2048 which won't work with my 2x 24" monitors.

Hi Dan,
Thanks for reporting this bug. I can't see anything from the novell.com link above, (just get prompted for a username and password), so could you share some details with me?
Specifically, if I were to attempt reproduce this bug, how would I know if were seeing it or not?
I'm guessing that the x86_64 piece might be relevant, and the kernel version is likely very significant. Here's a review of some of the details, (with the actual component versions from the logs rather than the xorg 7.4 numbers):
Architecture: x86_64
Kernel: 2.6.27.4
libdrm: 2.4.0
X server: 1.5.2
xf86-video-intel: 2.4.97
(All OpenSUSE packages of course.)
I'll see if I can get a system running something close to that soon, (though I'll be out of town for the next week).

Hi Carl,
The issue I'm seeing with EXA is that window drawing (2d) performance is very slow to the point where it feels like I'm using a very old system with a vesa driver. Minimizing, maximizing, or dragging windows around is laggy. Not unusable slow, but probably a good 10 times slower than with XAA. I don't have the desktop effects enabled (although I believe AIGLX is turned on). I don't know of a good way to benchmark window drawing performance but I would be happy to provide some hard numbers instead of my subjective "goes slow" statement if there's a better way. There was a Video BIOS update for the T61
(http://
that I installed to see if it helped but it didn't. From
the release notes:
"(Fix) Intel GM965 Video BIOS was updated to v1668 to fix a blue screen error
issue on the Windows Vista."
Just let me know what additional information I can provide.
Thanks,
Dan

Thanks. There's a little more detail in there which is useful.
What we really want to figure out next is what operation is being asked
for here, which gets us to...
> I don't have
> the desktop effects enabled (although I believe AIGLX is turned on).
The real question here is whether or not there's a compositing manager
running. One some distributions, (such as Fedora, I believe), by default
there's no compositing manager running, (just metacity without its
builting compositing support), and then if you turn on "desktop effects"
it runs compiz. That may or may not be the same with OpenSUSE.
But better than just knowing "yes, there's a compositing manager
running" would be to find a benchmark score that actually changes in a
manner that correlates with the behavior you are seeing.
For example, if the slow operation here is straight blitting, (window
copying without blending), then you could run something like:
x11perf -copypixwin500
or so under both XAA and EXA to see if the scores change in a manner
similar to your bug. When you find an x11perf test case that changes
with XAA and EXA then we've hit the jackpot and debugging gets *much*
easier from there.
I'm suspecting that compositing is actually happening here, not just
copying. In old versions of x11perf there weren't any compositing tests.
If you've got a sufficiently new x11perf then you can do something like:
x11perf -comppixwin500
I'm not 100% sure that that test is doing something entirely useful, (it
does seem to call the right blending functions but with apparently no
alpha channels).
Anyway, any details you might be able to provide would be great.

Those are helpful details with respect to versions, etc.
Do you or anyone else here happen to know if OpenSUSE 11.1 Beta4 is using a compositing manager by default? (That is, without enabling "desktop effects".)

I've been able to find a few specific tests that are significantly faster under XAA than under EXA. With XAA I have:

With EXA I have :
2000 reps @ 4.6828 msec ( 214.0/sec): 500x500 stippled rectangle (8x8 stipple)
There's a lot of places where EXA is faster than XAA as well but I'll upload my full results from each. I had a system crash during the EXA test (unrelated to video) so I don't have full results but hopefully this sheds some light.

Carl, I'm not sure if a compositing manager is started by default on openSUSE 11.1 Beta4.
AFAIK Gnome uses compiz if desktop effects have been enabled. In KDE4 the compositing manager is integrated (into kwin?).
There were some discussions to enable desktop effects by default for a whitelist of drivers depending on the graphics chip in use. It might be
enabled for 965GM by default.
Anyway, Dan said in the Novell Bugzilla report and in this one as well that he has desktop effects not enabled.
BTW, I noticed that Composite extension has not been enabled at all through
xorg.conf.
Section "Extensions"
Option "Composite" "on"
EndSection
is missing in Dan's xorg.conf. Have this extension enabled is not the default
of xorg-server 1.5.2.

When there's a problem without a compositing manager, does running something like xcompmgr -a improve things with EXA? Without a compositing manager, some of the x11perf tests with very low numbers involve read-modify-write cycles to uncached memory...

I compared the log-files from both OS-es.
The several Xorg driver and module versions, reported by Xorg.0.log are the same. EXA is used in both cases.
Looking at glxinfo results, the main differences are in Mesa OpenGL Renderer and OpenGL version strings, and GLX extensions.
In neither cases does does xorg.conf contain any special device options, so it is not included in the tarball.

Volker Hoffmann (vhoffmann) wrote : | #67 |
I have tried downgrading to Intel driver in Intrepid by (forcibly) replacing it with the Hardy package.
If you do this, X will refuse to start because the older driver was compiled against a different version of X and depends on certain ABI calls that have since been removed; consequently X won't start.
I guess one could compile the old driver against the new X and hence backport it if one is really interested.

Screenshot of graphics corruption
One other weird issue I have when using EXA but not XAA is that I'll get graphical corruption in my Groupwise client text. This is a java application and I'm currently using the following JRE:
java version "1.6.0"
Java(TM) SE Runtime Environment (build pxa6460sr2-
IBM J9 VM (build 2.4, J2RE 1.6.0 IBM J9 2.4 Linux amd64-64 jvmxa6460-
J9VM - 20080816_
JIT - r9_20080721_
GC - 20080724_AA)
JCL - 20080808_02
Scrolling around in the app or clicking anywhere probably forces a screen refresh which clears it up but eventually (without user interaction) it will come back.

I have the same problem with poor performance here. I just tested the 8.04 and 8.10 live cds (even the 64bit ones) and the result in glxgears is the same. In 8.04 I have over 1000 fps in glxgears, in 8.10 it drops to around 220 fps, sometimes even worse. Everything in compiz is very choppy. I tried the XAA acceleration method, but it's not much of a gain (with EXA, it is so bad that you can't really think of using compiz).
It's really annoying to work with such low fps, so if I can help with any logs, just ask. I looked myself into them and tried to compare them with the ones in here, but couldn't find anything similar.

My conclusions:
1. If your direct rendering as a user is not working according to glxinfo check if it works with compiz disabled. And vice versa.
2. There is no significant difference in performance when run with user previliges or root previliges.

Mike, I can confirm the 50 fps glxgears: just tried openSUSE 11.1 beta5 LiveCD, getting similar results.
Of course glxgears is not a good performance guide but in my case, the relative framerate changes in glxgears are correlated to the relative framerate changes in openarena timedemo when trying different versions of ubuntu with different xorg-server, intel-driver, etc.

50fps on glxgears isn't an indication of vsync enabled (maybe working
incorrectly, since usual refresh rates are more likely to be 60, 75, 85
fps)?
Do you get tearing on this 50fps setup? If not, maybe this is an
evolution... just wondering.

Something else I just noticed today is that Cheese no longer works with my webcam. Not sure if it's related, but again this is something that worked fine in Hardy. The driver is in there, but there is no image.
Juan Garcia (juanantonio-garcia-01) wrote : | #109 |
the designer: get the source from here http://
Uncompress it and go to the folder where you uncompressed, and just go through the standard sequence of commands:
#./configure
(You will be informed about the dev packages missing, just install them with adept manager. Just run ./configure till you get no complaints)
# make
# sudo make install
The drivers will be installed in: /usr/local/
Which in Ubuntu is the wrong place (probably it can be configured with some option in the configure script)
Type:
# grep -i intel_drv /var/log/Xorg.0.log
This command will return the right location of the intel driver in your system.
Just make a backup copy of the intel_drv.so and overwrite it with the new one in /usr/local/
You need to reboot your system (or at least Xorg) after this.
Anyway still the issue is there when you have the desktop effects enabled and it is slower than Hardy by around a 20%.

Dan,
Thanks for posting the results from this performance testing. There's definitely something interesting to see in the results from the 4 variants of the copy tests (shown below for the 10x10 tests and the 500x500 tests).
For most of the EXA tests the performance is basically unchanged when changing from 10x10 to 500x500. That suggests that there is good GPU acceleration happening. Contrast that with the XAA results where performance generally falls dramatically from 10x10 to 500x500 suggesting that the CPU is getting involved on a per-pixel basis.
The big exception is the pixmap to pixmap test where not only does EXA get dramatically slower from 10x10 to 500x500, but it's also from 2x to 14x slower than XAA for this case. So there's obviously something quite broken there, (perhaps migration for a fallback).
If you've got a recent xf86-video-intel driver (from git) then you can turn on the following option (in the device section of your xorg.conf file):
Option "FallbackDebug" "true"
and then check your Xorg.#.log file to see if there are fallbacks that correspond to the slow behavior you're seeing.

I used to have flicker problems on Hardy when I run GE with Compiz, so I keep my compiz turned off. Though I tested to see if it was working and I don't seem to have problems with wobbly windows etc. They seem to work OK. Performance difference with/without DRI on Hardy was 6000/4000 frames with GLX gears and that made a huge difference in GE.
Just for the record, afaik GE needs SSE2 as well, and it is supported on the laptop.

In general the performance is OK, but seems like something went wrong with the 3D drivers... I hope the "buffer underrun" message in Xorg.log or the date difference in MESA drivers can give someone an idea to fix this.

I can confirm that the frame rate goes up in Intrepid Ibex (Gutsy Gibbon untested) when glxgears is behind another window or minimized.

The other issue I have is that when I boot the machine from cold, or restart it, X will NOT load. If flashes a black screen, and then garbage, and then black, and then black. I see the hard drive light blinking so I know its actually loading in the background. I can press ctrl-alt-backspace, and then ctrl-alt-delete to get the machine restarted. I have to choose "Recovery Mode" in Grub, then choose the "Resume" option. Doing it this way, X will load fine, but performance is terrible.. but it's all I got!
I can reproduce this every time I boot from cold, or restart the computer.

This more sounds like you are not using the Intel driver. When you have
booted in recovery mode, can you please check your X.org log and see

I got some details wrong above.
We do expect substantial slowdown between the 10x10 and 500x500 tests. And in fact, the original numbers reported here are basically physically impossible. The expected results are about 1000 operations per second for the 500x500 case (based on available memory bandwidth) and about 125000 to 250000 operations per second for the 10x10 case (limited this time by the maximum rate of command submission).
So something went wrong in testing that you saw such impossibly large numbers.

Recent Intel driver and the latest xorg (not yet released) and 2.6.28 kernel has new memory management GEM which address slow performance for intel graphics. It is not bug in ubuntu 8.04 and 8.10.
7.xx ubuntu is fast because there were intel driver with TTM memory management which was droped by intel (in flavour of GEM).
You have to wait for ubuntu 9.xx (I hope there will be new intel driver) or you have to compile xorg/kernel/intel by your self which is not an option for usual users. Or go back to 7.xx ubuntu.
I've 400 fps in ubuntu 8.04 and 1150fps in ubuntu 8.04 with new xorg/kernel/intel driver. There are still major 2D performance issues when compositing and others have reported slow 2D - https:/

Things started going wrong with the 3D acceleration only after Intrepid update.
Also I wanted to test xf86-video-intel 2.5 from git. However I am having a problem with "libdrm.la" when I try to "make". It seems like libdrm.la was removed from libdrm package after version 2.3.0-1. Does anyone know how to work around that problem?

The GEM bits are going to the 2.6.28 kernel NOW, and they will be stable when that kernel version become the stale one.

Kernel 2.6.28 is not stable yet in kernel.org:

And I guess that Ubuntu 8.10 wiill only come with 2.6.27 kernels packages.
To test GEM I presume that one should compile some 2.6.28 on his/her own and
try it out. This is quite time consuming, specially guessing the correct
config settings for the kernel compilation. (Or is it there a tool to port
the ubuntu (or array.org for eees) kernel's config to version 2.6.28?)
Then you can download and install the latest unstable GEM drivers from intel

I've done some testing with OpenSUSE 11.1 Beta5 (the KDE4 LiveCD) and identified some performance issues. I haven't done comparisons with XAA yet, but instead compared performance against my standard development build. This currently consists of:
Linux 2.6.28-rc4 (from git://git.
X server 1.5.99.1 (recent master)
xf86-video-intel 2.4.97 (recent master)
For testing I took x11perf with a selected set of tests (eliminating all of the uninteresting core rendering tests such as stippled fills, wide lines, ellipses, and arcs). I ran these tests against my "master" builds and then the same tests on the same hardware after booting the OpenSUSE live CD.
Finally, I manually scanned the results looking for cases where the performance differed by 2x or more. Below is a sorted list of the differences, showing the "master" performance followed by the OpenSUSE performance for each test. Also, for each test the relative performance is quantified (where "slowdown" means that the OpenSUSE performance is slower than the "master" performance---note that in two cases there is actually a speedup instead).
The next step would be to do profiling of some of the slowest tests, or perhaps to switch out one or more components to see what's contributing to the performance difference. Any contribution to those efforts from anyone would be most appreciated---as would any verification of these test results, or similar testing with XAA.
The copywinwin test is likely the most fundamental. And it perhaps is at the root of several of the other slowdowns.
Here's an x11perf command line that can be used to quickly obtain results for just these tests that seem interesting:
x11perf -repeat 2 \
-aatrap1 -aatrap10 -aatrap2x1 -aatrap2x10 \
-aa10text -aa24text -rgb10text -rgb24text \
-scroll10 -scroll100 \

-shmput10 -shmput100 \
-getimage100 -getimage500 \
-compwinwin10 -compwinwin100 \
-comppixwin10 -comppixwin100
And here are the results I obtained:
-aatrap2x1: 316000.0/sec
-putimage10: 126000.0/sec
-copywinwin10: 137000.0/sec

Just adding that TTM was never used as a memory manager pre-hardy. Other than that, we are in the middle of migrating the intel driver to the GEM stack. However, it seems that non-GEM performance has taken a *huge* hit. 2.5.1 in jaunty has poor glxgears (350 fps) and poor openarena (1-3fps) scores. There is definitely a performance regression somewhere in here.
Makes me wonder if enabling GEM will only make the performance go back to 7.04 or 7.10 days.

This bug seems to affect also intel 945 chipset. On a aspire one I had a drop from around 1000fps in hardy to 300-400 in Intrepid. Adding the tunning below to /etc/rc.local allowed to get some fps back, up to 630 on average. But on a netbook, every lost fps can be seen to affect overall performance.

pierrestz (coolos) wrote : | #165 |
I think the performance regression of intel driver is due to the lost of the 'INTEL_BATCH' variable.
This variable can be set in Hardy to get a huge performance boost in 3D (can be seen in glxgears, but also openarena, compizeffects...)
for example in Hardy, compare the output of :
glxgears
and
INTEL_BATCH=1 glxgears
i have +100% fps on i915 (1024*600 16bpp) : result 1480fps
This variable is not set by default on a Hardy install, but it is set when i launch compiz from a console.
The problem : this variable is no more used in intel driver (deprecated) so Intrepid can't benefit fom it. From what i understand (being far from an expert ;) ) we have to wait for GEM/TTM to get the same performance in the future...
If someone can recompile the intel driver sources used in Hardy, to make it work under intrepid, maybe we can get better results ?

This is interesting. How exactly do you force it to use the vesa driver ranther than the Intel driver since the xorg.conf file is no longer used in Intrepid? Back in day I would just change the ¨Driver¨ section to ¨vesa¨, but since this new Xorg doesn´t use the config file I´m not sure.

Most likely it's because Fedora backported GEM and TTM to their kernel for their ATI and Intel drivers.

Sorry, I meant GEM and KMS. Also, it's disappointing that GEM only restores performance (measured by glxgears) to their original values before. I had hoped for ~50% increase in perf to match Intel's Windows driver. Maybe the new hardware just isn't optimized yet.

Correct me if I am wrong but...
Can you do GoogleEarth, Compiz, glxgears, or any 3D in general with the VESA mode?
I think you can't, so giving up 3D acceleration because of a crapy driver is not the solution (not for me at least)
I prefer to have compiz more or less working and low glxgears FPS while I investigate why Fedora 10 hasn't got this problems.
I downloaded Fedora 10 yesterday and plan to test the live CD soon on my eee 901 (via a Unetbootin made USB), then I'll publish here my impressions.

I have installed Fedora, reporting this for comparison purposes (I intend to reinstall Ubuntu when this bug is fixed!)
1) Performance in 3d games is far better -- 50fps in bzflag with all options turned on, as opposed to 15-20 at lower quality settings in Intrepid.
But!
2) Some users report hanging X on startup (https:/

It is interesting that all people here are reporting all the same again and again altough everything was said.
Fedora 10 is based on unstable GEM patches and intel driver (and probably master branches of mesa/xorg) . GEM is too new and it takes some time that intel stabilize it and do all optimizations.
Ubuntu 8.x will probably never have official accelerated driver because it depends on new Kernel and new xorg/mesa (my opinion). There is NO way to configure/turn on things to make it faster until you recompile new kernel/xorg/mesa and intel driver for yourself.
The situation is a little bit frustrating but thats the reality. Wait for new official stable kernel/
If anyone has some new information, post it. Complaining and repeating all the same does not makes things faster. Thats my opinion :)

As described in comment #26, the performance problems appear to exist in OpenSUSE 11.1 Beta5 but not in the xf86-video-intel code which is currently a release candidate for the upcoming 2.6 release.
So whatever the bug is, it appears to be fixed in the current code.
Please feel free to reopen the bug if you do find that the performance problems persist even with the latest versions of the driver.

1029.463 fps !!! Thanks ART!!!
This is great, to get the ~1k fps again with intel 965GM and Ubuntu Intrepid:
1. I installed kernel 2.6.28rc6.
2. I added the following line to /etc/apt/
deb http://
3. Update some packages (e.g. xorg-video-intel).
4. Then I changed the previous line to use jaunty packages as:
deb http://
5. I updated some packages again (e.g. mesa, libdrm and othe packages).
6. Finally, I rebooted using the new kernel.
7. 1029.463 fps !!!
A note about UXA:
I have tried with UXA and got the same fps, however I could not see video files. Therefore, I am using EXA, actually I deleted the /etc/X11/xorg.conf and X server enables EXA by default.

I've tested your resolution in a Jaunty 9.04, with kernel
2.6.28-2-ub-generic in Jaunty repo (It's based on 2.6.28rc6, so I don't
think necessary to compile a 2.6.28rc6 myself)
After install mesa and drm-snapshot in the xorg-edgers repo, I got a higher
FPS, ~900. But after reboot, I cann't get into X. I got these errors:

I think maybe it's due to the incompatibility between Xserver and the

1.5.4). I'll wait for an official resolution.

Great news!
One thing. I am not using an Ubuntu stock kernel but Array.org provided one for and eee 901.
Does kcheck build a kernel from the configuration of the kernel you have (like array.org in my case)?
or does it do it from well-known distro kernel templates?
(Anyway I am giving it a try for sure!)

MPC's method works for me. I am currently running 64-bit Intrepid with a custom kernel ( 2.6.28-rc7 ). I only wish that I had found out about this method before spending hours of frustration compiling and testing things trying to find something that worked atleast halfway decently. Besides the kernel, I just installed all of the upgrades from xorg-edgers for intrepid and then I changed to jaunty and installed all of the upgrades from their. I didn't get doubled performance (atleast not according to glxgears, but that may be due to slower cpu) but performance did go from 400 to about 700 - and I can now play 3d games (nothing would run before).

JoseLVG: I suppose that kernelcheck use well-known distro kernel templates.
Biji: xorg edgers provides also 64 bit packages.
Instead of building the kernel it is possible to install kernel from jaunty and also works.

2. from the xorg-edgers ppa, install the mesa an required packages, and xserver-
3. restart X (before restarting it works, but with warning that GEM is not used, and no performance improvement)

I am in the same situation as many above: Dell Vostro 1310 with GM965 running Intrepid Ibex. It's a Core 2 Duo with 4GB of ram. The graphic performance is clearly incoherent to the hardware capabilities.
On Hardy, the performance was good, no slow scrolling issues and a (at least) 2 times higher FPS rate in many apps (including glxgears).
I see almost no improvement using all the Options in xorg.conf described here or in (many) other places. Glxgears always give me something around 250 to 400 fps which I consider to be very low. I have attached xorg.conf.
How does this situations work? Are we waiting for a fix from Intel or from the community? Is there a time schedule so we know how much more to wait? Are there beta fixes we can try? Where? Either way, will there be a new automatic update to Ibex that will fix this? Or is this something that will only be fixed in the next release of Ubuntu?

Effenberg, please re-read last several comments - it's possible to get ~ the same performance as it was in Hardy by upgrading kernel to 2.6.28-2 version from jaunty repository, MESA related packages and xserver-
In my case it help me to increase FPS from 550 to 1100 + google earth works much better (even comparing with Hardy), but some rendering glitches still remain.

Carl, do you think if we can point out which patch (or patches) that fixed the performance regression issue? Even some clues of how to find them, or our graphics driver in Novell's SLED11 has big problems in performance, especially for those hardware that can work very well on SLED10.

If I knew, I would be glad to share them. But sadly, I don't.
> Even some clues of how to find them,
First, identify which component (or combination of components) is causing the problem. The latest stuff that's working well is the for-review branch of anholt's kernel tree, the master branch of the xf86-video-intel driver and the master branch of the xserver repository. If a single component can be identified as the culprit, then it should be a simple matter of doing a bisect to find the specific commit(s) of interest.
But I can't guarantee that there's some simple commit that can be backported. The issue could depend on large infrastructural changes in the kernel that may not be feasible to put into whatever release is of interest here.

That's really an issue for Novell to address. We've identified that our latest code does not have this problem. Again, when our code is having problems, then we will be happy to put time into fixing them.

I lost array.org's wired and wireless network and lost the keyboard settings so I couldn't even check if a was running the proper intel driver and drm versions. GoogleEarth seemed a bit smother but all text were totaly lost so it was still unusable.
I totally discorage other eee users to try this if unsure. I guess we have to wait for Ubuntu's or array.orgs fixes.

It looks like you've never rebuild a personal kernel, all the modules must be rebuilt too ( like the Wifi driver, hotkeys driver etc... ) .
For the keyboard problem, I too have this issue but I've solved it by redefining my keyboard layout, and Tormond says it will be fixed in the 1.6 beta version of xorg-xserver-core .
About your FPS, that's very strange, I jumped from around 400 to 900 without any problems, which means a little more than doubled performance ! But you've got only 100FPS more, et that's very strange, perhaps you're using the wrong acceleration method ?

We'd like to forward your bug upstream, however upstream requires

To save you the effort of building the driver from source, we've built

So you have a couple options:
1. Download and test .debs for intrepid, from:

2. Download and test the Jaunty alpha-2 (or newer) Live CD,
(which includes a beta of the new xserver 1.6 as well).

If it's at all useful, I can also confirm that the debs from the edge testing repository have done nothing good, and actually have roughly halved my glxgears performance; it's now down from 350fps with the release drivers to 150fps. And, with any other redraws going on, such as Amarok's play window, glxgears performance is reduced a pitiful 30fps.

I have tested my system with Jaunty alpha-2 and the results are not very encouraging. The performance indication provided by glxgears dropped even further and is now in the 200 fps range, about half of what it was with ubuntu 8.10 final and way below what it was with ubuntu 7.04.
For the sake of clarity, I am using an Intel DG965WH board with the G965 chipset, which includes the X3000 graphics subsystem. Refering back to my initial bug report, I did run tests with FlightGear 1.9 under Windows recently. It can achieve frame rates around 25-30 fps. This indicates to me that the hardware setup in general is quite capable of executing the task at hand.I am not very familiar with your terminology of "moving a bug upstream", please let me know in more detail what action you expect me to take.

I have a netbook with an Intel Mobile 945GME Express video chipset, on which I run Kubuntu Intrepid. It's newish, like most netbooks, so I don't have data on its video performance in Feisty.

Is this user error, or has there been a considerable regression? Perhaps related to GEM being merged into the kernel? HAL takes care of configuration so my xorg.conf is basically empty. If UXA is default in the drivers from xorg-edgers, I guess that's why I used when I tried it. It's certainly EXA with Intrepid's.

Hi Dan,
While I do genuinely appreciate you reporting new issues, can you please do so in a new bug report? If we discuss multiple issues under a single bug report then actions like "closing bug as fixed" quickly become meaningless.

For this to work you need either older versions (xorg-7.3, xserver-1.4) or newer versions (xorg-7.5, xserver-1.6, linux-2.6.28). Hardy doesn't have older versions, newer versions of xorg and xserver are not released yet and they wouldn't get into hardy anyway (maybe through backports), they will get into jaunty probably (if I remember right it is scheduled after new xorg and gnome releases) but for now I wouldn't hope that anything will change soon. It was at least careless to include xorg-7.4 and xserver-1.5 in hardy when this intel issue is a widely known one.

Just as you said, kernel have been made a big change. I ever tried to backport the kernel (GEM), however it is not acceptable by Novel, because it has touched other modules except drm, agp more deeply.
Now we can only check on 2d, 3d for verification.

Good god this bug has gotten far too long in the tooth. 213 comments!
I'll get into some good news and bad news regarding performance, but first some administrivia rantiness.
Okay, here's the deal. This bug report is turning into a mess of different performance-related bugs, and actually isn't useful in getting this problem -- everyone's problems are all intertwined together. Some people are seeing issues with -intel, but others are clearly having problems on the 3D side with mesa. Sadly some specific (perhaps solvable?) issues are getting lost in the noise and as such aren't going to get investigated, at least not here.
The problem is that the title describes a generic symptom, and everyone with a performance-related issue has piled on. This is a good lesson why it's important to file bugs with precise, specific titles. The poor original reporter is probably lost under a pile of replies! :-)
Honestly, I think the best thing to do here is to close this bug report and have people file separate bug reports. But from past experience I know we'll eventually end up with another generic titled "performance is bad" bug report with a gazillion comments and no clear path to a solution.
So... I may as well leave this one open and leave some explanations of how to file a proper performance bug report. Those who take the time to find and read this comment will learn how to file a NEW bug about their issue and include sufficient detail and precision to enable us to easily investigate it and report it upstream (or fix it in Ubuntu if there's a way for us to do that).
Okay, with that out of the way, let me get into the performance stuff. First let's dispense with the bad news: It is extremely unlikely performance problems are going to get fixed in Intrepid.
There's several reasons for this. First is that the issues are structural. A lot of pieces in X are in a multi-year process of being rearchitected to bring both a number of new features and to lay a foundation for much better performance. Unfortunately these changes can be pretty sizable, and inevitably bring some regression bugs - a risk not worth taking in a stable release.
Second, a lot of time the performance fixes require a pretty hefty amount of study and testing. Some of you may recall we had some pretty severe performance regressions in Hardy during development. It took a pretty focused amount of effort to dig in and figure out how to flip on and off various internal features to tune things up. Often a change that fixed one set of cards would cause problems on another set; so it took a lot of testing (including a lot of welcomed involvement from the community) to strike the right balance. The time investment for doing this tuning work is hard to understate.
Third, and sort of getting back to my original points, even if the above two problems didn't exist, the issues are not reported with sufficient specificity and detail to be able to begin investigation. But this is something you all can help with, and I'll explain how in a follow up.
Enough bad news, now for the good news. Looking forward, things are definitely getting better. In playing around with Jaunty Timo a...

How to Report an Intel Performance Problem
First, make a new bug. The easiest way, which will pull in a lot of useful logs and config files, is:
ubuntu-bug -p xserver-
Second, select a very precise title for the bug. If you use a generic title like "performance sucks" it will just attract others with unrelated performance issues to comment on and hijack your bug, which just wastes everyone's time, most especially your own!
Next, provide very specific steps to reproduce the issue. Reproduce the problem yourself several times (including after a fresh reboot) so you're certain it's just not some random quirk. When a developer or tester is able to easily reproduce your issue, it makes it immensely easier for them to figure out how to fix it, and to be certain that your issue is gone.
For performance bugs, a few other bits of data can be useful, including `glxinfo` and `xdpyinfo` output, and a video or photo (particularly if the perf issue is accompanied by graphics corruption or glitches.) See http://
Finally, vary your setup and see how many different ways you can or can't reproduce it. Try it with compiz on vs. off, or on a different version of Ubuntu, or a different distro with the same xserver/driver version, or on another computer also running Ubuntu but with different Intel graphics chips. Or try out some xorg.conf driver parameters listed in `man intel` to see how they influence things.
If you follow these guidelines, you'll stand a much better chance of getting your performance issue looked at. Be aware, though, that with performance issues Intel is mainly concerned with what is in their git tree; they may ask you to build and test their latest code, and if the issue doesn't exist there they'll consider the problem solved.

Bryce—
My apologies for adding to an already long bug, but I do have a comment regarding your last post. I'm hoping that you can help me decide where to start with new, more specific bug reports, but also I want to provide some perspective about why this is harder than it seems.
The behaviour reported with glxgears's low fps is not exclusive to glxgears; it just happens to be the best way I (and presumably many others) know of getting a reasonable framerate number that's consistent relative to other systems running the same hardware. Granted, it is not a good exhaustive test of video performance, but as a "do we have a problem here" benchmark, it seems to do a good job illustrating the dramatic difference between different software versions (especially since other 3D benchmarks seem to be basically unusable at this point, at least on my system).
This performance problem is not exclusive to glxgears reporting lower than expected framerates; it also occurs when playing a video with mplayer, or using a visualiser in amarok, or displaying pages in Firefox with lots of animation, or running a 2D or 3D DirectX application in wine, or.. well, basically anything to do with writing to the screen. Trying to run more than one application that updates the screen at regular intervals grinds things to a halt very very quickly. (For example, I can only watch videos in mplayer if Amarok has all of its windows closed. Even if Amarok's windows are in the background, or minimised, or if Amarok is paused and not doing anything, playback in mplayer will still be jerky until the windows are closed completely.)
It's challenging to split out the problem into different components in part because it is so pervasive throughout the system, which is why I think that we've ended up with this huge monolithic "performance is bad" bug. 2D performance is slow, 3D performance is slow... everything is just extremely, extremely slow, and anyone with an Intel video chipset is severely affected by this problem.
I would like to do whatever I can to form reasonable, reduced, and reproducible bug reports. I am just at a bit of a loss as to where to start because there's no specific place where I can go "this works OK, but this doesn't". Nothing works. It's all slow. Throw a stone and you'll hit something that isn't performing as it should. So, if you can tell me what you think would work well as a test report that can be sent upstream easily, let me know and I'll write it. I just personally feel a little overwhelmed with the amount of brokenness to try to start picking apart all the different issues and choosing the best one to report (and if I tried to report them all, I'd probably be here until next year).

What exactly do you need, if not glxgears then tell us what. There are plenty of people with intel cards that are willing to provide the input you need including me but at this point we need to know what.
The thing we all need to get at this point is its broke for all intel cards. Dont get mad because everyone with an intel card is reporting here because its broke. It's not their fault a release broke intel support. I see no point in starting multiple threads on this, as it will just turn out to be multiple threads saying the same thing this one is.

I also agree, but there is nothing we can do, this bug report is just a
place to complain.
Some time ago (probably a year ago), someone or a group of people at intel
driver development, decided that they will throw away legacy driver code
(that was performing without so much user complaints as the current
releases) while they rewrote it. They thought is was a good idea. They were
too much confident they would fix it quickly enough before everybody
noticed... but they were wrong.
They should have done as you allways do this things, that is:
1. You maintain the old stuff while you write the new driver.
2. When the new driver is stable (and currently IT ISN'T!) then you
change the defaults to point to the new driver and leave the old one as a
fallback.
3. Later, when the old stuff is no longer mainstream or obsolete and the
new stuff is rock-solid, then, and only then, you get rid of the old stuff
and leave the new code alone.
I know it is painful (as a developer I really know it is) and it may sound
old-fashion, but it is more practical in the end.
But they decided to take the risk, and as Murphy law states, "what could go
wrong went wrong". We may have drivers performing decently again in 2011 or
so, (by the time Google Chrome Linux will be delivered) in the meantime we
can just complain or... if you know graphics development, retro-backport the
old TTM code (or whatever it was called) in new kernel and distro
releases... it will probably take less time to do than fixing current GEM
drivers.

Bryce wasn't getting mad. His point is that a bug report's usefulness
increases the more succinctly it can be written. Personally, I suspect
that the engineers at Intel and X.org, and Ubuntu are aware of the
current state of things.
Considering the prevalence of Intel graphics hardware, it could hardly
be otherwise.
I also think Snover's reply was very on point. Like I said though, I
don't think it's going to be any surprise to any of the engineers
involved.
My plan is to wait until things kind of start working, (which I figure
will be around the release of the 9.04 beta (I will keep checking the
Alpha releases though), and file bug reports on what is still missing at
that time.

I just installed the intel driver avaible on the backports repositories and now looks everything is better. Before the update I got 370 FPS on glxgears and now I'm getting something aroung 700FPS

I'm adding a me too message here. I'm on openSUSE 11.1 on thinkpad x61s with GM965 and EXA is very slow. I'll attach lspci -nn output and video capture of window/workspace switching and stuff on EXA and XAA.

Can't attach videos here directly due to size limitations.
Video with EXA: http://
Video with XAA: http://
The videos are captured with a cheap webcam so the quality isn't stellar but is sufficient to demonstrate the performance regression with EXA. Feeling slow or fast sure is subjective but the difference is large enough and that level of slowness would be quite annoying for most people.
Thanks.

Just a small note from "yet another user" -- Dell E6500, for me EXA is way faster than XAA, according to:
x11perf -copypixwin500
In EXA I get ~1920 (frames?) per sec, when for XAA 200-300. However, from user POV I can only say, what is already been said -- (KDE3.5.10) moving windows, window-switching, scrolling, watching movies is very slow.

Wow!
Luciano: That is backports for Jaunty 9.04or just plain Ibex 8.10?
(I guess you need a 2.6.28 kernel anyway)
What it your chipset?
I wonder if my eee 901 with Intel GME 945 will benefit from this improvement
also.
Still 700FPS is less than half the 1500FPS this driver achieved in the "good
old TTM days", so I wonder how it is GEM an improvement or if there are
still many performance gains to come.

is the procedure to fail back if the new driver has issues? Just
remove the backports repo, and reinstall original

> I experience significant performance loss with ubuntu 8.10 alpha 3 with my Intel DG965WH based system and SVDO/ADD2 video card. Actually, the performance loss started with ubuntu 8.04.1; I upgraded to see if there was any performance gain with the new version. While "glxgears" produced values between 1580 fps and 1496 fps with ubuntu 7.04 and 7.10, respectively, now I can only achieve something like 445 fps with ubuntu 8.10 alpha 3. I get an error message when starting glxgears that "TTM" was not available and classic mode would be used. Similary, the flight simulator "flightgear" achieves frames rates of 1-2 fps only.

Well, this bug report shouldnt become a support forum but...
If you disable the backports, the installed package will still be a higher version, so updating shouldnt change it. I guess you have to disable the backports, uninstall the package, update your package list, and then reinstall the package, wich should show the version in the main repository...

There is an easier way to downgrade the package. Just use apt-get install <package>

I am curious which backports repository is being used, exactly, and what driver version is being installed, since I have always enabled the intrepid-backports repository and the latest offered driver version is still 2.4.1-1ubuntu10, which has horrendous performance, at least on Q45.

It's worst than before with Intrepid (kernel 2.6.27 and intel 2.4.1) : ~ 200 FPS
I think this laptop should get more than 1000 FPS ?
I hope I will get better perf with the final release of Jaunty and my DELL E6400 (Intel GMA 4500 MHD)

tictactoe, I believe those frame rates suggests that vsync is enabled,
limiting the rendering to the refresh rate of your screen. The same happens
here. Unfortunately, though, 3D and 2D graphics don't seem to be synced to
vblank, since I still notice tearing.
I'm using the same setup with you (Jaunty with latest updates), except that
my video card is a Intel X3100 on a Dell Inspiron 1525.

OK Roberto Cássio Jr,
indeed, I tried to run 'vblank_mode=0 glxgears' then here are the results :
4233 frames in 5.0 seconds = 846.448 FPS
4223 frames in 5.0 seconds = 844.406 FPS
4221 frames in 5.0 seconds = 844.062 FPS
4199 frames in 5.0 seconds = 839.759 FPS
4192 frames in 5.0 seconds = 838.397 FPS
4135 frames in 5.0 seconds = 826.932 FPS
It's pretty good enough !
So I am going to test it with Intrepid ...
Could someone explain us the risk if we setup vblank_mode=0 permanently with driconf utility ?

Richard, yes those bar charts indicate there is performance regressions, but that's nothing we don't already know. Unfortunately the author didn't gather Xorg.0.log, glxinfo, xdpyinfo, or other data which could help in investigating the problem.
For those of you looking at glxgears fps, you're going to get a rude shock pretty soon. You've heard that glxgears is not a benchmark. It measures the blitting speed of writing a pixmap to the graphics buffer. Well, video monitors display that data at a limited rate (your refresh rate in fact). Most monitors display at a rate of 60-100 Hz (essentially 60-100 fps). So when you see glxgears saying it is writing frames at 800 FPS, well probably 700 of those frames never even get to the monitor, and thus are just a waste of electricity. Cleverly, upstream is now synchronizing the blitting speed to the monitor's refresh rate, so that it writes only as fast as the monitor can display. So you should see your glxgears FPS values drop down to something nearly equaling your monitor refresh rate. ;-)

I believe that in the past, Bryce has stated that 3D applications that
report frame-rates will do. Such as Tux Racer. In order for this to be
useful though, you have to be careful to capture your system
configuration: XXorg.0.log, glxinfo, xdpyinfo,, etc.
Phoronix also has a test suite that does similar things.

The problem with this is that you started testing glxgears because, for

You end up with some idea of the performance loss when they say that Ubuntu
7.04 could make glxgears achieve 1500FPS and now it done only 50FPS.
The question now is, how are we going to know if the performance of later
versions is enhanced or not if we don't measure it with the same tools? Does
anyone have numbers FPS on Tremulous or some other 3D intensive app as far
as Ubuntu 7.04 so we can compare with 9.04 (without the vblank sync thing
that makes numbers up)?
(The vblank sync that reduces Jaunty FPS might be a clever thing for normal
use and energy-wise, but is it not very useful when comparing different
driver versions for performance)

To answer "the question":
You can't. And what Bryce was saying was, "You never really could".
The glxgears score was never anything more than a rough metric for 3D
performance.
The solution is to move to new tools, and test previous versions with
those new tools, and then test later versions with those same new tools.
(this is what Phoronix does). I do this regularly. I do this by
maintaining different distribution versions at the same time. I happen
to use USB Keys to do this, but others use multiple partitions on a
single (or multiple) hard drives.
I have 8.04, 8.10, 8.10 with backports, and 9.04 on different USB keys
and test them periodically (when I have the time).
Its a bit of a pain, but I feel it is a way I can contribute.

About 2 months ago I was able to get the same performance as it was in Hardy by the following steps:

Today I've decided (I blame myself for that) to upgrade from xorg-edgers ppa and hope to get more stable driver and some rendering issues fixed, but unexpectedly got 45% regression:
glxgears: 1100fps -> 600fps
Planet Penguin Racer (ppracer): 40fps -> 22fps on 1440x900x32
So since I'm running on GEM-enabled kernel/
What exactly doesn't allow to keep performance at least on xserver-
Alter attempt to upgrade video-related packages to Jaunty versions things become more horrible:
glxgears: 600fps -> 50fps
I even didn't try to run ppracer, since regression in compiz performance was eye-sensible (I had to wait 5-7 sec to switch between windows via Ring/Shift Switcher plugins). Maybe it's due to turned on/off vblank_mode, but I don't know how to change it globally for all programs, including compiz.
PS.
I can't downgrade to xserver-

GEM is not used by intel drivers by default yes. As for now, it need to be enabled manually by adding line
Option "AccelMethod" "UXA"
to the device section of xorg.conf. It does not work perfectly yet, but you'll get reasonable performance (about 400 fps on glxgears) and working DRI2. There are some painful bugs with it (ctrl-alt-f* console does not work, and suspend/hibernate is broken, plus some minor problems with compiz), but it is better (IMHO) than jaunty EXA acceleration (50 fps, no suspend/hibernate, no DRI2) and there is still some work going, so the things will be improving. There is some kernel work going as well, so 2.6.29 kernel should work better with intel video.
There are major architecture changes going within a whole graphics system, so yes, things are broken. Hope this period of chaos is moving to its end :)

I had many many issues with this intel gm965/gl960 video card before (with ubuntu 8.04 and 8.10)
*It didn't support opengl 2.1
*lot of graphics errors on it's interface
*Google earth worked really bad, windows "collapsed" and things strange
With ubuntu 9.04 now I can work with opengl 2.1 but in it's default installation, it still had error 2 and 3 and also I experienced some performance issues.
With it's default installation glxgears gives me only 60 FPS in my laptop (Too bad).
After add Option "AccelMethod" "UXA" in my xorg.conf file glxgears starts working arround 400 FPS (more than 4 times improved the speed) and all errors before are fixed.
I don't know exactly why it happens, but when I added Option "AccelMethod" "UXA" to my xorg.conf everything seems to be working fine and google earth works great!
Is it a fix for this issue or just a work arround?

I'm having this problem also on an eee PC 1000 with Intel 945GME graphics adapter.
On Intrepid, my glxgears score was around 650 - 750. On Hardy, it could get as high as 1350. On Jaunty, the highest I can get is about 250, and that's with UXA enabled - with EXA, it topped out around 80.
Sander Smid (s-smid) wrote : | #302 |
I recently upgraded to 9.04 due the intel driver issues. When I run glxgears I get pretty okay FPS (420-480) when using UXA. Google Earth also works pretty well!
But there is a downside, I haven't been able to play any openGL game. They're all complaining that they can't load the OpenGL subsystem or that the X11 driver is not configured with OpenGL (something along those lines).
I tried OpenArena, Warzone2100, Chromium and PlanetPinguinRacer.
It would be cool to actually use the 3D capabilities of the card ^_^

I see the same problems, on Ubuntu as well as Fedora systems (which I use more frequently).
I saw some regression with Intel-2.5 and Fedora9, but it went really bad when switching to Intel-2.6.1 - I had best 2D performance with Intel-2.4, but OpenGL has always been 3x slower than on Windows.
How can they release a driver of that quality as stable? Are quarterly results really that important?
The consequence is a lot of people are receiving that broken stuff marked as "stable" by using stable distributions.
unggnu (unggnu) wrote : | #307 |
Just read http://
I guess it is because the Intel devs don't care. They don't use their own driver without patches or need no functions except of 2D to write code or just use another card/driver.
But of course it is not only an Intel problem. The whole Xorg development is a little bit weird. The don't really have a stable tree imho and push new "features" with every release which breaks something else. I guess devs like more to add new features instead of fixing bugs especially if they do it for fun. That's why you can't really ship Xorg without tons of patches.
And last but not least they live in the future. They seem to see Linux as a long term investment which doesn't need to work right now but needs to blow you away with later releases.
The only problem is that nearly no normal user cares what is under the hood as long as it does the job.

ok ok ok... it is going to sound really weird... look what I did...
I was getting really bad fps on glxgears, around 150fps... I wasted all day long trying to figure out how to fix it. I tried to install some new driver... the intel 2.5 and the fps got even worst, around 70fps.
So I tried to compile a brand new kernel 2.6.28.7, no success, also add the repository deb http://
when I was almost giving up, I tried to run the glxgears using: sudo glxgears and I got:
3733 frames in 5.0 seconds = 746.500 FPS
Ok, it not perfect, but comparing with 150fps, it is awesome. So I figured out that it could be a problem with the user. I went toe the users settings clicked on my user -> properties -> user privileges tab and I found a check box that says capture video from tv and webcam and use 3d acceleration. It was unchecked, so I just checked, log off and log on again, finally everything was working again. My screen savers, 3d games, scroll down on the web browser... it was awesome...
My computer specifications are attached. I'm using linux mint 6, but I'm pretty sure it is going to work on ubuntu too since both distributions are the same thing.

Bryce, to reflect your comments, I tested with flightgear and got frame rates between 15 and 23 fps depending on the scenary with the on-board graphics subsystem, i.e. the X3000 graphics processor. This is a significant improvement over the 1-2 fps frame rate seen previously.
For those testing with glxgears, my figures are back to around 1350 frames per second. The Xorg.log file states that EXA acceleration method is being used.
It seems that all the development work has finally been converging, thank you. I have attached the xorg.log file for your reference.

JoseLVG, are you using UXA acceleration? It is not enabled by default, you need to enable it manually by editing your xorg.conf (add
Option "AccelMethod" "UXA"
to the Device section of the xorg.conf).. With UXA your rendering problems should go away, but there is some amount of instability (that's why UXA is not used by default) and some little colour corruption as well. But you'll definitely need to give it a try.

Yes, they are changing the driver architecture - for the better. The problem is not with the drivers, but with distributions that package drivers, that are known not to work, without any alternative. Unfortunately every newer Ubuntu release seems less stable - super new suff included, but no one seems to care if the new stuff works.
Actually with intel driver 2.6.3, xorg 1.5.3 and linux 2.6.28 it performs well (with UXA) without hangups or something (compiled from source using gentoo ebuilds). I think that for full performance you should have xorg 1.6 (already released) and linux 2.6.29. I'm curious if they will package working xorg(+gem enabled linux) set for jaunty...

So I was reading this other bug (https:/

Well, that's what I did, and now compiz is very smooth and videos are not tearing anymore.
I did have a problem initially with VLC crashing when I clicked on any video file, but that was resolved after I changed the default video output to "X11 video output" in VLC's preferences.

The patch you are referring to does not disable GEM support, it only provides an option to turn it on or off at build time.

There are many who have that chipset. Some of them have reported

I would guess that for issues related to performance, the issues would

Note to eee pc users.
From what I've gathered, the intel driver now defaults to the EXA acceleration method which relies on the GEM memory manager. That should be fine and dandy however note that GEM is not part of the 2.6.27 kernel. So if by any chance you got your kernel from array.org and did not upgraded to 2.6.28 (from stock ubuntu), beside having an awful fps in most 3d apps, glxgears will tell you that it cannot use GEM and this means: switch to 2.6.28, your problems will be solved.

When I try to enable UXA, startx just freezes during startup.
I have also noticed, when I run glxgears, it says "Failed to initialize
GEM." Could this because I am using the 2.6.28 *server* version of the
kernel?

- GoogleEarth crash due to libssl 0.9.8 error (couldn't test performance)
- Planetpenguin racer: not very smooth 3-4 fps at 1024x600
- Tremulous didn't start either. (Maybe because testing jaunty on a

Thank you everyone who has contributed towards analyzing this bug for Jaunty. As many of you know, the Intel performance issues were not completely fixed for the Jaunty release, and I understand you are probably as frustrated as I am that it remains an issue for so many people. To those who have remained patient through this process, it is especially appreciated.
For the background behind why all this regression happened to begin with, I'd best refer you to Keith Packard himself (you may want to skip down to the "Pick One From Each Column" section, if you're not so interested in the technical stuff):
http://
It is unfortunate that Jaunty (and Intrepid, to a lesser degree) hit in the midst of this major rearchitecturing work, and suffered the consequences as a result.
One thing that is important to note is that not everyone sees the performance regression. Some have no problem whatsoever. Some see it only with compiz, and are fine sticking with 2D. Some see a slight regression but not so bad that it affects their workflow. This is not to trivialize the importance of having good performance with compiz (since we ship it on by default). As well, there are a sizable number of people who have significant performance problems both with 2D and 3D.
Given all the construction work being done upstream, the obvious question is why not to keep Ubuntu to an older, more stable version of the -intel driver such as 2.4 or 2.2. There are four reasons. First, it would undo fixes that were gained in 2.6 to bugs that were even worse than this performance problem. Second, some newer Intel hardware was enabled in 2.6, which would be lost if we moved to an older driver. Third, it would inhibit our ability to work with upstream to gain real fixes to the problem. And fourth, it is the wrong thing to do.
The right thing to do is to figure out what causes the problem, and fix it, and that is what many of us have been quietly working on the past couple months.
Let me explain what we have done to date, the current status, and the plan going forward.
In our testing, we've uncovered a lot of different ways to work around the problem. Sadly, there is no single workaround which solves the issue for everyone across the board. In some cases there has been sufficient consistency (such as a workaround that worked for particular families of chipsets) that we were able to roll out the change. In most cases, however, our testing found the workaround only seemed to solve the problem for some cases, and caused new problems (corruption, freezes, crashes...) for other cases randomly.
I generally consider stability to be higher up on the priority list than performance, so where we have an option that would give performance at the expense of stability I've opted to pass it by. Because the driver seems to be so sensitive to changes, we're being very deliberate in doing thorough testing; last thing we want is to rush some change out that causes more damage than it solves.
However, since these workarounds do in fact help people in some cases, I've capturing them in the Ubuntu-X wiki. My feeling is that even if...

Cheers for the update Bryce, I'm sure, even if the tone is heated at times everyone appreciates that someone, somewhere, is at least working on it !
I worry, however, about two things
a) the information about how to fix any issues wasn't included in the release notes. To me, it felt like Ubuntu was ignoring the problem, or worse trying to hide it.
b) any changes are so major (new kernel rev., for instance) that they won't ever be back ported into 9.04 from 9.10
For the record, I would prefer newer hardware plain didn't work till post-9.04 than saddle 'a sizable number' of existing users with a horribly bad (but working as you same) system... at least you can just say 'the latest Intel FooBar cards are not supported yet (and weren't in any previous version either)' and it's all very clear what is going on.

Currently the plan is to identify the specific kernel patches from the new kernel version that are felt to help the performance issue, and backport just those fixes. Whether this can be done without causing side effects remains to be seen in testing.

In the future, I hope we'll have your help in drafting release note
entries for remaining X issues in Ubuntu. For many developers, the
final weeks of the release are a mess of bugs and making the release
notes complete often falls to a secondary task, so having people who can
devote attention to them can make a big difference.
James Strother (jstrother9109) wrote : | #350 |
Bryce,
Thanks for the update, very informative. You mentioned in your post several reasons for not reverting to an older, more stable version of the -intel driver. And I agree that this would probably be counter-productive, in my experience the -intel driver has never really been stable on older chipsets. So my guess is that people would still be highly unsatisfied with the driver quality, the only difference would be that the bug reports would be against an old version and would no longer useful.
But, have you considered supplying a package with an older version of xserver that could run the i810 driver? Please note that I am not suggesting that Ubuntu rollback its xserver, just that it supply something like a xserver-xorg-legacy package that could replace the default xserver with an older version (one that supported i810) for users with older intel chipsets. Perhaps a little installation magic could pick the legacy driver depending on the detected hardware. I know that this is an ugly solution, and I recognize that simply fixing the bugs in the -intel driver is a more elegant approach. But, it has been over a year since Ubuntu stopped working properly on these chipsets. The most recent driver has rendered my system (and many others) completely and utterly unusable. And in all likelihood it will take many many more months before the regressions introduced by the -intel driver start to be pared down You asked for patience, but I think that the community has already been very patient. I think the most important thing at this point is to get things working again. And, ugly as it may be, this would restore basic functionality to many of the above users instantaneously (I just installed xserver 1.4.2, and my system has never worked better).
In your post, you suggested that releasing an older version "would inhibit our ability to work with upstream to gain real fixes to the problem" In fact, I would argue that releasing a legacy driver would only allow for a more sane release plan. Reading the notes by Keith Packard that you have cited above, it seems that Xorg is essentially treating -intel as a beta. Beta software is fine for early adopters who are willing to track down bugs and take the time to file intelligent bug reports, but it is counterproductive to distribute beta software at large. It does not produce more information, it simply infuriates individuals that have become unwilling beta-testers (see some of the above comments) and produces a large number of uninformed bug reports (see some of the duplicates). I think the best way to get to a working driver is to relieve some of the presure from the Xorg team by pushing out a legacy driver that gets normal users working systems, and then let the early adopters slowly work through the bugs in the -intel driver.
In your post, you also mentioned that releasing an outdated version "is the wrong thing to do." Well, it certainly doesn't feel right. And if everything was as it should, every version would improve upon the previous and releasing old versions would never be necessary. But alas, this does not seem to be the case. I think the right thing to do at this point is t...

@Bryce: Well, many people, myself included, wrote in the beta and RC wiki'ed release notes about it, but it seemed each new release reset the list of release notes, rather than engaging the people from the previous release and asking them if it was fixed or not. You'll see I've poped into the forums and offered my help there (using boot.local, for instance, to apply the MTRR fix to at least the first start of X).

To be honest, we're stretched pretty thin already just maintaining one
version of X.org. At over 180 separate packages, totally almost 2000
bugs[1], we've got a lot of work cut out for us.
I say "us" because while there is only one paid X.org maintenance
position, there are about a dozen volunteers who contribute a lot of
time maintaining various bits and pieces of the stack, without which
your X would be much worse.
Within a given Ubuntu release, all of the 180 X packages are tested to
work with the version of the xserver included in that release. Each
version of xserver provides a different ABI, that all X.org packages
have to be built against. Including a second version of xserver would
necessitate testing those packages against that version as well, and in
some cases providing two versions of those packages in order to account
for the ABI differences. For instance, even if we only supported a
single video driver with that second xserver, we'd need to package and
support two versions of each of the couple dozen input drivers, and
probably two sets of packages for xorg, xrandr, xinit, xauth, and on and
on. A LOT of work.
I don't think any OEMs shipping 8xx purchased support contracts with
Canonical that would help us justify putting resources into supporting
these older chips. But let's imagine that they did. In this case,
wouldn't it make more sense rather than pouring all that time and effort
into an xserver backport, to instead fund making the -intel driver work
better with the 8xx chips directly?
Now, given the large amount of bugs against 8xx, you might conclude
Ubuntu is not giving any attention to this chip. In fact that's not the
case[2], but getting proper support for it depends a lot on community
involvement. I can help by doing packaging, liaising with Intel,
giving coding advice, and even coordinating efforts, but I'm just one
guy and can't take on responsibility for supporting the chipset alone.
But I would love to help you and others like you in forming a
i810 development community[3] to get support that this chip deserves.

Btw. I guess most of this problems should be fixed in Karmic. I have tested -intel 2.7.0 with Kernel 2.6.30, UXA and KMS and it is very fast on my i915. All Compiz animations seems smoth and doesn't lag. Even textured video seems to be fast.
Glxgears shows still ~300 frames but as we all know it is no real benchmark. If textured video gets rid of the tearing before release the Linux driver will be better than the windows one because Aero doesn't run with i915 and finally Compiz will run without penalties (no blue borders, no not moveable 3D outputs and no flickering with 3d).

No need for any newer intel driver! Kernel 2.6.30-rc4 fixes the issue by itself! At least for my [8086:27a2] (rev 03) using EXA.
kernel 2.6.30-
* 1276 FPS for xserver-
* 885 FPS for xserver-
kernel 2.6.28-11-generic:
* 177 FPS for xserver-
* 420 FPS for xserver-
As you can see, with the default Jaunty kernel, reverting to the Intel video driver 2.4 improves the performance from 177 to 420 FPS (for 2D, you can tell it by playing a Flash in full screen), but the 2.6.30 kernel has two surprising effects:
* improves the performance of the 2.4 driver from 420 to 885 FPS, so roughly 2 times…
* …but the performance of the default 2.6 driver is boosted from 177 to 1276, so more than 7 times!

And I don't trust the IQ of hardcore gamers. Sorry to the offended guys.
§2: Yes, glxgears is *not* a benchmark. OK, instead if just counting how many times you can rotate some gears on the screen, it might actually count the number of frames, because of the call to glutSwapBuffers(); in gears.c, in the function draw(). From the doc:"The update typically takes place during the vertical retrace of the monitor, rather than immediately after glutSwapBuffers is called. ... Subsequent OpenGL commands can be issued immediately after calling glutSwapBuffers, but are not executed until the buffer exchange is completed."
However, please note that this is not normal to have the frame refresh rate *severely* changed by a KERNEL update, while using a same version of the video driver!
§3: Performance regressions can be seen in full-screen Flash too, and regressions are unacceptable. Watching a video or a Flash is not like gaming, yet it's necessary for a desktop/laptop usage.

UXA is noted here as a possible solution for EXA issues. What's wrong?
Test result for kernel-2.6.30rc2 + intel-2.7.0-1 (AccelMethod=UXA) on MSI Wind (Intel GM945):
Everything works stable, desktop doesn't freeze for almost 20 hours of work (earlier it was freezing every 1-3-5 hours).
There are no visual corruptions when moving or overlaying windows with compositing enabled (was fixed with very first UXA appearance indeed, and that is why only UXA is acceptable).
Compiz effects work subjectively smooth and fast, there are no such a lags as they were with kernel-2.6.28 with UXA enabled.
Fullscreen video plays normal, no lags.
So, it seems to me that problem was almost solved, except for this solution being "release candidate".

The problem is 3-fold:
(1) updating to intel-2.7.0-1 is useless unless a major kernel update is made too;
(2) updating to intel-2.7.0-1 is *not* necessary as long as simply updating the kernel to 2.6.30rc{2,3,4} fixes the issue for intel-2.6.3 (which is the official one in jaunty);

@Radu: Like it or not, most people prefer the ppracer frame rate as an indicator, you don't have to play the game, and can even uninstall it after doing the tests- but it's generally a better 'real world' indicator, and easier to get a FPS number from than Compiz or KDE4.
"GAMES ARE NOT A VALID BENCHMARK, except for gamers!"
I'm afraid in this case in particular, that's just wrong. There are many reports that show glxgears frame rate going down, but both subjective 'feel' and ppracer frame rate improving.
"this is not normal to have the frame refresh rate severely changed by a KERNEL update"
Actually, it's increasingly common, because a whole lot of what used to be in video drivers, or X itself, is now in the kernel, so called 'kernel mode setting' for one thing.
"full-screen Flash "
A good subjective test, but you can't get any numbers out of it, because Flash frame rate is limited by the plugin.

Now we just need to make pigs fly and put that into Jaunty updates.
I really find that ironic that I am already installing unsupported packages on my brand new Jaunty less than 2 weeks after its release. Usually I start messing with these things one month before the next release is due. Guess we just have to wait two more weeks before the user experience on Karmic becomes better than Jaunty's.

People say Mandriva 2009.1 has intel-2.7.0, and this whole issue solved. And I'm sure they didn't put R.C. into distribution ;-) And that means solution is somehow back-portable.
It is their luck that they have released two week after Jaunty, and got that solution working, I think...

As we were officially advised against UXA, I have not tried it, but I've just added it to xorg.conf, and, for kernel 2.6.28-11 with intel 2.6.3, glxgears suddenly raised (from 177 FPS with EXA) to 457 FPS, but I am puzzled by the following message: "Running synchronized to the vertical refresh. The framerate should be approximately 1/39 the monitor refresh rate."

@Radu: UXA (at least on vanilla Jaunty) is known to be unstable for
some configurations (including mine). Your mileage may vary, but in no

Radu Cristian Fotescu (beranger) wrote : | #371 |
@Gnurou : C'est tout à fait correct. Even if it doesn't freeze nor crash, UXA breaks hibernation: upon resuming, the screen is black and dead. I can switch to other VT, but not to restore the X session.
OTOH, all the reports concerning "Intel blabla [8086:27a2] (rev 03)" are almost useless: there are way too many different mobo architectures using the same chip ID, yet each of them behaves differently -- some work better, some work worse, some crash.
Sergei (Nolar) Vasilyev (nolar) wrote : | #372 |
Seems that hibernation is broken because of intel driver too.
I've just tested it on my MSI Wind U100, and system hibernates and resumes normally only after deleting "splash" kernel option from /boot/grub/menu.lst for 2.6.30-rc2 kernel (option "quiet" has no matter). With "splash" option system freezes in text mode; AltF1 allows to see few strange messages; but nothing happens then.
This issue does not relate to X performance and corruptions directly, of course, but splash screens use video mode switching somehow. And, as I know, they try to implement seamless graphical booting with use of KMS in new kernels. Maybe that's it.

One of the specific issues that has been identified on Intel graphics, is that we no longer have an MTRR for the AGP aperture. We look to have isolated the issue there, and have produced test kernels. For those of you with Intel graphics on Jaunty perhaps you could test the kernels listed on bug #314928.

Upgrading from xorg-edgers (in addition to linux-2.6.30) solves the freezes. Upgrading from ubuntu-x-swat doesn't help, but I think it is some library (libdrm or mesa) that solves the freezes, not the intel driver itself, because upgrading from xorg-edgers (with intel-2.7.99) and then rolling back to intel-2.7.0 from ubuntu-x-swat also solves the freezes.

It's was a clean Kubuntu 9.04 install with only the kernel added in.
I'm not sure if I was using UXA or EXA. I didn't change the xorg.conf.

Well, I installed the 2.6.30rc7 kernel, libdrm/libdrm2 and the intel driver from xorg-edgers .
The rendering errors with Compiz are corrected, I don't even see crashes now, but still no performances improvements ...

Richard Guo (rfguo) wrote : | #389 |
@bouazza: Yes, I still have crashes, but they're much more infrequent now (once every 2 days). I did a dist-upgrade after adding the PPA, so there may have been other packages (most likely mesa) fetched as well. How are you measuring performance improvement?
NB (n4xxx) wrote : | #390 |
@bouazza: I means that Tux Racer now runs at 25-35 FPS instead of 1-2 in Jaunty. Just by adding UXA it was only 10-25 FPS. I followed ALL the "Bleeding-Edge Configuration" steps in the guide, else the performances was almost unchanged; but the configuration and the result may depend on your graphic card.
In default Jaunty some games under Wine are unplayable: even enabling UXA didn't help. Of course I don't mean to play current 3D Windows games on a little i945 and I don't expect to get the same performances under Wine. Anyway that guide made them playable again. I don't remember the exact Wine performances on Hardy, but Jaunty with this changes seem faster. Tux Racer is faster for sure (it was around 15 FPS). Compiz effects are no longer choppy and the 2D is also OK (it don't looks slower than Windows), so I no longer miss Hardy.
bouazza (sbouazza) wrote : | #391 |
Well, when I measure performance improvement, I usually use PPRacer, but even if the FPS goes from ~5 to ~20~30 ( Intel X3100 card ), I still think that there's no improvement ...
We have to compare to the Intel graphics performances under Windows XP ( my brother's PC with its Intel 8XX card runs games much faster on Windows ... ), and not to those under previous versions of Ubuntu ( people here compare to Hardy I think, which itself has poor graphics performances than Windows ) .
NB (n4xxx) wrote : | #392 |
I would call a 4-6X improvement an HUGE improvement. However it was Jaunty (and Intrepid) that showed a big drop in performances, so with that guide I can use Compiz and some Wine games again as I did on Hardy. And that is why people compare Jaunty to Hardy. The modified Jaunty performs better than Hardy on my hardware: Extreme Tux Racer is 2 times faster as I said before, so there is an improvement. But you are right: Hardy was slow, compared to Windows and there is still room for more improvements. I'm not saying I'm totally satisfied.
I'm not sure if I can directly compare Exrteme Tux Racer to the Windows port, anyway Extreme Tux Racer for Windows hits 50-60 FPS, a lot more than that "Bleeding-Edge Configuration" for Jaunty.
bouazza (sbouazza) wrote : | #393 |
The reason I'm not satisfied with this "improvement" is that we are just back to the Hardy performances, so nearly 0% loss and gain on graphics performances ...
But even on Hardy, Windows games that were smoothly playable under Windows Vista are totally unplayable now, even with these "improvements" ...
We can talk about improvements only if we can really compete with Windows, also, if this goal will be achieved, then Ubuntu will really rule the notebook market ( since 90% of notebooks are based on Intel graphics ) .
Mike Kaplinskiy (mike-kaplinskiy) wrote : | #394 |
@bouazza: we're not quite there yet. In fact, we haven't even begun talking about catching up to windows. The main reason is that the graphics drivers for intel are currently (relatively) unstable. If you read the bug description, intel is doing a major rework of their linux drivers.
In particular the two outcomes of this are two new driver components: GEM and Gallium3D. GEM has been introduced into the release, and most of the performance decreases from hardy were due to GEM being unstable (ie failing on certain hardware). The next step would be to move the Mesa Gallium3D driver into ubuntu, and i am 95% sure it's not happening until karmic. Then we can talk about catching up to windows, since as of now intel drivers crash on anything more than glxgears (GLSL makes them cry).
For an example of current developments in the intel linux graphics world - EXA support was recently removed, so we're moving closer to a single stable intel backend driver (on UXA only). But this is not making it into jaunty since it requires the new kernel. Bottom line - you probably shouldn't expect "improved" (as you define it) intel performance on jaunty without manual tweaking. Or you could just update to the karmic alpha :).

Dear Benjamin MOTU,
Whatever is needed to be "specific" about this bug is written in the Ubuntu 9.04 Release Notes, right here:
http://
"Users of Intel video chipsets have reported performance regressions in Ubuntu 8.10 compared with previous releases (252094). Many of the issues have been resolved in Ubuntu 9.04, but some remain."
By declaring this bug as "Invalid", you're suggesting that the Ubuntu Release Notes are LYING. Next you should probably deny that the Holocaust ever existed.
The Internet is full of THOUSANDS of proofs that recent versions of xserver-
Mark Shuttleworth should simply send you to the garbage bin. You're undermining Ubuntu's reputation (if any of it left after shipping a release with Intel performance dropped to 10%).
Bryce Harrington (bryce) wrote : | #402 |
Radu, your comments are inappropriate, please remain civil. Remember many of the people assisting with people's bugs are volunteers, and expressing your frustration here (while valid) does not help move things towards a solution.
In this case Benjamin is correct, and is simply repeating information already provided earlier in the bug report.
I am closing the Karmic task because the causes of the performance issues on Jaunty are no longer valid on Karmic. There are still some performance issues being tracked, but they're particular to Karmic and due to unrelated reasons; we expect all performance issues should be resolved by Karmic Alpha-3 or Alpha-4.
The causes for performance issues in Jaunty have already been well characterized in other bug reports, and kernel patches are being tracked for potential SRU into Jaunty, if they do not expose other regressions.

It was affected on the day of the release, packages from karmic are
*official* and have been backported via PPA and do fix the problem.
Right now it's the waiting time to decided what will qualify for SRU.
It is Ubuntu policy not to include new versions of software after the
release.
Noone forced you to upgrade to Jaunty. Hardy is LTS and still
supported. If you want stable and long-term machine use LTS releases.
If you upgrade on day of the Release well you should expect that not
everything will work as *you* wish it to work. Look how KDE 4.0 worked
out and you have installed Jaunty 9.04.0 - point 0 version!

He never mentions the fix. I haven't had time to look through the
intel forums to find the thread with the discussion.

Use of the rc kernels is a bad idea. You risk loosing functionality.
Best practice would be to use 2.6.29 and back-port all the GEM revisions.
( compare the two kernels and copy source files from one to the other )
I used to do this a lot. To me 2.6.24 was the best so I'd port back
all the junk I liked in the newer kernels. It's time consuming but
worth it if you want to keep everything going. Think Red Hat here.
Below is what I have:
1.mesa-git/glew-git
2.linux-2.6.31rc5
3.xf86-
Not much of an improvement.

Figured I'd make an update.
Mesa git fixed some issues for me.
unreal tournament isn't hoping around anymore.
Actually is pretty smooth now.
Blender's latest available build still renders outside the container
window but some of the glitches were fixed. You still can't see the
selection window.

Same problem here, with an intel x3100 card (on a Samsung Q45).
Up to 8.04.1 (Kubuntu) I was able to use KDE4 'desktop effects' easily.
Also, sInce upgrading to 8.10 Alpha 3 (from 8.04.1), desktop effects are not working, enabling them results in a mainly black, garbled screen.
