[i965] intel gm965 compiz dual head issues

[relik]

I have an IBM Thinkpad T61 with the Intel GM965 (X3100). I have a docking station that uses a DVI and a VGA output for dual monitors. I do not use my laptop monitor. I have gotten dual heads to work as clone as well as expand. However, when I put my monitors in extend mode, compiz turns the desktop completely white and everything on my desktop disappears. The 3D Cube still works fine as well as all the other features except my desktop is completely white. Can't change the background etc. I believe I have the issue why this is happening.

If I add the Virtual line of 2560x1024, compiz spits out an error:

Comparing resolution (2560x1024) to maximum 3D texture size (2048): Failed

If I turn my resolution down down to 1024x768, it works fine.

I think Compiz is spitting out the wrong 3D texture size and hoses on it.

If I change my /usr/bin/compiz config, and change the Failed to equal 1 (which is success), compiz works fine except for the odd looking white desktop background. Again, 3D cube works fine, wobbly windows, everything. Except for the desktop. Very strange.

[David Portwood (dzportwood)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, this compiz package is not from the official Ubuntu repositories, and as such is not supported here. Please report this bug upstream at https://bugs.freedesktop.org/enter_bug.cgi?product=xorg . Thanks!

[David Portwood (dzportwood)]

I closed the wrong set of bugs, sorry.

[Travis Watkins (amaranth)]

Your video hardware is not capable of running compiz at this screen resolution.

[relik (dkennedy)]

Travis, how is that possible when it works 100 percent fine if I install Compiz from hand on Feisty? I have it working right now at 2560.

[mexlinux (mcanedo)]

I have this problem on Hardy (only official packages),
The dual head with 1024x768 + 1280x800 works only on metacity.
Compiz only works up to 1024x768 + 1024x768
This thread is confusing.... is this a bug or a hardware limit?

[Travis Watkins (amaranth)]

It is a hardware limit that compiz from upstream does not enforce, we do it via compiz-manager. If you install compiz from upstream (like relik did on feisty) compiz will start but with have rendering problems on the part of the screen that goes over this limit.

[mexlinux (mcanedo)]

wired....
I'm not completely sure on how to reproduce it, but sometimes compiz works on the dual head, and in fact have rendering problems, but only on the background, The windows, even in that area are properly rendered.
See attachment, also in the attachment there is dump in the console of th xrandr output

[mexlinux (mcanedo)]

Second scrennshot it to proof that compiz is runing, and also how rendering is viewed.

[Vitali Kulikou (sabotatore)]

I have the same problem!

[ajonat (ajonat)]

Hi!
This page http://www.intellinuxgraphics.org/dualhead.html shows the following in a xorg.conf example for configuring dual-head:

# This optional entry specifies the virtual screen resolution to be used.
# If this entry is not present, the virtual screen resolution will be set to
# accommodate all the valid video modes given in the Modes entry.
# There is a known issue that DRI doesn't work on pre-965 if maximum is larger than 2048x2048.
Virtual 2048 2048

So, I don't understand... if it is really a hardware limit, how come the official intel graphics page says it doesn't apply to 965GM and later cards?

Thanks in advance!

[Travis Watkins (amaranth)]

In that case I'd say it's a driver bug. It either really doesn't support larger than 2048x2048 or does but is reporting that's all it supports. That's what compiz is checking on the bit that fails, what the graphics card claims the limit is versus your current resolution.

[Travis Watkins (amaranth)]

Actually based on the white background you mention the limit _is_ really there. If it shouldn't be then the driver is supporting less than the hardware.

[unggnu (unggnu)]

The driver problem might be a dupe of Bug 146859.

[ajonat (ajonat)]

Travis, you were right, the drivers were the problem.
Here's what I did to make compiz work with larger resolutions (beyond 2048):
First, I did apt-get source xserver-xorg-video-intel and applied the following patch:
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-intel.git;a=blobdiff;h=ada3919adf33179ab72aecfdc2e9e48c439f8888;hp=7f798e6c8dfb0a5775cae5d4e6595d8d09b2a251;hb=4f5500abe209b92b39ae1f2d7a1118362ac95034;f=src/i965_render.c
What this does is to enable support for larger resolutions (up to 8192x8192) in the i965 driver, as you can see in the diff:
- if ((w > 0x7ff) || (h > 0x7ff))
+ if ((w > 8192) || (h > 8192))

Then, I applied the following patch in mesa7.0-rc3 (latest in ubuntu hardy):
diff --git a/src/mesa/drivers/dri/i965/brw_context.c b/src/mesa/drivers/dri/i965/brw_c!
index 1601f6d..c06f5da 100644

@@ -138,10 +138,10 @@ GLboolean brwCreateContext( const __GLcontextModes *mesaVis,
    /* Advertise the full hardware capabilities. The new memory

- ctx->Const.MaxTextureLevels = 12;
+ ctx->Const.MaxTextureLevels = 13;
    ctx->Const.Max3DTextureLevels = 9;
    ctx->Const.MaxCubeTextureLevels = 12;
- ctx->Const.MaxTextureRectSize = (1<<11);
+ ctx->Const.MaxTextureRectSize = (1<<12);
    ctx->Const.MaxTextureUnits = BRW_MAX_TEX_UNIT;

 /* ctx->Const.MaxNativeVertexProgramTemps = 32; */

Then, I dpkg-buildpackage xserver-xorg-video-intel and mesa7.0rc3 with both patches applied and installed them, and voila! Problem solved.

ajonat@daphne:~$ glxinfo -l | grep GL_MAX_TEXTURE_SIZE
    GL_MAX_TEXTURE_SIZE = 4096

This limit is because mesa can't handle resoutions larger than 4096 but that isn't problem for me as I wanted 2960x1050.
You also have to put the according virtual resolution in xorg.conf for this to work.

Thank you everyone!
Alex.

P.S. any chance to see this patches applied to hardy's latest packages?

[ajonat (ajonat)]

Now I'm having this bug: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/149377. I'm going to do a little research and come back posting my findinds.

[Bryce Harrington (bryce)]

Hi dkennedy,

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with the latest development release of Ubuntu? (ISOs are available from cdimage.ubuntu.com)

If it remains an issue, could you also attach a new /var/log/Xorg.0.log?
Thanks in advance.

The output of lspci -vvnn would also be worth having.

[Bryce Harrington (bryce)]

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

[Ramon Casha (rcasha)]

It's actually still there. Any combined resolution beyond 2048 pixels in width disables the eyecandy

[Ramon Casha (rcasha)]

still present on intrepid

[relik (dkennedy)]

Still an issue on intrepid, not fixed. I've since switched to another distro due to the responses I received "its a hardware limitation" and "this is not supported". I've gotten my "hardware limitation" to work successfully on SuSE without a problem.

[Matthew Woerly (nattgew)]

I have the same issue, compiz dies if it's larger than 2048. My workaround is to put the second screen on top rather than on the side.

[mexlinux (mcanedo)]

@Nattgew
Your work arraound works here too, Thanks!
Is a bit wired to have that position, but at least works....

[snuggl (snuggl)]

workaround (to start compiz, not to get rid of the texture limit), start with this if you dont want to edit the wrapper:
SKIP_CHECK=yes compiz --replace&

Problem still exists in Intrepid

[Chris Jean-Marie (chris-jeanmarie)]

Only the mesa patch is now required in Intrepid. The i965 driver can now handle the larger screens.

[Tormod Volden (tormodvolden)]

The link to the mesa patch above is broken, it is http://lists.freedesktop.org/archives/xorg/2008-April/034707.html

[mexlinux (mcanedo)]

I have just installed KDE4.2 Beta 2 and works PERFECT!

So I might "guess" that is not a problem in the driver, but in compiz..... might that be?

[mexlinux (mcanedo)]

I mean when running kde 4.2 I'm using kwin, instead of compiz.

[Bryce Harrington (bryce)]

[This is an automatic notice.]

We'd like to forward your bug upstream, however upstream requires
that you first test it against their newer driver code.

To save you the effort of building the driver from source, we've built
packages for the driver and its new dependencies.

So you have a couple options:

 1. Download and test .debs for intrepid, from:
     https://edge.launchpad.net/~intel-gfx-testing/+archive

 -or-

 2. Download and test the Jaunty alpha-2 (or newer) Live CD,
     (which includes a beta of the new xserver 1.6 as well).
     See http://cdimage.ubuntu.com/releases/9.04/ for ISOs

Thanks ahead of time! You can simply reply to this email to report your
findings.

P.S., if you wish to forward your bug upstream yourself, please follow
these directions to do so:
  http://intellinuxgraphics.org/how_to_report_bug.html

[Ramon Casha (rcasha)]

Ok I installed the Intrepid debs. Didn't seem to make any difference to tell you the truth. I'm currently running on dual screens of 1600x1200 and 1600x1024 (xorg.conf has Virtual 3200 1200).

Attempting to enable the visual effects gives "Desktop effects could not be enabled".

Running compiz gives:

Checking for Xgl: not present.
Detected PCI ID for VGA:
Checking for texture_from_pixmap: not present.
Trying again with indirect rendering:
Checking for texture_from_pixmap: present.
Checking for non power of two support: present.
Checking for Composite extension: present.
Comparing resolution (3200x1200) to maximum 3D texture size (2048): Failed.
aborting and using fallback: /usr/bin/metacity

Are there any tests you want me to try or anything?

[Bryce Harrington (bryce)]

Thanks for testing; this should go upstream. Setting to Triaged for now.

[miloos (milooos)]

I spent few hours by solving problem with dual monitor on intel on board 810.
After set 1st monitor left the 2nd and when GUI wrote virtual display size to xorg.conf X doesnt start correctly. (it was looked like 1st row of screen is on whole screen)
I was looking for solution: how to disable direct rendering, but these .debs solved my problem and I have direct rendering enabled.
thank you

[Khashayar Naderehvandi (khashayar)]

This patch from upstream [1], commited 4 hours ago, is very similar to the one in comment 16. It's supposed to bump the texture limit on i965 to 4kx4k. I'm about to test it in a minute on Jaunty, where it's the only change required to solve this issue. If it works, I suggest it should be cherry picked and applied on Jaunty's mesa.

[1] http://cgit.freedesktop.org/mesa/mesa/commit/?id=954dfba12986f578f2d8461818f9e9ac1f8f2b41

[Khashayar Naderehvandi (khashayar)]

I can now confirm that the patch from upstream solved the issue on Jaunty, and that it's the only change required.
I changed the affected project of this bug to mesa. (Well actually, I was trying to add mesa, but for some reason xserver-xorg-video-intel was replaced with mesa).

[Ramon Casha (rcasha)]

Any chance that this can also be applied to Intrepid?

Could anyone test it, please?

Here is the debdiff:

[Reopening; even though we think this patch may solve this freeze, we need positive testing proof still.]

[Bryce Harrington (bryce)]

er, let me try that again...

We suspect the fix for this bug has caused a more serious X freeze issue (bug 359392), so are reverting this patch for now. We might bring it back later if we can definitively prove what causes that freeze.

[bigbrovar (bigbrovar)]

i doubt the fix is the cause of the serious X freeze, i upgraded from beta to jaunty RC (clean install) and the first thing that greeted me was a freeze,

[salvabalza (salvabalza)]

Hi all,

with the patch of April, 3th it solved for me, I could see compiz and its effects on both screens.

With today jaunty update, I have the problem again, I can see compiz on only half on second screen (maximum 3D texture size (2048) problem).

[Ludovico Cavedon (cavedon)]

I uploaded in my ppa version 7.4-0ubuntu3+ppa1 which reenables the fix.

https://edge.launchpad.net/~cavedon/+archive/ppa

[Matthias Blaicher (blaicher)]

Your PPA is out of data again, it would be great if you could patch the most recent version as well (mesa-7.4-0ubuntu3.1). Also it seems that there is now a fix to the intel problems, and I bet this patch has nothing to do with it, as it was a bug in the intel driver and not mesa. (See Bug 359392)

Updated! Thanks for letting me know!

[Ludovico Cavedon (cavedon)]

This fix was removed from the package just before release because it was thought to be the cause of bug 359392.
Now that it has been made clear that it is unreleated, would it be possible to make SRU for jaunty?

I am attaching a debdiff.

[achansonjr (a-c-hansonjr)]

Ludovico Cavedon's ppa repository has me up and working on a fully patched 9.04 install. Thanks Ludovico.

Should this be working on jaunty? My compiz still checks for the resolution
and fails with the message

..before falling back to metacity. Did I leave something out?

The mesa package in my ppa should fix the problem:

[Ramon Casha (rcasha)]

Yay it worked.
Not sure what I did though - first time I tried it, it didn't work. Maybe it needed a reboot?

[Ochir (oabushinov)]

I tried this patch for my intel GM 4500 MHD card and it works well.
Thanks!

[Ochir (oabushinov)]

sorry, I forgot to add. I applied patch by Ludovico Cavedon for Jaunty.

[Timo Aaltonen (tjaalton)]

Fixed in karmic, which has mesa 7.5rc4. Too risky to put in jaunty.

[David M. Lee (leedm777)]

That's disappointing. Cavedon's PPA is working great for me.

[Valentin Neacsu (valentin.neacsu)]

Works with Ludovico Cavedon's PPA. Thanks!

[Frantique (undernetangel)]

Cavedon's PPA helped me too. Thanks!

[Stuart Colville (muffinresearch)]

I've tried Cavedon's PPA a couple of times but it always produced tearing even after reboot - so I downgraded back the packages that were replaced.

However just to be sure I'm not getting something wrong - could someone provide details of steps to install the patched version of mesa?

[Johan van Zoomeren (amain)]

Cavedon's PPA helped me too. Great Thanks!

[dRewsus (drewsus)]

Cavedon's PPA needs to be updated for Lucid and Mesa 7.8.1

[Adam Koczur (sbv)]

Really disappointing - still not fixed in Maverick.

[Gerardo Lisboa (gvlx)]

Latest packages for Natty still do not apply the patch already present in Mesa's HEAD branch.
