jaunty unbootable on intel G45 since .28-5 kernel update

[Martin Olsson]

I installed the .28-5 kernel update for jaunty that hit the updates today. Now my machine fails to boot. I never get to GDM, all I see is a very garbled screen. If I move the mouse the garbage on screen moves as well. I suspect it's actually a corrupted version of the "Ubuntu is running in low graphics mode" that I'm seeing, but I'm not sure. I still got the 2.5.1 version of the intel DDX driver but I did get the new libdrm etc.

I've been previously running this machine with the special intel drm patches that where merged into .28-5 and I never saw any problems with those (in fact these patches fixed an important drmWaitForVBlank bug for me). I'm talking in particular about the "don't enable vblank for disabled pipes" patch etc.

I'm attaching a photo of the screen corruption so you get the idea.

I'm also experiencing this problem after applying today's updates. TTYs work fine, but GDM displays a black-and-white garbled screen. If I go to a tty and run a ps -e, I can see some failsafeXinit processes, so I guess it's using the vesa driver, which seems to be broken.

My card, as reported by vista, is a "Mobile Intel 4 Series Express Chipset Family". If you need any other information, just ask.

By the way, martin, I couldn't open your photo. What format is it in?

[Timo Aaltonen (tjaalton)]

it's a proprietary Nikon raw file format. Please use jpegs :)

and try without usplash

[Timo Aaltonen (tjaalton)]

and also make sure that you have -5.15 installed.

[Martin Olsson (mnemo)]

Sorry about the proprietary file format crap, I did convert it before opening the bug but then I accidentlly attached the unconverted file by mistake.

I see the *same* garbage on screen (it's got the same shape, color, etc). But TTYs and Usplash work fine here. The garbage appears with gdm. If you need any information about my system, just tell me.

[Timo Aaltonen (tjaalton)]

this should be fixed as soon as the new -intel driver is built on amd64...

[Emilio (turl)]

Nice, I was about to post my debug info, but I think it isn't needed anymore.

[Jeffrey Baker (jwbaker)]

Is there a place where I can get the latest package? It hasn't hit the archives yet.

[Jeffrey Baker (jwbaker)]

Eh, I found the 2.6.1 sources on launchpad but they fail to build from source because mesa 7.3 isn't built on amd64 yet. I would recommend not setting this to "fix committed" until the package actually builds.

I have a similar problem on a GM965. Broke just after latest kernel update to .28-5, boot process is fine until xorg tries to start... the screen flickers a few times, then I am left with a greenish bar in upper-left corner... corrupted graphics. This is AMD64 Jaunty. Should I file a new report specific to the gm965? I assume it is the same issue. I'm new to helping out with bug reports and all, so let me know what information from my system would be useful.

[kaervos (eudoxus)]

Well, after poking around with aptitude, I see that I have xserver-xorg-video-intel=2:2.5.1-1ubuntu7 installed, but running aptitude changelog xserver-xorg-video-intel, I see that 2:2.6.1-1ubuntu1 is the latest version... this is only available for x86 right now, I am to assume? Aptitude can't see this version in the repos. I guess I'll just hold my horses for the package to be available. An ETA would rock, if possible. Also, with this update and mesa 7.3, will we have OpenGL 2.0 support?? *drool*

Cheers Timo, keep up the good work.

[Martin Olsson (mnemo)]

I got the -5.15 kernel now and I just got intel DDX driver 2:2.6.1-1ubuntu1 through apt. This fixed all my booting problems.

If someone else is still having problems after installing 2.6.1 of the intel xorg driver please post here asap. Otherwise I suggest this bug be closed with fix released. Thanks Timo.

My grabled screen was fixed with 2.6.1 (AMD64), however I still can't start gnome even on failsafe, just xterm.
It crashes shortly after loading background and goes back to GDM.
With Vesa it loads normally.

Dunno if these are relevant:
** Message: Got disconnected from the session message bus; retrying to reconnect every 10 seconds
x-session-manager[3989]: WARNING: Detected that screensaver has left the bus
x-session-manager: Fatal IO error 11 (Resource temporarily unavailable) on X server :0.0.
gnome-settings-daemon: Fatal IO error 104 (Connection reset by peer) on X server :0.0.

[Martin Olsson (mnemo)]

Marking as fix released.

Saku I believe you have a separate bug. Can you please repro your xorg crash and when you get back to GDM then ssh into the box and save /var/log/Xorg.0.log, /var/log/Xorg.0.log.old and attach them to the new bug report along with dmesg > dmesg.txt and also "lspci -nn > lspci.txt".

[kaervos (eudoxus)]

Today's updates of mesa w/ xserver-xorg-video-intel 2.6.1 fixed my problems as well.

Now from glxinfo:

OpenGL renderer string: Mesa DRI Intel(R) 965GM GEM 20090114
OpenGL version string: 2.1 Mesa 7.3-rc3

Time to write some OpenGL 2.0 programs. ^_^

Cheers.

Wow, even though Compiz-Fusion acts wacky and runs poorly now, the performance of my OpenGL programs is through the roof.

I tried to reconfigure Compiz-Fusion to no avail... any ideas what may be at the root of it's strange behavior and poor performance after this update?

[kaervos (eudoxus)]

Compiz-Fusion's poor performance has been fixed by the latest DRI / Mesa update. Everything is glorious once more.
