[i915gm] X freezes with I830WaitLpRing error when using firefox

[g.marella]

Binary package hint: xserver-xorg-video-intel

Apparently with no reason (I was using firefox) the screen freezes filled with a mostly black pixelized pattern. After some "flashing" trying to automatically restart the server, it ends up to the message telling "ubuntu is running in low graphics".

Switching to a shell prompt to restart gdm or with startx isn't working. Following the option to start in low graphics right after the message telling "ubuntu is running in low graphics" takes me to the gdm login screen.

Please sorry if I've made some mistakes and let me know how to help more.

Thank you for reporting this bug and helping making ubuntu better. There has been a number of fixes in Jaunty, the new development version and we would like to identify bugs that still remain there. Could you try to boot from a recent daily-live CD-image that you can find in http://cdimage.ubuntu.com/daily-live/ and see if you can reproduce the bug there?

[Geir Ove Myhr (gomyhr)]

One more thing: This has very similar symptoms to bug 285298 (which already has 4 duplicate bug reports). Could you have a look and see if it you think it could be the same bug?

[g.marella (giuppi)]

I'm not able to find a way to reproduce to error. Since I don't have hardware acceleration I cannot even start amoeba like stated in the bug 285298

[~] amoeba -windowed -nosound
Couldn't open GTK+ interface (disabling because of command line options), reverting to command line.
Unhandled exception: No direct rendering (hardware acceleration) available! (Check libGL.so.* symlinks)

Yesterday evening it happened again. I was running -among the others- firefox, amsn, liferea, truecrypt, dropbox and awn. compiz is enabled but only few essential plugins are enabled. Uptime was 2d 2h more or less. I don't power off but suspend to ram instead.

By now I've upgraded xserver-xorg-video-intel to version 2.5.1 from https://edge.launchpad.net/~intel-gfx-testing/+archive even if I haven't understood if there really is any difference with the previous one.

I'll take the time to download and try the daily-live cd and maybe upgrade using this repository https://launchpad.net/~xorg-edgers/+archive/ppa

[g.marella (giuppi)]

I'm now using the updated driver from xorg-edgers repository since a couple of weeks and the problem in the bug report title has gone.

Thanks to everyone :)

Thanks for letting us know the issue is fixed in a newer driver. Can you tell which version you installed? You can get this info easily via:

apt-cache policy xserver-xorg-video-intel

[g.marella (giuppi)]

the error in I830WaitLpRing seems to have gone. Some issues still persist, with screen freeze and gdm restarting mostly after entering the password at the screensaver lock dialog or restarting the machine from suspend to ram. I'll submit a new bug report if able to understand where the error is.
