Comment 85 for bug 28326

This bug is still present in Feisty as per today (xserver-xorg-video-i810 2:1.7.4-0ubuntu1, linux-image-2.6.20-13-lowlatency 2.6.20-13.21).

I can go through several suspend/resume cycles with no problem sometimes, but then as soon as an application tries to paint video to the screen there is a crash. The crash does not occur until the video is actually painted to the screen; the video window can be sitting behind other windows on the desktop without causing a crash.

Description of a crash with feisty: when I bring the video window forward it is all blue rather than containing any video. Then the screen goes blank and starts to display a moving band of video artifacts towards the bottom of the screen. I can still move the cursor mouse, but the machine does not respond to e.g. ctrl-alt-f1, ctrl-alt-backspace, ctrl-alt-delete. There is disk activity. The machine does shut itself down gracefully when I press the power button.

I get the following in syslog, the last two messages repeating, indicating, I presume, that kdm repeatedly tries to restart the X server without success:

Apr 1 09:04:21 machine kdm[5191]: X server for display :0 terminated unexpectedly
Apr 1 09:04:22 machine gconfd (user-6570): Exiting
