I confirm that graphics run a lot more stable now, however, the issue is not gone:
I had been working around the lockups by setting Option "DRI" "false" Option "Shadow" "true" in my xorg.conf Recently, I wondered if the problem still exists, and I removed these lines. The machines ran quite stable in day-to-day life, but I could still reproducibly crash the GPU running the demo of "celestia (Gnome)" (part of the edubuntu package). The weird thing is that after approx. one week, crashes started to increase a lot, and I had to reenable the DRI/Shadow workaround. Note that these machines are LTSP clients, all graphics goes across the network. I have the impression that GPU lockups occur when network traffic is high, i.e., X needs to wait for graphics data more often. All in all, things have improved a lot, but the problem has not "magically disappeared". I don't believe it's fixed. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/541492 Title: MASTER: [i845] GPU lockup Status in X.org xf86-video-intel: Fix Released Status in “xserver-xorg-video-intel” package in Ubuntu: Triaged Status in “xserver-xorg-video-intel” source package in Lucid: Triaged Status in Baltix GNU/Linux: New Bug description: Binary package hint: xserver-xorg-video-intel This is a MASTER bug report, i.e. not a real bug report, but a tool to help manage other bug reports. Most bug reports on i845 are probably due to the CPU/GPU incoherency problem that is now consolidated upstream at http://bugs.freedesktop.org/show_bug.cgi?id=26345 . For now, we mark all automatically reported GPU lockups as duplicates of this unless there is a reason not to. To use the available fix, run the following commands: apt-add-repository ppa:glasen/855gm-fix apt-add-repository ppa:brian-rogers/graphics-fixes apt-add-repository ppa:glasen/intel-driver aptitude update aptitude install linux 855gm-fix-dkms aptitude dist-upgrade There is a similar master bug report for i855 at bug 541511.
