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 Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/541492 Title: MASTER: [i845] GPU lockup To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/541492/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
