Okay, some updates. I wrote a cron script for this system that would automatically record a batchbuffer dump and reboot if and when a GPU crash was detected. This worked well... a little too well. The crash was now occurring before GDM could even auto-login the user, and once I got thirteen dumps in a little over an hour (all attached here in a single tarball), I figured I may as well go with xorg-edgers---because it couldn't possibly be any worse than this.
So the system has been apt-get-upgraded with the xorg-edgers PPA, and 'Option "DebugFlushCaches" "1"' in /etc/X11/xorg.conf, and everything is running smoothly so far. I'll report back here if and when it starts acting up. ** Attachment added: "Thirteen batchbuffer dumps (from stock Karmic system)" http://launchpadlibrarian.net/36248815/dri_debug-multiple.tar.gz -- [i845G] Display freezes (except for mouse pointer) without warning https://bugs.launchpad.net/bugs/484020 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
