As a further update to my previous comment, while the xorg-edgers ppa has resolved my problems to the point my system is useable when running compiz, time has revealed slightly more severe problems than previously reported. Largely it's as I said - as long as I ignore the error report, everything works pretty much fine. But I have gotten a few system-wide crashes since I last commented - most commonly right after I log in. If everything goes fine in the few minutes after login, I generally have a stable system after that, as long as I cancel the option to report any errors.
I hope that's helpful information to anyone tracking the issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/980017 Title: [i965gm] GPU lockup render.IPEHR: 0x02000004 To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/980017/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
