Awesome - thank you VERY much, I'm happy to report that adding the xorg- edgers repository has largely solved my issues.
For information, I am still getting the error message a few minutes after startup most of the time (a few times it has not happened). And if I try to report it it seems to freak out and spawn infinite errors. But if I cancel reporting it and ignore it, then there's no further issue, I receive no further error notifications, and Unity + Compiz seem to be working fine together. When changing some settings in the Compiz Manager and on a few other occasions, it seems as though Compiz has rebooted itself (I briefly get a blank desktop with nothing but my wallpaper before everything reappears), but this has only happened to me on once outside of actively fiddling with the Compiz settings and every time it's recovered in 2 - 3 seconds rather than crashing and dying, or providing a corrupted display as it was previously. It's very useable now as long as I don't try to report that initial error. *gigantic thumbs up* Thanks again for being so helpful, Ben! -- 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
