A valid gpu dump was not collected in this case, and since there was no noticeable failure I'm going to close the bug report out as a false positive.
If I had to guess, I would suspect that virtualbox being installed may have caused a conflict with the video driver, which freaked i915 and caused the false gpu error to be triggered. but who knows. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/763747 Title: [i965gm] GPU lockup -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
