These gpu lockup bugs typically involve your computer freezing (except sometimes the mouse cursor moves), with a blank screen or the screen no longer painting or responding to clicks. Only way to recover is to power cycle your computer.
Do you ever notice problems such as that? From the log message it appears you did experience that at one time. (Reason I ask is we sometimes get false positives with the capture tool.) ** Summary changed: - i915gm GPU lockup ESR: 0x00000001 IPEHR: 0x7d8e0001 + [i915gm] GPU lockup ESR: 0x00000001 IPEHR: 0x7d8e0001 ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/746826 Title: [i915gm] GPU lockup ESR: 0x00000001 IPEHR: 0x7d8e0001 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
