Well... it just happened again while browsing Youtube videos (unfortunately I was not running GTKrecordmydesktop) and when looking at the /sys/kernel/debug/dri/0/i915_error_state file via SSH, both EIR, PGTBL_ER, and all of the IPEHR's where displaying 0x0000000.
However, before this particular lockup I a was able to record a previous lockup which manifested itself a little differently - instead of locking up the entire interface, leaving me with only being able to move the mouse, it looked more as if everything besides the root X server crashed, leaving only the bare windows of the applications visible, without any decorations. I could still interact with the applications (at least those who were on top, switching between applications no longer worked) and could also still use CTRL-Alt-F1. After rebooting the machine from there, Apport prompted me with the same lockup detection as before. The last thing I did before this happened was dragging an application window to the right. Anything else I can do to get this sorted out? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/975083 Title: [sandybridge-gt1] GPU lockup To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/975083/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
