If you want to troubleshoot why the udev rule doesn't trigger, you could listen for uevents with `udevadm monitor --property`. It would be interesting if you could upload the output of that here (when the error triggers) since I haven't actually seen those events before. I think you will only see one of the three events described in /lib/udev/rules.d/40 -xserver-xorg-video-intel.rules on i945, since the reset should only happen on i965 and newer.
There is an UdevLog.txt automatically uploaded with this bug report, which seems to be taken from /var/log/udev, but that seems to only record the events generated during boot (all the events are merely seconds apart and no new events are logged there when I unplug/plug a monitor). I attach the output of the above command when I unplug the external monitor and plug it back in 30 seconds later. The output for the GPU error event(s) should be similar. ** Attachment added: "udev-example.txt" http://launchpadlibrarian.net/49547959/udev-example.txt -- [i945gm] X crashes randomly (lucid) https://bugs.launchpad.net/bugs/587708 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
