Please install xdiagnose, run 'sudo xdiagnose' and turn on debug messages (the first checkbox). Then reboot, and do whatever you need to do to reproduce the blanking bug. Then, run 'sudo dmesg > dmesg.txt' and attach the dmesg.txt to the upstream bug report at https://bugs.freedesktop.org/show_bug.cgi?id=37526 ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Triaged => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/681054 Title: [i915gm] screen repeatedly goes black for a fraction of a second (two monitors detected?)
