*Only reproducible with xorg-edgers PPA*
I have an external monitor attached on the display port of my laptop ( HDMI is
not possible since optimus drivers are not complete) and randomly the monitor
freezes. I can move the mouse but I cannot click on anything and the keyboard
does not respond either.
This effect lasts for a few seconds will background music to continue playing
and then returns to normal. When returning to normal operation I get a report
of an apport-gpu-error-intel.py.
In the kern.log there is now a line
[drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU hung
