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...
