Public bug reported:
Sometimes (usually once or twice a day) the screen goes completely off
and can't be turned back on. The rest of the system seems to be running
normally (not 100% sure about this, since I can't see anything). Only
way to restore it is hard reboot.
Not sure what triggers this, it seems quite random to me. Most of the
time when this happens (not always though), is when some app that uses
opengl is running.
I'm using ubuntu 12.04 with unity-2d. My graphics card is: "Intel
Corporation Mobile GM965/GL960 Integrated Graphics Controller".
