Take the 2-minute tour ×  I'm having a problem with notebook
screen on Ubuntu 13.04(for what i remember it happened on 12.10
too), sometimes( i think at least, mostly when playing games)
the monitor just powers off, but the system seems to be running,
and there's no way i can turn it on again so i have to do a hard
reboot. My video card is a Second Genaration Sandy Bridge(Intel
HD 3000, i965). Anyone knows something about how can i debug
more and/or solve it?  share|improve this question add comment
