It happens randomly, the screen goes blank (like it went to sleep) and the power button goes yellow (like it went to sleep), but I know it is not asleep since I can shutdown the machine by pressing the power button (to activate the on-screen 'restart/sleep/cancel/shutdown' menu and press enter to cause the machine to shut down.
Something is telling the screen to go to sleep and nothing I do will wake it back up (short of a restart by any means necessary). I have repaired permissions, repaired disk, turned off ALL power saving settings, and waved a rubber chicken over the machine while chanting some voodoo gibberish I picked up from a James Bond flick on Spike. Why is the screen going blank on me? How can i determine if this is hardware or software (since it never does this on 9.2.2, only X.2.8, it could be how X interacts with the hardware...).
The problem is more nuisance than anything else, but a permanent fix is desired.
