Computer shuts down monitor
Running Fedora 17 x64 with KDE. This is not new hardware and has worked fine in the past, but periodically the monitor shuts off during use. I mean the power light goes off, not even yellow. Tried other monitors, same result. Tried switching between a VGA cable and DVI cable, same result. Replaced the video card, same result.
The monitor may stay off for 5sec or 5hours no rhyme or reason. The computer still runs fine since its okay when the monitor comes back. I have noticed that when it gets turned off I can get it back by unplugging 120VAC and disconnecting the signal cable.
