I don't see anything incriminating in dmesg, /var/log/messages or /var/log/Xorg.0.log. I'll switch the system to boot to runlevel 3 so I can see if X is spewing something to the first alternate console that isn't getting written to the log file. Anyone have other any suggestions as to diagnosing of fixing the problem?
Are there any DPMS options set in your xorg.conf ? What is your video card/monitor and what driver are you using in X ?
Another thing to check is see if DPMS is enabled as an extension by your setup:
xdpyinfo |grep DPMS
should return "DPMS"
I have to explicitly set my monitor power saving to off on my laptop otherwise the screen has a high likelyhood of not coming back on after turning off. Toshiba says it's a known behavioral issue with multi core laptops. Happened under XP as well. Yay for screen burn in.
