I'm having a problem with my monitor not turning off after the screensaver times out or, after the set time for the monitor to leave suspend and then off. I have checked, and +dpms is set with correct values. Xscreensaver is set also in advanced to turn off after 30 minutes. Have tried other times, but still does not work. ACPI in bios IS disabled, but I've never had to use that before to turn the monitor off.

Suggestions?
