Question OpenSUSE 11.1 x86_64 Can't Turn Off Display Power Management


Hello, I've got a rather annoying problem with OpenSUSE 11.1 x86_64, I can't turn off the display power management! I've tried from the KDE 3 and 4 settings as well as GNOME, and finally YaST2. There's nothing in monitor's controls (the buttons on the monitor itself). The actual GUI controls in KDE/GNOME/YaST2 work (as opposed to being grayed out or disabled) and the system doesn't complain when I hit apply/OK, but every time I disable display power management, I wait about 15 minutes and sure enough, the screen blanks. I've checked and made sure the screen saver is disabled, I've looked for a setting to change in the YaST2 sysconfig editor and the kernel settings app, but can't seem to find anything. The only other thing I can think of is to try the acpi=off kernel boot option. I'd rather not resort to that. Anyone know if there is some super secret hidden setting somewhere that might be overriding everything else? Could this be some sort of ACPI incompatibility issue? I've gone over the system logs looking for any possible explanation or clue and have found nothing.

Excellent suggestion, It worked! I wonder why the GUI controls failed to have any effect.
