I have a Samsung SyncMaster 940BW display with a sceensaver that keeps interrupting my work. Their manual says its totally controlled by the operating system and cannot be changed in Samsung's display menu. In PCLinuxOS2009 it shows that its disabled in Control Panels, Peripherals, Display, Power Control. The other screensaver is also disabled int Control Panels, Appearance & Themes, Screen Saver. But the PowerSaver just keeps kicking in every 15 minutes or so. Any suggestions?
