I can't figure out how to get my screen saver to turn on after a timeout period greater than 1 minute. Everytime I set it in display preferences and click "apply" it defaults back to 1 minute. I even tried specifying it in policy editor, no luck.
Open regedit.exe and edit the registry key manually. The key you are looking for is in HKCU\Control Panel\Desktop and is called ScreenSaveTimeOut, double click on it and specify a value in seconds, the default should be 60 seconds.Reboot after you have changed it.
