Screen Saver - Power Monitor up

I have Suse 10.0 and under 9.3 -gnome I was able to determine the time when the screen has been idling to shut down the monitor on my desktop. Under 10.0 the option seems to be missing and can not find the place to enable this option. Does anyone know how to reenable this option or the package I am missing to do this? I checked the screen savor but the only option is to have the time when the screen saver is triggerd. There is no time to power down the monitor. -- Joseph Loo jloo@acm.org
