GNOME Bugzilla – Bug 495602
Slider values for inactivity can not be set below 11 minutes.

Maybe more power can be saved if those values (especially the value for blanking the screen) can be set below 11 minutes. Maybe the sliders should allow values starting with 1 minute. Other information:
You can resolve this by lowering the "time to make the computer idle" setting in Gnome-Screensaver-settings. You can only set the sliders in GPM to numbers bigger than the idle setting in GSS. I know it seems silly, but GPM only finds out that the system is "idle" once you exceed that time.
