Gnome-screensaver

[Don Springall]

How do I switch my system back to x-screensaver. I prefer some of the 
screensavers provided there more.
Gnome screensaver seems to have only seven screens.

I have the following screensavers installed:
xscreensaver-base-4.23-1
gnome-screensaver-debuginfo-2.13.5-4
xscreensaver-extras-4.23-1
gnome-screensaver-2.13.5-4

Also will gnome-power-manager work with xscreensaver ?
