Press Alt+F2 and type gconf-editor
In gconf-editor navigate to /apps/gnome-screensaver
To change the time before the screensaver comes on change the value of "idle_delay".
To change the type of screensaver between none ("blank-only"), normal ("single") and random ("random") edit "mode"
To change the screensaver used ("single" only) edit "themes". The value has the form of "screensavers-<screensaver_name>".
To find the names of your available screensavers open your file browser and navigate to "usr/lib/xscreensaver".
Alternatively you can list the names in the terminal with
