i was having this problem too. but xset s off didn't fix it for me. i had to put this in my xorg.conf file:
Section "ServerFlags" Option "blank time" "0" Option "standby time" "0" Option "suspend time" "0" Option "off time" "0" Option "screen blank" "0" EndSection
then i had to restart X. now, the screen never goes blank! gnome-screensaver kicks in! hope that helps!
