So you will need to turn off your normal users screensaver and be fine with everyone having the same screen saver and only being able to change it when you are logged in as root.
On top of all that. You will need to put up with doing this nasty hack... which can be hard for the linux noob. If you want to see a screensaver while knowing you need a password to access the computer why not just use xlock? While logged in just open a term (or creat a icon) and type in xlock. A screen saver will popup and when you move your mouse it will ask for a your user password... then if you like it just man xlock and read how you can configure it.
ok, Thanks for the info, What you said explains what I needed to know. I dont want to have it running all the time for root.... I just wanted to be able to have the screen saver runnign while at the login manager in init 4.
