Screensaver not working in Ubuntu

Hey everyone,

I have a screensaver set to turn on in Ubuntu, but it does not work. It doesn't work in both KDE nor GNOME. The only clue that it is trying to work is after 10 minutes of being idle (when it should turn on)...if you move the mouse or press a button, the entire screen refreshes, sort of like coming out of screennaver, but there is no screensaver being visualized.

Any ideas?

Thanks!

do other opengl applications work, and if you have it available what is the output when you type 'fglrxinfo' in the console?

Well...I think some of the 3D screensavers use OpenGL, and all screensavers work when I try using the "Test" button.

fglrxinfo says "command not found"
