Open a terminal (alt+f2, 'terminal') and type this [code]sudo yum install xscreensaver-extras-gss xscreensaver-gl-extras-gss[/code] EDIT: there was a small typo in the above which I've now corrected (the opengl screensavers weren't properly installed) Then type: [code]gnome-screensaver-preferences &[/code] and select a decent screensaver, some of the OpenGL ones are stunning - but not recommended on battery power :) (Note that you have to reboot the first time you change the screensaver to have the screensaver loaded, after that there is no need to reboot if you change the screensaver using gnome-screensaver-preferences)
