I'd like to replace gnome-screensaver with xscreensaver. I'd tried: $ killall gnome-screensaver $ xscreensaver $ gnome-session-save but alas, when I log out and back in I find that gnome-screensaver is running and xscreensaver is not. I'm looking for a more elegant solution than deleting the gnome-screensaver executable and copying xscreensaver in its place, although that solution is looking more and more attractive. Thanks.
In order to install xscreensaver, you must install xscreensaver-base, xscreensaver-extras, xscreensaver-gl-extras. Then you must remove gnome-screensaver by "yum -y remove gnome-screensaver". When you go to "System-Preferences-Screensaver", you will find that the gnome-screensaver is no longer there. I hope that this helps.
