With gnome3 in Fedora 15, in gnome-control-center I have set my computer to automatically suspend after 30 minutes. However, the computer never automatically suspends (the screen does turn off and lock though). This used to work in previous versions of gnome. I'm not sure if this is gnome-power-manager, gnome-session, gnome-control-center or some other thing... Let me know what info I can provide.
Moving to gnome-power-manager. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
