Under Breezy, the 'Switch User' used gdmflexiserver. This gives you a list of already open displays (and hence logged in users).
So yes, I agree that this is a bug in the Gnome-session logout screen logic in that it doesn't query currently logged in users. -- 'Switch User' button from 'System/Quit' should behave exactly like 'Switch User' from gnome-screensaver https://launchpad.net/bugs/47005 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
