Public bug report changed: https://launchpad.net/malone/bugs/24307 Comment: I noticed that I have a process 'x-session-manager' rather than 'gnome-session' running in my process list: >> ps x | grep session 16346 ? Ss 0:00 x-session-manager when gdm hangs, sending this process a SIGHUP makes my gnome session end. Is this perhaps related?
