I have this problem, too, but on a ubuntu SERVER system. Today I upgraded from 10.04 to 12.04 and my machine does not power off most of the times. It's frustrating. With 10.04, there were no problems. I used this machine for nightly archiving data and for nightly backups of my server, with WOL enabled and automated shuitdown. It worked perfectly a very long time, until today.
I guess, this problem has nothing to do with any desktop environment. Maybe it is kernel-related? My system is an ASUS E35M1-I DELUXE. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/987220 Title: System does not power off reliably when "Shut Down" chosen from GUI To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-session/+bug/987220/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
