This bug emerged for me when I upgraded my system (fresh install) from 12.04 to 12.10.
I have Acer Aspire 7720G (video card is GeForce 8400M GS; nvidia- experimental-310). uname -a Linux notebook 3.5.0-20-generic #31-Ubuntu SMP Wed Dec 5 13:29:58 UTC 2012 i686 i686 i686 GNU/Linux I thought that this bug is related to NetworkManager (https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1066484) as I often use bittorrent. But it appears even if I just left the computer on for a while. I'd noticed that if I log off (via GUI) first and then shut down (GUI too) from the greeter screen it shuts down properly no matters how long the computer is on. -- 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
