I cannot concure on the conclusion that it is related to closed-source drivers exclusively. I have the problem on 2 machines with Intel graphics, and not a single proprietary driver installed. They only shut down completely and switch the power off in 50% of the shutdown attempts. In general all my machines (I oversee more than the two which won't switch the power off) take ages to shutdown since Precise. I recenlty upgraded one machine to Quantal: it does shut down, but I can basically get a coffee until it finaly powers off. Up to Oneiric everything was fine: quick shutdown, and relyable poweroff.
Although this bug is declared "fixed", none of the above "fixes" have had any impact on the weird behavior at shutdown. -- 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
