I can confirm that changing to the virtual terminal also stops working. This may be caused by the binary nvidia driver for the GeForce 8600M GT graphics card in my PC. I am currently using version 295.49 of the driver but both installed drivers have the fault. I have used Ubuntu on this PC for several years without this problem so this bug was introduced with 12.04.
I have tried "$ sudo poweroff" from a terminal and it fails. Shutdown from an remote ssh login also fails. Currently I do not have any safe way to shut down the system. -- 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
