Same with me Ubuntu 12.10. Following some updates Restart and Shut down from the graphic interface no longer work bringing up to the login screen. I have several graphic interfaces and they all fail - Unity, Gnome Shell, xfce and lxde. You go to the login screen when you select Power Off or Restart from the graphic menu. On the login screen these options do nothing. Terminal "sudo poweroff" and "sudo reboot" commands both work fine, but it is rather disturbing having to open a terminal and type my password each time I want to turn off or reboot my machine. None of the suggestions in this thread worked for me.
This issue seems to persist in Ubuntu for more than a year now. Anyone having any ideas how to fix it? I can't believe it doesn't bug you having to power off using the terminal every time. It should be noted that it worked initially on 12.10 and got broken only following an upgrade, -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-session in Ubuntu. https://bugs.launchpad.net/bugs/838792 Title: "Restart" logs out, even when there are no other people logged in Status in The Session Menu: Invalid Status in Unity Foundations: Invalid Status in “gnome-session” package in Ubuntu: Confirmed Bug description: Trying to restart the computer from within a unity session causes the session to log out, instead of actually restarting the computer. 1.
