I found a possible solution to this bug. It has something to do with the auto login function in the user management from Unity. When activated it cannot shutdown anymore. Also disable the auto login is not possible anymore.
What I did: $sudo gedit /etc/lightdm/lightdm.conf remove the line: autologin-user= YOUR USERNAME Restart your computer with: $sudo shutdown -h now After that I had a system that worked normally again. -- 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/838792 Title: "Restart" logs out, even when there are no other people logged in To manage notifications about this bug go to: https://bugs.launchpad.net/indicator-session/+bug/838792/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
