I had the same bug, and in my case, I manually stopped the plexmediaserver (which I had manually installed) before trying to shutdown. This solved the problem. My guess is that there is a daemon process running as a user that gnome-session sees as being logged in. I'm not sure how gnome-session determines which user sessions are safe to terminate, but stopping this process let my machine shutdown and reboot normally.
I'm not really sure this is a bug with gnome-session so much as it is a bug with other packages starting daemons that show up as actual users. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
