Silently fails to restart shutdown without message when user logged in on virtual console

[Frederik Himpe]

When a user is logged in on a virtual console (tty1), then choosing restart or shutdown in lightdm greeter does not restart or shut down the system. I would expect a message to be shown stating that restart/shutdown is not allowed because a user is logged in on tty1.
