restart impossible when a remote ssh session is running

[Emmanuel Thomé]

(assigning to lightdm, although it's broader than that. Not clear which component is to blame exactly).

Let X be a laptop running ubuntu 12.10. It's an x86-64 cpu for that matter, but no one cares.

Assume an ssh server is running on X, and someone is logged in via ssh from another machine Y to machine X.

Now if X is showing a lightdm login screen, there is no way the ``restart'' button (from the top-right menu) can work. It is simply ignored. There is no message either.

If some user is logged on X, and he opens up the top-right menu and goes to ``restart'', one of two things may happen.
  - If the remote session is under this very user, then the session is killed, and the computer restarts.
  - If the remote session is under another user (root, for the situation I tried), then the user's session is nuked, but the computer does not restart, and returns back to the lightdm login screen.

I find this quite irritating. Ssh sessions to my laptop may happen. When I have physical access to it, I would like to be able to restart/shut down the machine without having to either do a dirty shutdown (5s press) or hunt manually for ssh session and kill -9 them, or ctrl-alt-f1, root login, and reboot.

I would conceive it if someone considers it's ''dangerous'' to kill incoming ssh sessions. Not that I share this opinion, but I imagine it may exist. If so, would it be possible, please, to have a dialog box like ``yes, I mean it'' if the system decides it's perhaps unwise to proceed to reboot ?

Best,

E.

Added consolekit to the affected packages because I believe this is the package responsible (maybe with policykit?) for denying shut down or restart based on who's logged in.

Status changed to 'Confirmed' because the bug affects multiple users.
