Bug Description

Binary package hint: gnome-session

There does not seem to be a way for root to cleanly shut down a particular gnome-session.

Obviously restarting gdm works, but that kills all sessions. In my environment, users
share machines and we have lots of "switch user" activity. What I'm really trying
to do is to automatically clean up those sessions that are left and forgotten:
otherwise they build up and eventually every user is logged onto every machine.

Apparently, you need to send a message on the dbus to gnome-session, but getting the session ID
for a particular user/process ID isn't trivial. One would really like to be able to send
a signal to gnome-session, and have it gracefully shut down whatever it can.
(Obviously, I can do kill -9, but that can cause trouble if gnome-session needs to do clean-up
activities.)

So, _basically_, the bug is that gnome-session ignores all signals. It shouldn't. There are perfectly
good reasons for responding to signals.

Thanks for the report, it has been some time without any response or feedback in this bug report and we are wondering if this is still an issue for you with the latest release of Ubuntu the Natty Narwhal, May you please test with that version and comment back if you're still having or not the issue? Please have a look at http://www.ubuntu.com/download to know how to install that version. Thanks in advance and sorry for the late response.
