Shutdown/Restart from gdm fails silently with 2+ users logged in

[Darren Worrall]

Binary package hint: gdm

When more than 1 user is logged in, selecting 'Restart' from the power menu on gdm does not do anything and returns no error. When restarting from within a session when more than 1 user is logged, a dialog is thrown asking for elevated privileges to confirm the action, but this does not happen while in gdm.

Steps to reproduce:

Login as user1
Switch back to gdm and login as user2 as well
Switch back from user2 to gdm and select restart

What I expected to happen

Login as user1
Switch back to gdm and login as user2 as well
Switch back from user2 to gdm and select restart
Dialog popped asking for credentials of an admin user
System restarts

I'm pretty sure this happens with shutdown as well, I will test that now and amend this report

Just to confirm this is the same with shutdown as well. Tested in my D820 laptop and in a Virtualbox VM.

Thank you for your bug report. The issue is an upstream one and it would be nice if somebody having it could send the bug the to the people writting the software (https://wiki.ubuntu.com/Bugs/Upstream/GNOME)

I added the affects LTSP to this bug. If you think it is bad to shut the machine down with 2 users logged in how would it be with a computer lab of 25 or 50 users? I think that for LTSP this should have a much higher priority than low. After having this happen to me another 2 bugs

cause local applications not to run on the clients that were still running and not logged out at server shutdown.

I bug report has been filed with LTSP for this too.

Closing LTSP task, nothing LTSP upstream can do here.
