https://bugzilla.novell.com/show_bug.cgi?id=726969 https://bugzilla.novell.com/show_bug.cgi?id=726969#c0 Summary: Prevent halting/restarting from gdm when switching users Classification: openSUSE Product: openSUSE 12.1 Version: RC 1 Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Major Priority: P5 - None Component: GNOME AssignedTo: bnc-team-gnome@forge.provo.novell.com ReportedBy: badshah400@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:7.0.1) Gecko/20100101 Firefox/7.0.1 At present the situation is that if an user A locks his session, anyone else (say user X who also has physical access to the computer) can still opt to "switch user", go to the gdm login screen, and then, from there choose to halt/restart the system without so much as a warning about another session running in the background. This is a big inadequacy in my opinion and perhaps also a security risk. I suggest that the halt/restart buttons be disabled completely and not shown on the gdm shell when it is presented to a user upon choosing to "switch user" while another user session is logged in. Halt/Restart "works" from the gdm screen even if multiple users are logged in. Related upstream bug: https://bugzilla.gnome.org/show_bug.cgi?id=662813 Reproducible: Always Steps to Reproduce: 1.Log in as an user 2.Lock screen 3.Select Switch User from the locked screen to reach gdm login screen 4.Select restart/halt Actual Results: System halts/restarts even when another user session is in progress (and locked) Expected Results: Halting/restarting from the login screen should not be allowed when a user is logged in and has his session locked. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So if the system annoys you with password prompts when trying to shut down you simply can force the system off the hard way. You can also switch consoles and press ctrl-alt-del to reboot any time without authentication. Therefore my opinion on the matter is that restricting shut down for the local console doesn't make sense by default. However, it would be nice if gdm could warn that there are still other users logged in and offer not not shut down. That way prevents accidental shutdowns but does not hinder you to shut down the machine if you really need to. Reassigning to gdm maintainer. [I noticed an inconsistency between consolekit and logind privileges though, will adjust logind privileges to also allow shutdown for multiple sessions] -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

His seems like a great idea.

To me, this is really an upstream bug. What we can do in openSUSE is to make sure the policies for halt/restart when there are more than one logged in users require a password, I guess. But that's all until upstream does something a bit more elaborate (and you already filed the bug for this upstream). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
