[opensuse] Can't suspend (hibernate) anymore when a second user (root) is still logged in
Hello, A change from earlier this year made suspend (hibernate) fail with "Permission denied" when I have a root terminal open (i.e. I'm logged in with KDE as a normal user and I did a "ssh root@localhost" in a terminal). Note that I understand that the risks involved, so please refrain from starting a discussion why I shouldn't do this. All I want to know is how I can disable this check; I don't care who else is logged into my computer (I might even have a remote login from the server in the basement), I want it to hibernate without question when I'm telling it to - I don't want to climb into the basement in the middle of the night just to be able to suspend.

Ah, the old "it's obvious for me" fault :-) Sorry for that. It happend for openSUSE 13.1 and 13.2. I patch my system roughly every week. Regards, -- Aaron "Optimizer" Digulla a.k.a.

I hibernate using "pm-hibernate" command in a terminal opened as root, so I bypass those checks, I believe. (I had some other problem when trying to hibernate as plain user in xfce, so I use that trick routinely). A year ago the session would refuse to hibernate if a local user had a session, but not a remote user. I pointed this out. Now they detect both situations, instead of none, as I asked. The situation can be specially dramatic on a laptop with low battery. By the way: an ssh session can survive hibernation: depends how long it stays dormant. At worst, you could get a question asked what to do. Or pop a warning to remote users about what is going to happen. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

That might work but I'l prefer to disable those checks: 1. I click the Hibernate button in kshutdown 2. The screen is locked 3. The screen blankers are starting up 4. I hear a "beep" - KDE is trying to show a notification that Hibernate isn't possible ("Permission denied") 5. I have to move the mouse/press shift 6. Log in again 7. Kill the root terminal (Ctrl+D sometimes hangs?) 8. Hibernate again.

Do you know what they changed? Regards, -- Aaron "Optimizer" Digulla a.k.a. Philmann Dark "It's not the universe that's limited, it's our imagination.

Nope. Could be code. :-( Maybe policykit. Have a look here: [Bug 846914] 13.1 RC1 - when hibernating, the system requests root's password. [Bug 856773] User is asked for root's password to hibernate, but not for shutdown or reboot. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

At least in 13.2 hibernation is handled by logind which distinguishes between three cases - hibernate, hibernate with multiple sessions and hibernate with active inhibitors. The former does not require authentication for active session, other two - do. bor@opensuse:~> pkcheck --action-id org.freedesktop.login1.hibernate --process $$ bor@opensuse:~> pkcheck --action-id org.freedesktop.login1.hibernate-multiple-sessions --process $$ polkit\56retains_authorization_after_challenge=1 Authorization requires authentication and -u wasn't passed. bor@opensuse:~> I do not know in 13.1 KDE was already integrated with logind.

Try suspending from root
