Description Arne Stäcker 2012-12-04 17:42:42 UTC 
I'm running Gentoo and systemd 196.

When I run 'su' in a terminal under KDE and switch to root, my normal user and user's session looses the "active" state and switches to "online". And so my normal user looses all device file permissions. After exit the su mode, the state is still "online".

Last know working version was 193. Could't test intermediate versions because of bug #55656.

Before 'su':
$ loginctl show-session 1

Comment 1 Pavel Procopiuc 2013-01-10 14:40:20 UTC 
The same bug affects me too. I've done investigations and found out that the bug was introduced in systemd-196 by the commit 978cf3c75fbd94fd0e046206ada6169b35edd919

You can view it online: http://cgit.freedesktop.org/systemd/systemd/commit?id=978cf3c75fbd94fd0e046206ada6169b35edd919

Reverting this commit in systemd-196 sources fixes the problem.
Comment 2 Arne Stäcker 2013-01-11 11:02:44 UTC 
Just tried the same, but then I run again into bug #55656 as the commit fixes the bug.
Comment 3 Arne Stäcker 2013-01-19 13:19:41 UTC 
No change with 197. When I have time, I will do a git-bisect.
Comment 4 Arne Stäcker 2013-04-15 07:59:09 UTC 
Works again with systemd 199 and above. Thanks to all developers.
