Sounds like you aren't being authorized.

This commit seems relevant: http://cgit.freedesktop.org/systemd/systemd/commit/?id=89f134406af6

Feel like reverting it and testing?

Also, need the output from 'systemd-loginctl'

i'll do my best to get to it, if i'm not capable to test it i'll let you know tomorrow evening

then i'm unfortunately 2 or more days without internet

tested with systemd lxdm and xfce with systemd 42 and no issues at all, everything keeps on working fine

i can try again with kde and patched systemd this evening, maybe kde is doing something weird

Reported upstream: https://bugs.kde.org/show_bug.cgi?id=293978

lxdm + kde systemd reboot; shutdown ok
systemd-loginctl:
SESSION UID USER SEAT

0 sessions listed.

lxdm + xfce systemd reboot; shutdown ok
systemd-loginctl:
SESSION UID USER SEAT

0 sessions listed.

kdm + kde systemd reboot; shutdown fail
systemd-loginctl:
SESSION UID USER SEAT
c1 1000 ike seat0

1 sessions listed.

kdm + xfce systemd reboot; shutdown ok
systemd-loginctl:
SESSION UID USER SEAT
c2 1000 ike seat0

1 sessions listed.

ok i found enough space on my virtual machine to install kde and narrowed a little bit down

kdm + kde is a fail

Same problem here, also with kdm as display manager and the upgrade to systemd 42-1 (subsequent upgrade to systemd 43-2 did not help).

systemd-loginctl:
SESSION UID USER SEAT
1 0 root seat0
c5 1000 eric seat0

Reverting the commit didn't help. Please note that a consolekit error pops up in the log when kdm appears (polkitd(authority=local)[326]: Unregistered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session1 (system bus name :1.28, object path /org/kde/PolicyKit1/AuthenticationAgent, locale en_US.UTF-8)) and that everything works properly when kdm is started manually, not through the .service file. (# /usr/bin/kdm -nodaemon tty7).

This consolekit log does not look like an error. When the session is opened I have:

polkitd(authority=local): Registered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session6 (system bus name :1.99 [/usr/lib/kde4/libexec/polkit-kde-authentication-agent-1], object path /org/kde/PolicyKit1/AuthenticationAgent, locale fr_FR.UTF-8)

and when the session is closed:

polkitd(authority=local): Unregistered Authentication Agent for unix-session:/org/freedesktop/ConsoleKit/Session6 (system bus name :1.99, object path /org/kde/PolicyKit1/AuthenticationAgent, locale fr_FR.UTF-8)

Shutdown and restart also work well when kdm is started manually, not through systemd.

You're right, that's most probably a regular message. I took "unregistered" for an adjective, not a verb.

Disabling pam_systemd makes restart/shutdown work.

thx for the workaround ("solution") Łukasz

remove pam_systemd from
/etc/pam.d/kde
/etc/pam.d/kde-np

did work fine

so is this then a packaging bug in kdebase-workspace ?

is sshd also affected ? i saw that /etc/pam.d/sshd also had a reference to pam_systemd

This is strictly related to greeters...

Not really a bug, persay, just lacking support.

Please post the output of 'systemctl status dbus.service' from a non-working session. You should expect to see polkitd running...

None of this is really interesting... pointing more at something broken in KDM upstream (my setup using lxdm works fine).

From a broken _and_ working session, the exit codes/output of:

pkcheck --action-id org.freedesktop.login1.reboot -u --process $$
pkcheck --action-id org.freedesktop.consolekit.system.restart -u --process $$

Make sure this is done from a fresh terminal and not something like a leftover tmux/session session of a previous login.

both simply return 0 (kdm + kde, with modified /etc/pam.d/kde{,-np} which results in working shutdown and reboot)
system is freshly started

should the output be different ?

Yes... I'd expect that they return 0 when it works. The interesting case is when it _doesnt_ work.

both return 0 ( just changed the /etc/pam.d/kde{,-np} back, cant reboot, cant shutdown)

You'll need to figure out what it is that KDM/KDE is sending to dbus to try and reboot/shutdown, then. You can use dbus-monitor.

dbus-monitor stops before kdm restarts

any suggestions what to look for, the only things i find in the dbus-monitor log is logout in both cases

when i find the time i'll look into this lateron, i have no more time now

monitor the system bus from a console session as root.

Attached is the log from dbus-monitor --system, starting with logging in via kdm and ending with (failed) restarting.

is there a need for more logging ?

any news on this bug?

Feel free to lean on KDE upstream (bug report was linked earlier in this FS). There's no packaging bug to fix here.

This commit fixes this bug.

And this is in testing...
