Package: systemd
Version: 239-7
Severity: important
Hi.
Since some systemd ugprade (unfortunately I don't remember which one it was
exactly, cause I
hit the problem only rarely)... when systemd-logind has been restarted, e.g. by
needrestart
after upgraded and I press the powerbutton, cinnamon shuts down immediately,
without asking
what I want to do (suspend, hibernate, restart, etc.) as usual.
Could as well be a bug in cinnamon itself but since it occured after some
systemd upgrade
I report it first here... please reassign if you think it's cinnamon specific.
severity important, as it can be quite problematic if one has e.g. written some
longer text
file and just wants to suspend the systemd... and then everything is gone as
the system
shuts down without any further request ;-)
Thanks,
Chris.

This was a systemd bug, not a Cinnamon one, and it has been fixed
upstream long ago.
The desktop takes a `block` inhibitor lock on
`handle-power-key:handle-suspend-key:handle-hibernate-key`
(csd-media-keys); when that lock is
lost, logind falls back to its default `HandlePowerKey=poweroff` and
shuts down immediately,
which is the symptom reported here. Restarting logind used to drop those
inhibitors — see
https://github.com/systemd/systemd/issues/11825, fixed by
https://github.com/systemd/systemd/pull/13143, merged in July 2019 and
released in systemd v243.
Buster shipped 241 and was affected; bullseye and later are not.
Retested on recent unstable (cinnamon 6.6.9-1, cinnamon-settings-daemon
6.6.4-1, systemd 261.2-1,
lightdm, X11): after `systemctl restart systemd-logind` the session
survives, the inhibitor list
is unchanged, and pressing the power button brings up the usual dialog
instead of powering off.
logind logs "Power key pressed short." and takes no action, as it should.
Closing accordingly. Note that the polkit part mentioned later in this
log (authentication being
required again after a logind restart) is a separate matter, considered
by design upstream.
