when systemd-logind is active it will by default react to power events
and execute the actions configured in /etc/systemd/logind.conf.
A desktop environment usually wants to handle such events on their own.
E.g. they want to lock the screen on suspend or hibernate or show a
confirmation dialog before shutdown when the power button is pressed.
For that, the desktop environments are supposed to grab an inhibitor
lock  for the events it wants to handle.
There is a command line tool systemd-inhibit  which you can use to
inspect currently active locks and it can also be used to grab a lock.
As a desktop environment, you can either stick a call like
in your session start script or you let your desktop session component
responsible for power management grab that lock. This is e.g. how it's
done in GNOME, where gnome-settings-daemon is grabbing the lock and in
KDE, where PowerDevil, does the same.
There exist patches for xfce4-power-manager to use the logind inhibit
API and also use the suspend/shutdown/shutdown/reboot D-Bus API provided
by logind. Please not, that a working suspend/shutdown/shutdown/reboot
requires functionality from systemd, as logind will forward those
request to the running systemd process.
The patches are available at , specifically
You can choose to only apply a/ and continue to use upower, even when
systemd is active. But as you are already aware, the suspend/hibernate
functionality is going to be removed from upower 1.0, so it makes sense
to include b/ and c/ as well.
If you have further questions, please ask.
