I played a bit with this idea. The problem is, systemd-inhibit needs to
be tied to a running process, so I've tried this autostart file:

[Desktop Entry]
Name=systemd-inhibit
Comment=Inhibit systemd power events
Exec=systemd-inhibit
--what=handle-lid-switch:handle-power-key:handle-suspend-key:handle-hibernate-key
sleep 9999d
Terminal=false
Type=Application
NoDisplay=true
NotShowIn=KDE;

This has the unpleasant side-effect, that systemd-inhibit still keeps
running after the logout, since sleep is not killed during the logout.

An alternative idea was, to tie it to the dbus user session:

diff --git a/X11/Xsession.d/75dbus_dbus-launch
b/X11/Xsession.d/75dbus_dbus-launch
index af7ba49..afc19a9 100644
--- a/X11/Xsession.d/75dbus_dbus-launch

 if [ -n "$STARTDBUS" ]; then
-  STARTUP="$DBUSLAUNCH --exit-with-session $STARTUP"
+  STARTUP="$INHIBIT $DBUSLAUNCH --exit-with-session $STARTUP"
 fi


This way, systemd-inhibit is properly killed on logout. This does have
the downside of having to encode in a single file, in which desktop
environment it should be run or not.
