Hello Mantas, thanks for your reply!

Right, I understand that. But that doesn't mean that *always* have a $DISPLAY. So simply having user units that start with systemd --user does not work: If the first login is on a VT or through ssh these would all fail, and if you then actually login on the DM nothing would restart them. That could be helped a bit with a ConditionHasEnvironment=DISPLAY or something such, and an xinit.d script that restarts them. But this can all be achieved through some good/bad hacks, my main issue is still that you can't bind those to the system unit with the correct lifecycle -- session-*.scope. > I can start this with "systemctl --user start xeyes@${XDG_SESSION_ID}", > > but this will hang off user@1000.service instead of session-*.scope > > and thus it will not be stopped once the X session gets logged out. > > > > Most X11 clients will exit as soon as the X server goes away, no? They do, but you get failed units and scary error messages, and this happens *after* the X session is already gone -- thus no way for them to gracefully shut down. > `systemctl --user import-environment DISPLAY` seems to work well enough.
