Hmmm ... manual page of Xorg says:


      -keeptty
               Prevent  the server from detaching its initial controlling
               terminal. If you want to use systemd-logind integration you
               must specify this option.  Not all platforms support (or
               can use) this option.

... interesting fact is tath I see here

      [ 18039.023] (EE) systemd-logind: failed to get session: PID 31661 does
not belong to any known session

... in other words this option does not work as it should ... maybe something
has been disabled in the X server which does not do the controlling terminal
stuff.

Btw: Without the option an other error messages appears which shouts that
-keeptty option is required
