Ok… I have learned a bit by now.

The "'/run/user/0/dconf': Permission denied." is a different problem not
related to my initial problem of GDM not showing.

The initial problem was not Metacity theme installed. As soon as I have
installed one the GDM starts properly from systemd.

The "'/run/user/0/dconf': Permission denied." and related errors are 
showing only when I stard GDM manually from the root shell. This is
a design 'feature' of pam_systemd – it always uses the uid of the user
who initially logged in. So GDM won't start properly from a user login
session. Even if that user is root.
