Yes, there is a gdm group but my user is not part of it. I will test it
later since I cannot logout right now, but where did you find a
reference for this?

Searching for a reference myself, I found this not really related but
interesting (https://help.gnome.org/admin/gdm/stable/security.html.en):

"The only special privilege the "gdm" user requires is the
ability to read and write Xauth files to the <var>/run/gdm
directory.  The <var>/run/gdm directory should have root:gdm ownership
and 1777 permissions."

My /var/run/gdm has different permissions:

drwx--x--x  3 root gdm      60 May 23 10:19 gdm

I did not change or create this directory so it must be the default
created by the ebuild. Can anyone confirm that with these permissions
gdm works correctly?
