So GDM automatically figures out whether to add -nolisten tcp or
-listen tcp depending on what X server is installed when GDM is built.

See:

https://bugzilla.gnome.org/show_bug.cgi?id=750026

and

https://git.gnome.org/browse/gdm/commit/?id=3f59fa0da5168451898db63e51e312ce894af0c1

You probably just need to make sure you have your xserver devel
package installed at
GDM build time.
