OK, we have to figure out where the "-nolisten tcp" comes from.

AFAIK, it is not even necessary to remove the "-nolisten tcp" here if
you are starting Xorg via [xkg]dm.

Hmm, on my system that is enough to make Xorg listen to port 6000 (after
I restart kdm). However, looking at /etc/init.d/kdm I get the impression
that in some cases you also have to edit /var/run/kdm/kdmrc to remove
ServerArgsLocal.

If that does not help then I would like to see the output of

pstree -aAc | grep -B2 -A2 '[X]org'
