    wdm is a replacement for xdm and has it's own configuration directory,
    similar in nature to xdm but called wdm.

    There are different ways to achieve your desired result, you should find
    an appropriate place in /usr/X11R6/lib/X11/wdm/wdm-config to add the
    -nolisten tcp option to the server line similar to the xdm option you
    tried already.

    For gdm, the process is similar the line to start the X server is in
    gdm.conf and would look like command=/usr/X11R6/bin/X -nolisten tcp.

    There are other places this can be done, but these options might be
    easiest for you. You might also want to make sure you have XDMCP turned
    off also otherwise you'll be listening on udp 177 too.
