And, of course, for reference purposes, Kazu always seems to know
what he's talking about... :) This is probably a good summary
and should be FAQ-ified.

There may be conflict between getty and xdm. On which vty are you
running xdm?
AFAIK, there are four ways to start xdm and avoid conflicts with getty.
1. Specify xdm in /etc/ttys. If you want to run xdm in ttyv3, you write:
ttyv3 "/usr/X11R6/bin/xdm -nodaemon" xterm on secure
2. Run xdm from /etc/rc.local (or other rc* files).
if [ -x /usr/X11R6/bin/xdm ]; then
(sleep 10; /usr/X11R6/bin/xdm) &
fi
It is essential to add "sleep N" for proper operation. You may need
to experient in order to find an appropriate value for N in your
configuration.
3. Another way to run xdm from /etc/rc.local (or other rc* files).
if [ -x /usr/X11R6/bin/xdm ]; then
/usr/X11R6/bin/xdm
fi
You need to explicitly specify a vty in which to run the X server
by modifying /usr/X11R6/lib/X11/xdm/Xserver.
:0 local /usr/X11R6/bin/X vt4
The above example will run the X server in ttyv3. Note that the X
server counts vtys as vt1, vt2, vt3..., whereas FreeBSD uses the
notation ttyv0, ttyv1, ttyv2,...
4. Specify the X server in /etc/ttys.
ttyv3 "/usr/X11R6/bin/X vt4 -query localhost" xterm on secure
_Remove_ the X server from /usr/X11R6/lib/X11/xdm/Xserver.
_Add_ localhost to /usr/X11R6/lib/X11/xdm/Xaccess.
Start xdm from /etc/rc* as:
if [ -x /usr/X11R6/bin/xdm ]; then
/usr/X11R6/bin/xdm
fi
Hope this will give you some ideas.
