The default was changed from listen to nolisten about 18 months back, but
the -listen directive/argument is according to Alan Coopersmith at Xorg,
supposed to over ride it and turn it back on. Methinks the odroid
builders took advantage of that to get rid of 100k of object code. So I
have challenged the odroid people to actually make it work.

That server starts automatically. No clue it it shut down with
ctl+alt+del. No, its been hijacked to start a logout session for me.
The line that starts it, xinit/xsessionrc specifically says -listen tcp
as an argument for /usr/bin/X
