I think I have come to the CRUX of the problem.

The DISPLAY variable is being set to something like "lonewolf:10.0" when
I SSH to the box.

This only works when my box (that I am SSH'd into) can resolve that name
(via /etc/hosts) to the correct IP.

I have just tested this and if I manually set the DISPLAY variable to
the "<IPoflonewolf>:10.0" it works fine.

So this brings me to a new question which I don't see the answer to in
the man pages:

How do I get dhclient to update the /etc/hosts file with my DHCP
assigned IP address??
