You realize that this is a Really Bad Idea (TM), right?

Are you running woody?  The X in woody disables TCP connections
directly to the X server; this seems reasonable, since most people I
know either never use remove X or only use X forwarding over SSH
(which doesn't need the random TCP socket open).  Try using a local
display, like :0.0, instead.

(And don't use xhost.  Really.  It's a massive security hole.  If you
must, 'xhost +localhost' is probably sufficient for your case.  A
shared xauth cookie is even better, though.)
