On my system, the TCP and Unix-socket based connections for a given 
DISPLAY have the same cookie value.  I don't know if that's just the way 
I've configured X or if that's the way it's always supposed to be, 
though.  :)

However, I'd guess that's what causing the problem for you.  Perhaps 
it's a new X configuration or new *buntu configuration for X.  Chances 
are your local machine is using Unix sockets and the ssh session is 
using TCP.

Try:

export DISPLAY="localhost.localdomain/unix:0"

(or use mythfront/unix:0 ) in your script.
