If you add "-v" to your invocation of ssh then it will almost certainly
tell you exactly why the forwarding is not happening.  It's probably the
case that your target machine has:

X11Forwarding no

in its /etc/ssh/sshd_config file.

Change that no to a yes, and then do "/etc/init.d/ssh reload".  Log out
of the target, then back in and you should find that "echo $DISPLAY" now
displays something.
