It could be that if DISPLAY is set before you run ssh -X then ssh won't
change it.  Try unsetting DISPLAY first.  Also, make sure there's
nothing in your profile/bashrc stuff on the remote host that messes with
DISPLAY.

If you do this your X session is no longer tunneled through SSH, and
thus not secure.
