And one other thing to check (in addition to the X11Forwarding) is
whether or not you're trying to ssh via a login shell or a regular term
console; if you're using a login shell, your $DISPLAY won't be set on
the client machine anyways.

In the terminal from which you'll be initiating your ssh session, check
and see if $DISPLAY is set; if not, open a non-login shell and try it
again.
