I haven't been following this thread, but from the Subject I would guess
that there's may be problems with the client machine's ssh_config file, the
target machines sshd_config file, or the command being executed.

To enable X11 forwarding on the client side on recent versions of openssh,
either the ``ssh -Y'' command or the ssh_config options ``ForwardX11'' and
``ForwardX11Trusted'' must be set to ``yes''.

On the server side, the sshd_config file must have ``X11Forwarding'' set to
``yes'' to allow any client X11 forwarding.

On older versions of openssh, the ``-X'' option was sufficient, but now
``-Y'' is necessary (although ``-X'' might work if ``X11Forwarding'' is
``yes'' in the ssh_config file).
