Did you log in to the remote machine with ssh -X ?

From the man page:

-X      Enables X11 forwarding.  This can also be specified on a per-host basis in a configuration
             file.

             X11 forwarding should be enabled with caution.  Users with the ability to bypass file permis-
             sions on the remote host (for the user's X authorization database) can access the local X11
             display through the forwarded connection.  An attacker may then be able to perform activities
             such as keystroke monitoring.

Hope this helps.

Regards,

Gavin.
