    What parameters are you passing when you SSH into the other box? Try
    either ssh -X username@remotehost or ssh -Y username@remotehost. If you
    pass -Y, you won't need to set up xhost. If you pass with -X, be sure
    to set the DISPLAY environment variable on the remote machine. I'd try
    just passing -Y first, it generally reolves the problems.
