Works here just fine - some quick troubleshooting questions:

1) what does "echo $DISPLAY" say on the login node ?

2) Can you run an xterm or xeyes or something from the
   login node of the cluster ?

3) Does it work if you use ssh -Y (instead of -X) to
   login to the cluster instead ?

cheers,
Chris
