Sometimes ssh -Y works when ssh -X doesn't.  Over time I've started
using ssh -Y as it always works.

If the server is setup correctly, it will not allow you to ssh as
root, you'll need to ssh -Y as yourself and then su -.  When you use
the su command you might loose the DISPLAY variable, in this case
simply re-establish it and all should work.

If you workstation is Linux, you have an X-Display running.  If it is
Windows, you can use Cygwin as your X-Server.
