Let me rephrase the question. Where are you ssh-ing the server from? A
Windows notebook? Mac? Ubuntu? Once you have that, you can search
Google on how to enable ssh forwarding when using that particular
CLIENT OS. Most linux distros that I know of already enable X
forwarding on server side, so it's usually just a matter of
configuring the client.

not much. Basically when you have that error unable to open display
"", and you're connecting via ssh, then most likely its ssh forwarding
problem. Sometimes it's as simple to fix as running "ssh -X" instead
of just ssh.
