If you would like to disable it you can go to

/etc/ssh/sshd_config

change
X11Forwarding yes
to no

At least this is how it's done on my version of mandrake.
enjoy!

Without going into a lot of detail, X is designed so that it can work as a 
tcp/ip client/server application.  Secure shell (sometimes) is configured to 
tunnel X connections by default.  Therefore, your application was running on 
the client machine and the machine that you were sitting on was acting as 
the X server.  Everything was done through an encrypted tunnel.  There is no 
need to do any remote desktop thingy configuration on Unix, since it usually 
runs X and it is by default usable as a remote desktop.
