x2x or other program

I should have said: "VNC is painfully slow, and insecure too (unless
encapsulated inside a SSH tunnel)". VNC is slow by itself, and even slower
when tunnelled through SSH since SSH imposes some performance penalty due to
encryption (and compression). I suggest you trying out NX/FreeNX as it's
free and open.

I have just installed NX and it is really good. I have both Ubuntu and
Windohz clients with an Ubuntu server running.
