[opensuse] Need help setting up vnc between two openSUSE machines

For years I have been using ssh, and when needed I used -X, but I thought it would be interesting to have a full remote desktop though. I know that SUSE has VNC, one the the members from a local LUG used my laptop to remotely connect to his desktop but I don't know how he did it and I don't know what I need to do to get it so I can connect to my desktop from my laptop and vice vera. -- "We must plan for freedom, and not only for security, if for no other reason than only freedom can make security more secure."
