you don't run the X server process on the remote system, the X Server runs on the system with the video card in it - which is generally the workstation/pc/laptop you are looking at. the programs running on the remote server are the X Clients, and you tell them where the server is by setting the DISPLAY variable. Generally you also enable SSH X11 tunneling on the remote server by setting it in the ssh_server.conf file and restarting sshd, and when you ssh into the server you use the -X switch on the ssh command to tell the ssh client to create an X11 tunnel through your ssh session.
