The way that X works is the same as the way any network program works. You have a server of some description (in this case, the X display server) which runs on a specific machine, and you have X clients (like firefox) that try to connect to that server to get their information displayed.Often (on 'home' machines), the client and server run on the same box and there's only one server, but X is powerful enough that this doesn't need to happen.
It was built with the server/client separation built in from the start.This allows you to do such wondrous things such as log on to your box (in text mode) halfway around the planet, tell it that the display server is the box you're currently on and, voila, the windows suddenly start appearing locally.In order for a client to interact with a user, it needs to know how to find the server. There are a number of ways to do this. Many clients allow the -display or -displayoption to specify it: xeyes -display paxbox1.paxco.com:0.0Many will use the DISPLAY environment variable if a display isn't specifically given.
You can set this variable like any other: DISPLAY=paxbox1.paxco.com:0.0; export DISPLAY # in.profileexport DISPLAY=paxbox1.paxco.com:0.0 # in your shellDISPLAY=paxbox1.paxco.com:0.0 firefox & # for that command (shell permitting)The first part of the DISPLAY variable is just the address of the display server machine. It follows the same rule as any other IP address; it can be a resolvable DNS name (including localhost) or a specific IP address (such as 192.168.10.55).The second part is X-specific. It gives the X 'display' (X server) number and screen number to use.
The first (display number) generally refers to a group of devices containing one or more screens but with a single keyboard and mouse (i.e., one input stream). Please do NOT try to set $DISPLAY manually when connecting over SSH.If you connect via SSH -X and $DISPLAY stays empty, this usually means that no encrypted channel could be established.Most likely you are missing the package xauth or xorg-x11-xauth. Try to install it on the remote machine using: sudo apt-get install xauthor sudo apt-get install xorg-x11-xauthAfter that end and restart your SSH connection.

Don't forget to use SSH -X so that X Window output is forwarded to your local machine.Now try echo $DISPLAYagain to see if $DISPLAY has been set automatically by the SSH demon. It should show you a line with an IP address and a port.
