X can even receive commands from the keyboard or mouse. That way the game can have a clue on what is happening! You will often hear X being called a server and the reason for that is simply because the way the applications send commands to it is through sockets.

For that reason the applications are also referred to as clients many times. We can see that X is running as root and has PID An other important thing is to notice the :0 which is called display in X jargon. A display is essentially:. Now there is a variable in Linux that is used whenever we run a GUI program. I get :0which means we use display 0. Notice however that this says nothing about which monitor we use.

This makes sense since if you are running 2 or more monitors on your Linux you still have the same environment variables in both of them.
