Using X Window System for GUI

The X Window System software can be used to provide a graphical user interface (GUI) for computers running UNIX and Linux operating systems.

When using X Window System from a remote system for example, to access the Configuration Tool, you must set up the DISPLAY environment variable to allow the application to display its windows on that system.

On the display system (that is the one that displays the windows), enter the command:
xhost +appl
where appl is the network name of the system being used to run the application.
On the application system, before you run the application, enter the command:
export DISPLAY=disp:0.0
where disp is the host name or IP address of the system where the windows are displayed (followed by a colon and the display id, which is normally 0.0). The application windows are then displayed on the disp system.
