The X Windows System (also known as X11, X, and X-Windows) is a windowing system, common on Linux and Unix-like operating systems. X provides the basic framework for a windowed GUI environment. Drawing and moving windows on the display as well as interacting with the keyboard and mouse are handled by X.

SSH X Forwarding
While using SSH to access a system running the X Windows System, it is possible to have any X windows generated by the remote system appear on the local machine. To connect to the system at the IP address 10.0.2.41 with X forwarding, enter the following command:
developer@ldc:~# ssh -X user@10.0.2.41
Other than the -X option, the procedure for logging in is the same as that listed on the System Login Page.
To verify that X forwarding is enabled, the following command may be entered:
user@emac-oe:~# xclock &
This will open a small analog clock in a window on the host machine. The window can be closed after verifying the correct functionality.
