21.6 Summary

For situations where remote access to individual Ubuntu desktop applications is required as opposed to the entire GNOME desktop, X11 forwarding provides a lightweight solution to remotely displaying graphical applications. The system on which the applications are to appear must be running an X Window System based desktop environment (such as GNOME) or have an X server installed and running. Once X11 forwarding has been enabled on the remote server and a secure SSH connection established from the local system using the X11 forwarding option, most applications can be displayed remotely on the local X server.
