X2Go enables you to access a graphical desktop of a computer over a low bandwidth (or high bandwidth) connection.

X2Go is a Remote Desktop solution, which some vendors vaguely call remote control.

With X2Go, you mainly access Linux computers. The Linux computer you are accessing is the X2Go Server.

You can connect from a computer running Linux, Windows or Mac OS X.


Traditionally, running programs with graphical output remotely has been donde using X-forwarding (-X or -Y options) via a SSH connection. While this method usually works well within a fast local network it is almost unusable when used outside the local network and the application is graphically demanding. X-forwarding is inefficient in that it needs to send a lot of information accross the network to an unknown display.

Two methods are often mentioned as alternatives to X-forwarding: X2Go and VNC. While both methods provide a way to share the graphical application across the network, X2Go turns to be, in general, more straightforward to use.
