|Description||Link a VNC and an X display together, simulating a multiheaded display machine with an X display and a machine with a VNC server running on its main screen to act as if they were two displays connected to one machine. When you move your mouse pointer off the screen in a direction of your choosing, the pointer will appear on the other screen instead.|
