Xvnc is the X VNC (Virtual Network Computing) server. It is based on a standard X server, but it has a "virtual" screen rather than a physical one. X applications display themselves on it as if it were a normal X display, but they can only be accessed via a VNC viewer - see vnc...
An alternative to the remote X server solution is to run a pseudo-X server such as the X Virtual Frame Buffer, or XVFB. Actually, XVFB is an X server. That is, XVFB processes X Window System requests and sends responses using the same network protocol as the standard X server. The ...
