DESCRIPTION

Xwnc is a free X server for Virtual Network Computing (VNC). It provides all the capabilities of a X server, but does not connect to a display for itself. You need to write your own client to view and control the applications that run on the server (see http://insitu.lri.fr/~chapuis/metisse/ for more information and an example).

EXAMPLES

Xwnc :1

Invoke Xwnc on display :1 at localhost.

OVERVIEW

Many options are available to Xwnc in order to give as much flexibility as possible to the user. Most of the options are standard options for X server, and Xwnc provides a few additional options dsigned for its special purpose.
