Vino does not have the invitation mechanism present in KRfb, but the other features
are basically the same. Vino does permit multiple simultaneous connections, and
there is no reset time after a disconnection. Vino ignores the client??™s request for an
exclusive connection??”so there is no way to ???bump??? an existing connection as you
can with other VNC servers (which is useful if you forget to disconnect from one
location and later connect from another).
14.15 Using the VNC Extension to the X.Org
Server
VNC is also available as an extension for the standard X.org server. This extension
makes the image on the X display available to VNC clients; unlike KRfb or Vino
(which are started by the session manager), the VNC extension is present whenever
the X server is running, which means that you can authenticate using the display
manager through VNC and start a new session. The server extension also provides
better performance.
RealVNC includes a loadable X module for the X.org server; it installs as /usr/lib/
xorg/modules/extensions/libvnc.so.
