About TigerVNC
==============

Virtual Network Computing (VNC) is a remote display system which allows you to
view and interact with a virtual desktop environment that is running on another
computer on the network.  Using VNC, you can run graphical applications on a
remote machine and send only the display from these applications to your local
machine.  VNC is platform-independent and supports a wide variety of operating
systems and architectures as both servers and clients.

TigerVNC is a high-speed version of VNC based on the RealVNC 4 and X.org code
bases.  TigerVNC started as a next-generation development effort for TightVNC
on Unix and Linux platforms, but it split from its parent project in early 2009
so that TightVNC could focus on Windows platforms.  TigerVNC supports a variant
of Tight encoding that is greatly accelerated by the use of the libjpeg-turbo
JPEG codec.

All Platforms
=============

All versions of TigerVNC contain the following programs:

* vncviewer - the cross-platform TigerVNC Viewer, written using FLTK.
              vncviewer connects to a VNC server and allows you to interact
              with the remote desktop being displayed by the VNC server.  The
              VNC server can be running on a Windows or a Unix/Linux machine.


Windows-Specific
================

The Windows version of TigerVNC contains the following programs:

* winvnc - the TigerVNC Server for Windows.  winvnc allows a Windows desktop to
           be accessed remotely using a VNC viewer.

WARNING: winvnc is currently unmaintained and and may not function correctly.

winvnc may not work if the Fast User Switching or Remote Desktop features are
in use.


Unix/Linux-Specific (not Mac)
=============================

The Unix/Linux version of TigerVNC contains the following programs:

* Xvnc - the TigerVNC Server for Unix.  Xvnc is both a VNC server and an X
         server with a "virtual" framebuffer.  You should normally use the
         vncserver service to start Xvnc.

* vncpasswd - a program which allows you to change the VNC password used to
              access your VNC server sessions (assuming that VNC authentication
              is being used.) This command must be run to set a password before
              using VNC authentication with any of the servers or services.

* vncconfig - a program which is used to configure and control a running
              instance of Xvnc.

* x0vncserver - an inefficient VNC server which continuously polls any X
                display, allowing it to be controlled via VNC.  It is intended
                mainly as a demonstration of a simple VNC server.

It also contains the following systemd service:

* vncserver@.service - a service to start a user session with Xvnc and one of
                       the desktop environments available on the system.
