VNC stands for Virtual Network Computing. It is, in essence, a remote display system which allows you to view a computing `desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.

It is implemented in a client/server model. This package provides a client for XWindow, with this you can connect to a vncserver somewhere in the network and display its content in a window. There are vncserver available for X and for Win95/NT.

The difference between the xtightvncviewer and the normal vncviewer is the data encoding, optimized for low bandwidth connections. If the client does not support jpeg or zlib encoding it can use the default one. Later versions of xvncviewer (> 3.3.3r2) support a new automatic encoding that should be equally good as the tightvnc encoding.


High CPU usage in X when VNC client is connected

Various causes between X versions and display driver may cause this issue. Below solutions attempt to fix:

Add parameters in x11vnc command line

If you are using x11vnc, you may try different parameters, one at a time, to see if it fix the issue




Create / Specify display driver in /etc/X11/xorg.conf

This will force X to use the VESA display driver, which is slow for local display but works great for remote connection.
