How to Access Entire Desktop Remotely in Linux

There is no doubt that running X applications remotely is useful, but a truly killer feature is the ability to run the entire desktop from a remote computer on your local machine.
To do this, you need to use a feature called the X Display Manager Control Protocol (XDMCP), which is part of X. This protocol allows remote computers to access the GDM/KDM/XDM login program, which then gives access to the remote desktop. If you have a reasonably fast network connection—Ethernet speeds of 10-Mbit or greater are recommended—it is possible for a slow computer to be as responsive as a cutting-edge machine.This is possible because the local box is just a display device, like a television, and all the real work is done on the faster remote machine.
