Using a single computer is not enough today, we are in need to use one more of it for testing even for a small modification we make to. Hence virtualization plays a vital role.
In the world of virtualization you may come / came across VNC (Virtual Network Computing). For more info google “VNC”
I am going to show some simple steps to be followed while configuring VNC for debian desktop.
Installation of VNC server is like cutting piece of cake
$ sudo apt-get install vnc4server
You can choose a geometry for viewing,
$ vnc4server -geometry 1024x768 -depth 24
This will prompt us to set a password and will verify once.
Your password will be available at ~/.vnc/passwd
To start a new server that runs on your machine
New 'boss:1 (cot)' desktop is boss:1 Starting applications specified in /home/cot/.vnc/xstartup Log file is /home/cot/.vnc/boss:1.log
It tells that newer server has been started with respective details for tracing.
To Kill the process (stop VNC server)
$ vnc4server -kill :1 Killing Xvnc4 process ID 16592
To access remote machine (server) you need to know HOSTNAME of server(machine)
On remote machine enter the below command
$ xvnc4viewer boss:1 VNC Viewer Free Edition 4.1.1 for X - built Mar 10 2010 21:40:13 Copyright (C) 2002-2005 RealVNC Ltd. See http://www.realvnc.com for information on VNC.

A new window will open up by holding the terminal of server (machine), you can’t access any GUI, but it is rather very much helpful for creating, running, debugging new applications.
