No display and Input signal out of range error in Linux?

Some times after the installation of linux(Debian based) one will end-up with the terminal and no GUI.  So, how can we fix it? Some quick checks 
1. Restart the gdm service by following command
$sudo /etc/init.d/gdm restart

2. Start the x-server
$sudo startx

3. Even after this if you are not getting the GUI and or got the error message like "Input signal out or range" then you need to edit your xorg.conf file.  This file is at /etc/X11/xorg.conf

i  ) Open the /etc/X11/xorg.conf file in your favorite editor with root privilege
ii ) Go to the section "Screen"  -> "Display" -> "Modes" put only the value "1024x768" and remove the all other values.  (If you know the correct resolution of your monitor the adding it is not a problem.)
iii) save the changes then again start the x-server(as like in quick check 2)

Hope this will help you.
Note: This is worked out in EduBOSS-2.0 and works fine.  EduBOSS is a linux distro for the school, college students which is derived from BOSS GNU/Linux.
