[School-GNU-Linux] setting up virtual screen

Hello All,

Some old computers/monitors support only 800x600 resolution. If you
want to run an application which requires 1024x768 resolution in such
system, you can use the virtual screen facility of xserver.

To set up that, you need to edit the file: /etc/X11/XF86Config-4 and
add a line in the screen  section as follows:

Section "Screen"
       Identifier      "Default Screen"
       Device          "Intel Corporation Intel Default Card"
       Monitor         "LCD-MONITOR"
       DefaultDepth    24

SubSection "Display"
               Depth           24
               Modes           "800x600" "720x400" "640x480"
               Virtual 1024 768

       EndSubSection

add the line virtual 1024 768 just after the modes line

and restart the Xserver (/etc/iniit.d/gdm restart) or Ctrl+Alt+BkSpace
