The modified form of this latest version of Ubuntu ( Ubuntu 12.04 Precise Pangolin ) is more better than than the Ubuntu 11.10. Everything was fine and working normally but I found Brightness problem in it.
The brightness of my laptop cannot be increased or decreased as like in Windows . The main problem was the battery wouldn't last longer like that while using in Windows. The indicator will show the brightness changing but the result is same, there will not be any changes in the brightness.
Here is a solution to decrease or increase the Brightness in Ubuntu 12.04.

Follow the few steps listed below and you may get rid of these problem:
* First open the terminal and type this code:
xrandr -q | grep " connected"
* Then you will get the output as:
LVDS1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 331mm x 207mm
* Now to change the brightness use the following command in the terminal and you will get the changes.
xrandr --output LVDS1 --brightness 0.5
You can increase or decrease the Brightness of your laptop by changing the values 0.5 to any other. You can check using 1.0, 0.9.etc. But if you give the brightness 0.0, the screen will be black and cannot see anything.
