How do I Downgrade Ubuntu from 12.04.3 to 12.04.2. I am doing this because having issues with my graphics drivers and screen goes blank some times.

Seems like downgrading 12.04.3 to 12.04.2 & Xserver is a solution to this problem.

Xorg.0.log file : http://pastebin.com/c3igdpbi

I tried below command didn't work though..! :( sudo apt-get purge linux-generic-lts-raring xserver-xorg-lts-raring

It showed below package not installed.!

Then I tried to manually install using below command,

sudo apt-get install --install-recommends linux-generic-lts-quantal xserver-xorg-lts-quantal libgl1-mesa-glx-lts-quantal

it showed - its already installed & to the latest version.

So, Is there any other way to downgrade ?

Thanks, Deena
