Installing nvidia drivers on ubuntu 12.04.2 LTS

Nvidia Installation

Hit Ctrl + Alt + F1

sudo apt-get update
sudo apt-get install linux-headers-generic

sudo apt-get dist-upgrade

--------------------
If your linux was not installed from a cd, but instead from a stick, do this:

sudo nano /etc/apt/sources.list

Comment all the first lines that have a "cdrom" in the beginning.

Save and exit with Ctrl-O + Enter and Ctrl-X (Exit)

sudo apt-get update
---------------------

Now ...

sudo apt-get install nvidia-current-updates
sudo nvidia-xconfig
reboot

You are done.
To make sure the driver is properly installed, on the system hit the "system key" and type Additional Drivers, verify if the nvidia drivers are properly in use.


Be happy and enjoy your new drivers for gaming on linux =) !
