Nvidia will be restricted in most ubuntu Versions. This is also a hurdle for people who like Desktop Effects. Installing Nvidia is not a big task Just requires some series of steps to do.

Procedure:

1. Download the required driver from Nvidia website. Due to Nvidia's UDA, you cant get drivers exactly for your Video card.

2. Ctrl + Alt + F1.

3. Execute sudo /etc/init.d/gdm stop to terminate X-Server.

4. You will be dropped to a non-graphic console.

5. Login to the console and navigate to the Folder where you downloaded the Nvidia Driver.

6. Type sh .run

7. It will guide you to an interactive installation process.

8. In some cases, the installer will opt for compiling a version for your device when it fails to find a kernel module. Accept the offer in such case.

9. After the installation is complete, reboot your pc with sudo reboot.
