Ubuntu – How to install the most stable & latest nvidia driver in 12.04


I have recently installed Ubuntu 12.04 alongside Windows 7.

After completing the Software Update process, I thought that my nVidia drivers also would have been updated, but after restarting the system and checking the version, it still was showing as version 173.14.35. I have nvidia geforce 7025 / 630a integrated in my ASUS motherboard

Can someone tell me how can I update my drivers with the most latest and stable release?

Also when searching a lot I went through couple of pages which showed something like PPA. Can someone please explain me what is a PPA?

I don't know your graphics card model, so my answer is based on assumption.

Its looks like your graphics card is old and use legacy 173 driver from nvidia.

If so, for your graphics card, there was no development done from nivida in terms of version. So whatever you have is the best and latest driver. If you forcefully install new drivers it will cause lag/crash to your system.

A ppa is a package bundle provided by 3rd party (meaning any other than Ubuntu official). Adding a ppa and installing an app/driver from it means you will be receiving updates for them when the ppa owner updates a page.

Basically ppa s are for easy install and update process.

See more details from this discussion What are PPAs and how do I use them?
