Hi,
I am newbe to linux and ubuntu. I have a confusion, How to find out graphic card vendor of my mother board. I did following,
In terminal I issued
Code:
sudo lshw -c video
and got following:
Code:
*-display               
       description: VGA compatible controller

I think vendor is nvidia, right? If yes what drivers should I install for ubuntu 12.04 ?

After installing ubuntu, sound and graphics working without installing any additional drivers. But will performance increase if I install proprietary drivers ?

In software center I found the following:

NVidia binary X.Org driver ('version 173' driver) - not installed,
NVidia binary X.Org driver ('current' driver) - not installed,
NVidia binary X.Org driver ('version 96' driver) - not installed,
Additional Drivers (jockey-kde) - not installed,
Additional Drivers (jockey-gtk) - Installed.
Which of these drivers should I install ? Please help.

Many thanks.
