I am using Ubuntu 10.04 x86 version.I have two video cards ( 1 integrated and 1 Nvidia on inter core-i5 processor with 3GB ram).Right now my display resolution is very poos as i cant use graphic card. I tried a lot of methods (including sudo apt-get remove nvidia*; sudo apt-get install nvidia-current) to install driver for Nvidia Geforce but failed. Here is output of lshw -c video

As shown in the output (width:64 bit), shall I install x64 version of Ubuntu to make drivers work? or what should i do to make them work ?

UPDATE I am following this post for installation. Whenever I execute sudo gdm-stop , i am not getting terminal or any screen. Even on CTRL+ALT+F2 i am not getting terminal screen(just a blank screen with no promt). How to go?

use 'jockey' not manual installation discussions. it's the 'supported' way of doing things – RobotHumans Mar 13 '12 at 18:19

The 'width' mentioned in the output addresses the width of the device, this has nothing to do with having 32bit or 64bit driver so using 64 bit ubuntu will make no difference to your video drivers.

Which Geforce graphics card do you have? If it is a hybrid card you may have some success using Bumblebee. Installation instructions here.

Thanks for explanation. I use Nvidia GeForce GT 520. – terty Mar 12 '12 at 15:44

No. You use the 32 bit binary driver for the best performance. Generally, jockey-gtk in the terminal is the way to install binary drivers on ubuntu. You could install x64 and the 64-bit driver...but you don't get 64 bit driver on 32 bit machines.

Thanks..I am reinstalling the driver and will update the results. – terty Mar 12 '12 at 15:45

Nope. These answers are wrong. You need to install bumblebee instead of NVIDIA drivers. Bumblebee is used with NVIDIA Optimus Graphic cards. Your output shows two video cards. Remove NVIDIA Drivers and install bumblebee.
