How to check if Nvidia drivers are installed and working properly on Ubuntu 12.04?

Asked by Tom Moore on 2013-08-02

I have a Nvidia GeForce 9500 GT 1gb pci card running on a 32 bit system. There are multiple drivers for linux and first I need to know which I should install. I tried one and after downloading, I tried to install and just got a white screen pop up. I am new to Ubuntu and don't know how to check to see the current driver for Nvidia. Please help, thanks.

Thanks, but I know how to get the driver from the Nvidia page. How do I then install that driver after it is downloaded on Ubuntu 12.04 and check to see if the device is working properly and that the integrated graphics are shut off?

Don't install nvidia drivers from their web page (because they'll be more difficult to upgrade/remove). Always use .deb packages where possible. If you need 319.32, at least use xorg-edgers PPA: https://launchpad.net/~xorg-edgers/+archive/ppa

As far as basic testing, install mesa-utils package an check the following commands:

$ glxinfo | grep vendor
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation

$ glxgears

If you run:

nvidia-settings

And you get no warning message, the driver is loaded and in use.

Can you help with this problem?
