I have two graphics cards: How do I just use the nVidia one?

Asked by Ryan Kaskel

As you can see below from the output of "lshw -c video," I have to graphics cards:

1) On board Intel
2) nvidia

I want X to use the nVidia card only, as the i915 Intel driver does not work in natty. I've tried installing the nvidia package from Ubuntu, to no avail, and the proprietary drivers from nVidia, also to no avail.

This is the error I see in Xorg.log:

[ 32.776] (II) LoadModule: "nvidia"

What can I do to fix this?

Thanks,
Ryan

I also am linking this question because the source of my issue is that the i915 driver doesn't work for me in kernels >= 2.6.38 https://answers.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+question/156082

All worked well in 10.10 (kernel 2.6.35)

Hi !

As you have a 'real' graphic card, I guess the easiest way is to disable the onboard card directly in the BIOS. There might be an option to do this.

The system will completely ignore the existence of the onboard card, and will rely only on the nvidia.

Can you help with this problem?
