Nvidia and Nvidia legacy together

Hi,

I have a GTX 560ti and a 9500GT installed in my computer.
I'm using the proprietary Nvidia drivers which work fine with the 560ti but not with the 9500gt.

Running

lshw -numeric -c video

tells me the 9500gt is UNCLAIMED.

Looking at the wiki it says I should use the nvidia-340xx package for this legacy GPU.

The problem is when going to install the drivers I get

:: nvidia-340xx and nvidia are in conflict. Remove nvidia? [y/N] 

How can I get nvidia and nvidia-340xx to be installed together so I can use both cards?

Thanks

Re: Nvidia and Nvidia legacy together

I don't think you can use both at the same time. First to all, kernel module for both has exactly the same name. There can be only one nvidia.ko.

Re: Nvidia and Nvidia legacy together

What would the best way to get the two cards working together?

I could use Nouveau on the second card but can't install OpenGL support as it conflicts with Nvidia OpenGL support

Re: Nvidia and Nvidia legacy together

Again, the only way of having two nvidia cards on a proprietary driver working together is if they use the same diver: nouveau won't work, because of KMS (you can't use nvidia driver if nouveau is loaded, installing nvidia driver blacklists nouveau.)

Have managed to get Nvidia and Nouveau working together by removing the blacklist and creating a file in /etc/modules-load.d with

nvidia
nouveau

So that nvidia first picks up the GTX 560ti then nouveau will pick up the other card.

Only issue I'm facing now is this bug https://bugs.launchpad.net/ubuntu/+sour … ug/1326688

Re: Nvidia and Nvidia legacy together

Not sure how it worked, I was under impression that it will still be a conflict. A puzzle to investigate.
But am glad it worked for you.
