As the topic suggests, has anyone had any experience of installing both the AMD SDK & libraries etc and the nvidia opencl on one PC?

I have a linux box based on debian 6 which is all setup for AMD mining.  For other projects I'd like to add a couple of nvidia cards too thus only run one PC for both but I wonder if it can be done.

The first fear I have is in order to install the opencl libraries etc I have to install the nvidia drivers which includes X drivers.... I don't want to ruin the machines current AMD functionality namely bitcoin mining.

Thoughts?

VM may be your only option. I don't know Linux really well, so I can't say for sure, but I know normally Nv, and AMD drivers don't play nice together.

On linux Ive not been able to get it to work, not with the proprietary drivers at least. One or the other card would work, but not both.
With windows (vista and 7), it does work effortlessly.

ah, ok chaps.... amazing, windows does it  Roll Eyes

I suspect its all the extra dross that comes with the binary drivers for linux that causes the issues.

Yep. its unfortunate, but it is what it is. I suspect using open drivers they would coexist more nicely, but for opencl thats not a realistic option yet.

And credit where credit is due; as much as windows gets wrong,  I was by shocked how easy it was to make this work on windows. You just plug the cards in, install both drivers, and I had ati running on one display and nvidia with nvidia drivers on my second display and i could game on either by just setting a primary display. Compared to struggeling with xorg.conf's for a full day and not getting anywhere, I found that impressive.
