I have a setup where I have 2 NVIDIA Corporation GM204 [GeForce GTX 970] and a NVIDIA Corporation GT218 [GeForce 210] . I have the monitors plugged into the 210 and want to use the 2x 970s for GPU programming (CUDA) etc.

1) Is it possible to have 2 different types of NVidia Graphics Card running at the same time?

2) Is it possible to use the Nouveau driver for display (which works OOTB) and install a CUDA driver for the "non-display" cards?

3) If I don't want to use Graphics Drivers for the 970s what is the minimum I need to install for running CUDA?

I want a minimum install, as the last time I tried to update ubuntu I lost 4 days needing to rebuild everything from scratch, as I couldn't boot.

Running 16.04 LTS, brand new installation, nothing updated. FYI, apparently updating ubuntu causes my machine to not boot, so I would like to avoid apt-get update until I get my setup working.

On complete reinstall and then installing the NVidia driver, it appears that I can't have these specific graphics cards working together.

I have removed the GeForce 210 and just used the 2 GeForce 970.

Also, of super important note: for these I specifically could not use linux kernel 4.4 and on upgrading to the latest 4.7.5 and reinstalling the drivers from NVidia this worked fine.

NVidia: Driver Version: 367.44

Linux: 4.7.5-040705-generic
