nvidia and nvidia-340xx simultaneously

Greetings.

Is it anyhow possible to install both nvidia and nvidia-340xx drivers simultaneously?
The problem is that two GPUs are present in the system: an old NVS Quadro 295 and a GTX 970. NVS support was dropped after 340 driver version.
The plan was to use NVS as the host primary video card and leave GTX for the CUDA calculations.

Thanks

I don't think you're able to do this as there are conflicting files each version writes out (including nvidia.ko).  Someone correct me if I am mistaken.

As graysky said you would need to change the module names both the file names and references to the name in the module itself and possibly adjust userspace tools to work with the new module name so theoretically possible but none trivial.

Alkersan,

If the GTX is only used for CUDA, there may be a possibility .

install the nvidia-340xx drivers, except  opencl-nvidia-340xx .
Also install opencl-nvidia .

If you're lucky, everything needed for cuda on the GTX is in the opencl-nvidia package.
(It's that way for amdgpu-pro ).
