Is OpenCL compatible while open source nvidia driver is installed?

I'm trying to run Davinci Resolve and running into an issue.  I have an older nVidia 580 graphics card with 3GB of RAM.  I'm using nvidia-390xx drivers.  When I launch Davinci Resolve it gives me the option to use CUDA, but that doesn't work... and I'm guessing it's because I'm using the open source driver and CUDA is proprietary.  The Arch wiki does not recommend using the proprietary driver because of something to do with kernel updates.

So it seems my options are to install the proprietary driver and proceed, or install the open source nvidia driver and opencl along side of it... if this is possible.  I don't really know how openCL ties in with the driver, or if they're mutually exclusive or what.

If you are using nvidia-390xx you are using the proprietary driver and you might want to elaborate on what the actual issue is you are having, or what "doesn't work" actually means.

Right, my mistake.  Here's the problem, on launch I receive:

DaVinci Resolve encountered GPUs with unsupported compute capability.  Would you like to update the DaVinci Resolve GPU processing mode in Hardware Configuration?

Please ensure that your DaVinci Resolve hardware meets the minimum requirements for the selected GPU processing mode.

If I choose to update, I see:

GPU processing mode: CUDA
GPU selection mode: Manual
Selection: GeForce GTX 580 (2.9GB)

Here's the output of the terminal when I'm doing this:

Re: Is OpenCL compatible while open source nvidia driver is installed?

Well that doesn't contain much of value, FWIW cuda and opencl-nvidia-390xx are installed? And you probably don't want to run this as root, why are you running this as root?
