Folding @ Home Linux Mint Nvidia GPU

[MCDELTAT]

Can anyone produce docs on how they set up Nvidia GPU calculations on Linux Mint 19.x or Ubuntu 18.04+ ? I can't seem to find anything helpful.

I'm currently getting the error in System Info "OpenCL Not Detected: Failed to open dynamic library 'libOpenCL.so': libOpenCL.so: cannot open shared object file: No such file or directory."

At first, FOHControl wouldn't even detect my GPU because I normally install the drivers from the Graphics-Drivers PPA that Steam/Proton recommends. So I had to remove the Nvidia-440 drivers, reboot, then install the Nvidia-435 drivers that come stock from the Driver Manager application on Mint. FOHControl then found the GPU but then says that it can't find OpenCL. Here's the packages I have installed that seem relevant:
aaron@aaron-Mint-Rig:~$ dpkg --get-selections | grep nvidia

xserver-xorg-video-nvidia-435            install


aaron@aaron-Mint-Rig:~$ dpkg --get-selections | grep opencl
ocl-icd-libopencl1:amd64            install
ocl-icd-opencl-dev:amd64            install
opencl-c-headers                install



opencl-index and cuda-index are both set to -1

When I set opencl-index to 0 it tricks into thinking it has a valid one, but then the calculations fail.

Likely need the OpenCL development packages

 

ocl-icd-opencl-dev

 

and a reboot

 

see Linux HOWTO in my sig

 

the 440 drivers should be fine

Already had them installed, see the last section of my installed packages.

Just solved it though, I just reinstalled the fahclient software again and it detected my OpenCL packages and started working immediately. So for future reference with anyone, install the Nvidia Drivers and ocl-icd-libopencl1 and ocl-icd-opencl-dev packages before installing the client.

Made my day because I had spent probably 2+ hours on it when my it's my main rig that already had everything minus OpenCL installed anyways.

I currently have this issue. I have reinstalled the client, reinstalled the drivers, reinstalled ocl-icd-libopencl1 and ocl-icd-opencl-dev packages, but the 2nd GPU is not listed with Open CL. I'm at a loss, as the 960 is working perfectly.
