I would like to use openCL for darktable and have installed a nvidia 730 GT in my PC. However, I cannot get clinfo to show a platform, so I was hoping that someone here could give me a hint. What I found so far is that a version mismatch between drivers might be a problem (https://stackoverflow.com/questions/54668169/sample-devicequery-cuda-program).
Removing everything and starting with installing cuda first however seems to install some dependencies that prohibit me from installing any nvidia drivers afterwards (I guess).
sudo mhwd -i pci video-nvidia-470xx
at least shows an error, as video-hybrid-intel-nvidia-470xx-prime is already installed. I cannot remove it as it would break nvidia-utils which are required by cuda.
Any help and hints are appreciated!
Since Cuda is optional, I suggest you start over, first remove Cuda and whatever dependencies it installed with it, install your nvidia driver using manjaro hardware configuration tool, then reinstall cuda.
Yes, that’s what I figured as well (so far :D). I just installed CUDA as I thought it might be needed to have openCL after it did not work initially.
I removed everything and installed the drivers as described here: Configure NVIDIA (non-free) settings and load them on Startup - Manjaro
As a graphics card it is working now. Afterwards I installed opencl-nvidia as described here: GPGPU - ArchWiki
Unfortunately, clinfo still shows no running platforms.
Out of curiosity I installed intel-opencl from AUR as this supports my CPU. This results in a platform which is found by clinfo.
Do I have to activate the opencl platform somewhere?
In a hunch I changed my kernel from 5.15 to 5.10 LTS in hope for better driver support, but no luck.
These are the nvidia packages that I have currently installed (pacman -Q | grep nvidia):
clinfo still shows no openCL platform available.
Someone on reddit found the solution: The version of opencl-nvidia did not match the driver versions. Removing opencl-nvidia and installing opencl-nvidia-470xx from AUR solved the issue.
