opencl support need sudo the first time to be enabled (NVIDIA)

Description

clinfo doesn't provide any informations about my NVIDIA Geforce 750Ti card, just only the Intel GPU.

I saw archlinux provides a package called nvidia-opencl with a file not present in Solus: etc/OpenCL/vendors/nvidia.icd

I need it to run darktable with opencl support. Maybe you could add this file to NVIDIA package ?

EDIT:

sudo clinfo provides info about the Nvidia card. And sudo darktable-cltest enable opencl support for darktable.

Then, I don't have to use sudo again to get the opencl support. I think it's not the correct way to have to run sudo the first time and it's a bug.

Try looking here (i.e. it already has the opencl loader):

/usr/share/OpenCL/vendors/nvidia.icd

Oh, right, it's here. Well I don't understand why darktable disable the opencl support :/

Strange, clinfo found my nvidia but only with sudo prefix.

And of course, sudo darktable-cltest is successful. Maybe a rights problem ?

@sunnyflunk I edit the report, after using sudo clinfo and darktable displays opencl support correctly. It's weird IMHO.

I just gave a try to clinfo and it worked without sudo (but I might have execute sudo clinfo a long time ago).
I suspec the problem to be at ocl-icd level since many applications are impacted
