Running the above two lines, and then rebooting, got my Nvidia GeForce GTX 1660 Ti recognized by FAH. I had to then manually create a GPU slot. Thank you!

I have the same exact issue with my 1070 GTX on Fedora 31. I have tried the nvidia drivers from both the RPMFusion and negativo17 repos. I installed just about every opencl package I could find by running "dnf search opencl". I hope someone can help me figure out how I can fix the issues so I can use my GPU for folding. Here is my latest log:

Have to say that while I like the idea of sharing unused resources for research, it needs to be seamless for the volunteer provider.

Thanks for working through the install issues; I'm impressed by both your skills and the others that helped resolve the issues. That points per day looks pretty close to what I am seeing on a similar Nvidia card.

Does clinfo work (may need to install it.) If it doesn't, I would try different Nvidia drivers - perhaps from Nvidia themselves and not in-distro. For mine, I install Cuda and use the drivers they provide.

I have 2080 RTX Super and finally got OpenCL to work with FAH:
installed packages
dnf install opencl-utils opencl-filesystem opencl-headers opencl-utils-devel
dnf install ocl-icd ocl-icd-devel

Crucial part to get Fedora 31 NVidia OpenCL to work is
dnf install xorg-x11-drv-nvidia-cuda xorg-x11-drv-nvidia-devel
and removal of
dnf erase mesa-libOpenCL pocl
if you happened to install those. (Edited pocl here as well, thx to aclater.) With current FAHClient there can be only one icd at the time in /etc/OpenCL/vendors/ folder.

Other installed NVidia packages are
org-x11-drv-nvidia-libs-440 kmod-nvidia akmod-nvidia-440 nvidia-persistenced-440

So I did a bit of digging around with this today, because we have had several folks who have been unable to get OpenCL working on Fedora. What I've found is that FAHClient seems to experience some issues if there is more than one OpenCL platform on the host. Through some trial and error, it looks like FAHClient attaches to the first OpenCL platform on the host, regardless of whether it matches the name of the GPU Vendor. I have seen mesa-libOpenCL as well as POCL create this issue. On Fedora 31 - you want to make sure the following packages are present (at least these don't seem to interfere):

ocl-icd-2.2.12-6.fc31.x86_64
ocl-icd-devel-2.2.12-6.fc31.x86_64
opencl-headers-2.2-5.20190205git49f07d3.fc31.noarch
opencl-utils-1-10.svn16.fc31.x86_64
opencl-filesystem-1.0-10.fc31.noarch
clinfo-2.2.18.04.06-3.fc31.x86_64

You want to make sure the following are not installed:
mesa-libOpenCL-19.2.8-1.fc31.x86_64
pocl.x86_64

clinfo should reveal only a single platform installed:

Code: Select all

clinfo | head
Number of platforms                               1
  Platform Name                                   NVIDIA CUDA
  Platform Vendor                                 NVIDIA Corporation
  Platform Version                                OpenCL 1.2 CUDA 10.2.141
  Platform Profile                                FULL_PROFILE

The client should be updated to either allow selection of the appropriate OpenCL platform (via name or index) or should use the OpenCL platform which matches the name of the GPU.

*** I use the RPMFusion nonfree Nvidia Driver ***
