I use my Linux Mint 20.1 machine to do folding@home using the Ryzen 3400G, using just the CPU. I now want to try using the graphics part as well. This requires openCL. Having found that AMD now have drivers for Ubuntu 20.04 (which Mint 20.1 is based on), I thought i'd give this a shot. So i've installed https://www.amd.com/en/support/kb/release-notes/rn-amdgpu-unified-linux-20-40
/amdgpu-pro-install --opencl=rocr,legacy
And sure enough, I now have openCL installed. However, "Number of devices - 0"
$ clinfo

Here's where things get really weird. The folding@home control panel (FAHControl) can see the graphics chip, but NOT openCL!
15:26:39:WARNING:FS01:No CUDA or OpenCL 1.2+ support detected for GPU slot 01: gpu:10:0 raven [Radeon RX Vega gfx902]. Disabling.
I'm currently using kernel 5.8, but have tried 5.4 as well.

Can anyone figure out how I get openCL to see the graphics chip, and FAHControl to see openCL?!
I have already installed ocl-icd-opencl-dev
There is no difference between "clinfo" and "sudo clinfo".
I have already added the fahclient user to the video and render groups
sudo adduser fahclient render
sudo adduser fahclient video
I have already posted this query in the Linux Mint and folding@home forums, so will update here accordingly.
