Hi!
I've been scratching my head for several days trying to figure out the Linux client and it's configuration.

I've tried several suggestions:

Add FAHClient to video group
Verify I've a correct installation of drivers (AMDGPUPRO) and OpenCL (clinfo)
Correct expert flag setup script put incorrectly because the installer is expecting the client to be properly configured (gpu=false flag)
Change opencl index from -1 to 0

However, the client still states it can't find my OpenCL device and produces Bad Work Units (it does detect the actual GPU, though).

This is the log:

I can run GPU work units on BOINC.

Try that first:
sudo apt-get install ocl-icd-libopencl1
sudo apt-get install ocl-icd-opencl-dev

Thank you, however it made no change at all. GPU still stuck on Ready.

You need the AMD proprietary OpenCL driver: https://www.amd.com/en/support/kb/relea ... fied-linux

I have the proprietary driver installed and properly configured.
BOINC detects and works with my GPU.

Since the client looks set up ok, try this:
set the client to medium in FAHControl.
Are you running two clients, one for your CPU and one for your graphics card.

Posted: **Wed Mar 18, 2020 1:58 am**

FAHControl is set to medium.

BOINC is only running CPU tasks because Rosetta doesn't use GPUs. I was running SETI and then they announced they were putting the program on hibernation, so I paused SETI. I set it up to use 8 threads at 50% CPU time.

I've run into this with my RX 480s and RX580s. You've probably done everything right. There's a weird permissions issue, where the FAH Client just can't access the open CL libraries.

See this thread...it's a long read.

viewtopic.php?f=81&t=31293&start=15

In summary, the key bit is a workaround based on this other thread

viewtopic.php?f=74&t=31096

Basically you need to tweak the startup script for the client (/etc/init.d/FAHClient), changing the username from "fahclient" to "root". The client can then see Open CL devices and fold correctly. This seems like a problem unique to AMD GPUs on Linux, since Nvidia GPUs work fine (once open CL is installed).

For some Linux distros you may need to add the fahclient username to be part of the video group. I recall coming across that posted at one time. I personally have not needed to do that, the newest Linux setup I have currently is running on Ubuntu 16.04.
