Configuring FAHClient to use my AMD RX 580 on Ubuntu 18.04

[LavaDrop]

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.

[foldy]

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

[LavaDrop]

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.

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

[John_D]

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.

[LavaDrop]

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.

[Paragon]

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).

[Joe_H]

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.
