GPU shown as not supported

desert1701 · Post by **desert1701** » Mon Nov 10, 2025 8:23 am

Hello people,

after installing Mint on my machine last week, I wanted to rejoin the folding effort, and installed FAH. When I used windows, the GPU was being utilized just fine, but now it is shown as not supported.

Here's the log output:

I get the same result on the release version 8.4.9 and am posting here, as it was mentioned in this thread, that GPU detection might work better in beta.
I have tried restarting FAH with

Code: Select all

sudo systemctl restart fah-client

to no avail.

You should start with this guide for AMD GPUs on Linux : viewtopic.php?t=43222

Thank you, following that guide for Mint fixed it.
Reminder to self: Don't just google for the problem, also think for search terms for the solution
