Fedora 36 Silverblue, AMD Radeon 6900XT, ROCm installed.

When I start the boinc-client.service, I get `No usable GPUs found` and I'm unable to run GPU jobs. However, when I manually run `boinc` as my own user, it sees the GPU and I'm able to run GPU jobs. I don't understand why it can't see the GPU when `boinc` is run from the systemd service (which runs under the `boinc` user). I've compared the groups, and the only group my own user is in is `wheel`. I don't think `boinc` needs to be in `wheel`, but I tried that anyway and it still didn't change anything.

It can sometimes be a timing issue. BOINC detects GPUs by querying the drivers - and if the drivers haven't finished loading properly, they don't give a usable reply.

Try stopping the service before you reboot, and disabling it.

Then, after a reboot, wait until you have a usable desktop again. Then, enable the service, and start it manually. Works for me.

Thanks for the reply. The service was disabled by default upon installation. I never enabled it to start automatically. All my testing has been done with starting the service manually.

For now, I've resorted to using the Docker version of the client (boinc/client:amd), which is working with the GPU.
