I'm installing the boinc client (V7.24.1 in the repo). The CPU computation works fine, but I think it would be better to use the GPU as well.
I installed the mesa-opencl-icd package and the table randomly froze.
As it turns out only when the bonc client detects that there is GPU in the machine and starts using it.
When I remove the /etc/OpenCL/vendors/mesa.icd file, OpenCL works (clinfo:https://justpaste.it/dyl1h), but the boinc client no longer sees the GPU.
I also tried to set the RUSTICL_ENABLE=radeonsi environment variable, but this did not lead to any results either.
What could be causing the GPU usage to kill the desktop?

Don't use the Mesa OpenCL drivers. Use the official AMD ones.

Thank you, it works now!

I was happy too soon. The AMD driver(for ubuntu 22) does not fully work on ubuntu 24. Although it starts GPU counting after installation, it won't start the operating system after reboot(something went wrong, and a sad computer picture).
I also tried putting the driver back on ubuntu 22, which the driver came up fine. It works fine after reboot. But clinfo does not see the device, and bonc does not find the GPU.

I finally found a combination that worked. If I don't run the graphics manager (boincmgr), it seems to use the GPU, and the desktop doesn't freeze.
