Hi Gang

Thanks for the pointers. I had a bit more time to investigate this morning. In the end discovered that the Oibaf drivers (these are bleeding edge, which includes bleeding edge OpenCL drivers), were, and have been, the cause of the issue; which is odd as they are what I have always used to get OpenCL support in the past.

To get everything back to fresh I uninstalled the AMD GPU-Pro-20.30 drivers. Rebooted

Reinstalled the Oibaf drivers (running on the assumption that there may have been a remnant in there) Rebooted, then uninstalled the Oibaf drivers. Rebooted.

Now running on the standard Ubuntu 20.04LTS drivers I then installed the OpenCL components from the AMD GPU Pro drivers from above with:

sudo ./amdgpu-pro-install --opencl=legacy,pal --headless

then rebooted

Boinc now loads OpenCL 2.0 as well as OpenCL 1.0 (Which is not in its settings, so it ignores that, but thats ok as most Boinc projects that I run use OpenCL 2 anyway)

Once again thx for your help :)

Yea, besides the 'headless' directive thats how the drivers were installed.

Hey Gang,

Its been a while since ive tried to run the GPU / OpenCL side of crunching, so with AMD releasing its latest drivers for Ubuntus latest long term support 20.04.1 I thought I would try again.

Ive had BOINC happily crunching cpu tasks.

Ive installed the latest AMD Pro drivers with the Vega+ OpenCL drivers

However it seems that BOINC is trying to detect the Radeon 5700XT but the system is denying the request.

Note: The boinc user is part of the video group and boinc is the latest version (7.16.6 x64) from the Ubuntu Repos.

So any ideas?

Thx in advance
