Hey Eric,

i've tried your advice. Had to install dnf first, is not part of the distribution.
When trying the dnf config-manager i got an error message Kein solcher Befehl: config-manager. Bitte /usr/bin/dnf --help verwenden.
The help file does not even list a config command. Do i need a add-on first?

Edit: The Packet-Manager of Mint contains a lot of Rocm packedges. I tried to install some of them only to see that there are a lot of conflicts and the installations never completed. What would be a good starting point here?

Thank you Keith for your kind words.

The reason why i preferred AMD over NV on win was always that the AMD cards were faster and cheaper. Yeterday i tried it on a win machine

06.07.2023 19:07:40 | | OpenCL: NVIDIA GPU 0: NVIDIA GeForce GTX 1660 SUPER (driver version 531.30, device version OpenCL 3.0 CUDA, 6144MB, 6144MB available, 5027 GFLOPS peak)
06.07.2023 19:07:40 | | OpenCL: AMD/ATI GPU 0: AMD Radeon(TM) RX 6500 XT (driver version 3516.0 (PAL,LC), device version OpenCL 2.0 AMD-APP (3516.0), 4080MB, 4080MB available, 5499 GFLOPS peak)

The AMD wu's are 20% faster than the NV

I've tried Linux 5 years ago, was a mess compared to win. But now the installation of both Mint ans debian are much easier and faster than win installations, much more privacy and most programs for my daily use are available. And dual boot systems are easy to install and use.

Let's see, what the future brings regarding the drivers. Is much better than 5 years ago ang hopefully much worse than in one year.

All the best


PS: If someone finds a solution please post that in the project news! Just a headline and a link to the thread.

Took a look into Milkyway forum. Found intresting post, some of them give an impression how AMD works with Linux:

Vega only supported by ROCm 4.5
ROCm 4.5 only supported on 20.04 with 5.11 kernel or 18.04 with 5.4 kernel.

the AMD linux driver situation is certainly all over the place. thankfully nvidia's driver install is pretty painless on both windows and Linux. sucks that AMD's linux experience isn't similar.

I have recently played the match the drivers kernel to the Linux Mint version so I could get my `old` amd7970 running
it worked , eventualy ,finding out then remembering that "Legacy" commandline switch had to be used so that a working open cl would be installed
What a total pain in the #&%$" it was
Two installs of mint , nuked the first 20.2
went back to mint 19.0 as it had the 4.15.0 kernel the driver needed
Then its make shure the card don't cook while crunching coz the fans are far too slow
the back of that card was instant burnt fingers hot
Read a heap more on the web , try it , it don't work , BUT find , dirty hack the file `pwm1` with 255 and its full fan speed for cool crunching .
Though I have an almost identical system that runs win7 ultimate and amd7970s all that OS / drivers / fan speed control stuff is so easy ..
And yet another system that has Linux Mint but with a nv 1060 in it , install driver / install "coolbits" = get work done .
AMD shure duz need to get its act together

But i mean, if a project has Linux AMD GPU workunits, someone of the developers should be able to post a procedure how to enable these gpu's.

Took a PC with NV Card, installed Mint --> works without problems.
Could someone please explain what's the reason why AMD is so full of troubles? And please use a english, that is also good understandable for people with a different language as first language.

Thank you!

Read the posts at Einstein and Milkyway about getting the newer AMD cards which includes your igpu to install the proper drivers with OpenCL support.

You might try this:


amdgpu-install --opencl=rocr,legacy --vulkan=amdvlk,pro --accept-eula

Followed the might try and the, but unfortunately no success.

Will look into Einstein and Milkiway posts now.

No, not a hardware-problem, works fine with windows:

It's the same machine (dual boot).

Thank you for the response.
To make it clear, it is a Ryzen 5 5600G , which means integrated graphic. Will boot it tomorrow into win and join to NumberFields, lets see how well it works with windows drivers. Hardware or software ?

Hi all,
joined today NumberFields with one of Linux PCs and one of my Win10 PC's. Try to port most PC's from Win to Linux and therefor i tried it with debian and Mint.
The problem seems to be the AMD driver.
process exited with code 1 (0x1, -255)</message>
GPU Summary String = [CAL|AMDRadeonGraphics(renoir,LLVM15.0.7,DRM3.42,5.15.0-76-generic)|1|3072MB||101].
Loading GPU lookup table from file.
GPU was not found in the lookup table. Using default values:
numBlocks = 1024.
threadsPerBlock = 32.
polyBufferSize = 32768.
Error: clBuildProgram() returned CL_BUILD_PROGRAM_FAILURE
Build Log:

Error: Failed to initialize OpenCL.

Fails seconds after start.

Tried to run NumberFields on a win PC with AMD and Nvidia. Runs fine, no problems.

Boinc reports:
Mi 05 Jul 2023 23:08:57 | | OpenCL: AMD/ATI GPU 0: AMD Radeon Graphics (renoir, LLVM 15.0.7, DRM 3.42, 5.15.0-76-ge (driver version 23.1.1, device version OpenCL 1.1 Mesa 23.1.1 (git-fa55e3c026), 3072MB, 3072MB available, 1064 GFLOPS peak)
on the Mint PC.

I've started to use Linux just some months ago, so i'm not very experiencd in setting it up correctly, but i will try to do so if ..
.. someone has a solution for me!
Please help me!

Just for Info: it's the latest available Mint distro.
Edit: i'm using the Flathab version of BOINC
