I'm RTFM here. They say to download the tar archive, but the link provided leads to a deb package. Anyway, I was pretty sure my board should support the pro version of amdgpu driver, but I can only see the open version here.

Anyway I downloaded the deb package and installed it. Now I have the amdgpu-install command (NOT pro). But still I can install the Vulkan drivers, which seems not possible from the first link (they should be only in the pro variant). I'm quite confused.

I installed all the stuff using:

amdgpu-install --opencl=rocr --opengl=mesa --vulkan=pro --usecase=graphics,opencl --accept-eula

It completed the installation and I can see stuff under /opt:

$ ls /opt/
rocm  rocm-5.4.3

And here some other outputs:

Still I'm not sure if I have the drivers installed and running. For example I have no vulkaninfo command and Blender does not enable the cycle renderer because it does not find a suitable GPU.

What else should I do in order to enable my graphic card? I'm running Ubuntu 22.10

UPDATE

After seeing the comments, some more clarifications:

  • I tried to install the drivers by myself following the official documentations. Usually, questions that does NOT report this will be downvoted or closed. I showed my effort. I strongly hope this would be appreciated.

  • I'm not asking for an opinion! I'm kindly asking to check what I did and help me to understand if I did it correctly or not

  • if what I did is not the right way to install the drivers, please tell me what procedure I need to follow since I tried to read the manufacturer manual

  • What driver did you install for the graphics card? What version of Ubuntu are you using? – David Mar 31 '23 at 09:22

    So, you've followed a howto by AMD, and now ask for opinions? I hope it is the right way, but amdgpu is also preinstalled. – mikewhatever Mar 31 '23 at 09:29
  • Does this answer your question? Ubuntu 14.04.5/16.04 and newer on AMD graphics – karel Mar 31 '23 at 10:08
  • @David the driver version is reported in the outputs I guess. Ubuntu 22.10 – Mark Mar 31 '23 at 14:07
  • @mikewhatever of course, before posting I try by myself. Otherwise my question will be closed because I did not my homework. And I'm not asking for an "opinion". I kindly asked to inspect what I did and correct me if I did it wrong. – Mark Mar 31 '23 at 14:08
  • @karel sorry, it doesn't fit for me. It's very outdated and I'm confused about all the options the answers suggest. I'm just looking for the right way to install the drivers for the GPU (if I did it wrong) or how to checkout if they are installed correctly, looking at the command I gave. – Mark Mar 31 '23 at 14:10
  • Who told you it was outdated? Probably some stupid old blog. Drivers for AMD graphics processors are preinstalled in Ubuntu by default, so Ubuntu users don't need to guess which graphics drivers to install. – karel Mar 31 '23 at 14:13

    @karel the question you linked talks about Ubuntu 14/16, while I'm trying to install drivers on Ubuntu 22.10. Anyway, if the drivers are pre-installed, why Blender cannot find a GPU to enable cycles? – Mark Mar 31 '23 at 14:15
  • @karel in other words, how to be sure I'm actually using the GPU and not the CPU only? – Mark Mar 31 '23 at 14:16
  • How can I find what video driver is in use on my system? – karel Mar 31 '23 at 14:19
  • @karel did you read my question? I've already reported the output of the command in your link – Mark Mar 31 '23 at 14:24
  • You think we didn't tell you what to do, but we did. Don't keep trying trying to install graphics drivers that you don't need to install. Ubuntu has has been like this for nine years since Ubuntu 14.04 trusty. – karel Mar 31 '23 at 14:28
  • @karel ok, but can you please explain why I can't use my GPU in blender then? – Mark Mar 31 '23 at 14:41
  • Blender 3.0’s Cycles X now runs on AMD GPUs then scroll down to where it says "Which AMD GPUs will Cycles X run on?" – karel Mar 31 '23 at 14:45
  • @karel so my 6800 should be supported... – Mark Mar 31 '23 at 15:11
  • I'm not trying to be snarky but I can actually answer the preceding comment so I will. I'm a macOS user on my other desktop computer and I've installed a lot of open source software in macOS through homebrew. It always installs perfectly and about half the time the software doesn't work after installing it. Lesson learned - don't absolutely trust software from non-official (i.e. non-Ubuntu official) repositories. There's a 50/50 chance that it won't work. – karel Apr 01 '23 at 09:38
  • @karel, ok I removed and purged the official AMD drivers, so I'm running again the default Ubuntu drivers. But the behavior is not changed. – Mark Apr 03 '23 at 06:27

Actually, my procedure was incomplete. To correctly install the drivers I had to invoke the installer with the -y argument after selecting the packages as per the original question.

So, after:

amdgpu-install --opencl=rocr --opengl=mesa --vulkan=pro --usecase=graphics,opencl --accept-eula

I also issued:

amdgpu-install -y

This did the trick and now Blender can see my GPU card. I didn't understand this step from the docs, but I found the hint here.

I did the procedure a couple of times: without the newer drivers from the AMD site, the GPU does not work properly.
