Yes, I have been following step 4 this whole time. I’ve been only operating from a terminal pointing to that directory.

"For now: it’s also a possibility to avoid the problematic package like:
sudo apt install libdrm-amdgpu-amdgpu1"

How? That is the solution you provided for uninstalling the drivers. Without that I was not able to correctly uninstall it. As of this moment I’m not even sure I actually uninstalled it since the new error is confusing to me.

Okay, first things first:
Your uninstall problem.
requires the following steps:
./amdgpu-pro-install --uninstall
./amdgpu-install --uninstall
Just do both.
This should do the trick, at least it always worked in my tests. No matter which combination I tried.
The drivers were uninstalled properly.
If you want, let me know if it works.

AMD changed their drivers!
I found the problem on recent installation attempts.
AMD changed its drivers.
Pal and Legacy headers have been replaced in favor of ROCm and ROCr.

This change also requires the installation of dkms packages and a kernel rebuild,
which is incompatible with Pop!OS.

I’m not entirely sure if the combination of operating system and driver is causing the problem.
Pop! OS 20.10 + Radeon ™ software for Linux® drivers for Ubuntu 20.04.1
Or whether it’s just the change of headers.

From what it looks like, if your kernel is too new, you won’t be able to build DKMS. I’ve been trying to figure out how but had no luck so far. I’m on Kubuntu 20.10 with kernel 5.8.0-29.

When I try to build I get errors mentioning “mmap_sem”. According to this post, anything newer than 5.7 (or maybe that has some patches from 5.7 applied to older kernels) there were changes that won’t allow building DKMS to complete.

Tried the “renamed mmap_sem to mmap_lock” option on the source files and was able to get past the “mmap_sem” errors… and introduced a bunch of new errors. No idea how to fix them.

So until AMD releases a new amdgpu-pro build that works with newer kernels, no OpenCL for me. Or I can reinstall using Kubuntu 20.04 LTS.

You got the --no-dkms option to work? Every time I try, it still tries to build the dkms.

I just ran “./amdgpu-install --opencl=legacy,rocr --no-dkms --headless” and after some other stuff gets done I get this:

Consult /var/lib/dkms/amdgpu/ for more information.
dpkg: error processing package amdgpu-dkms (–configure):

This is going to sound silly, and I’m amazed that it worked myself, but I was running into the same issue and got around it by simply removing the check for --no-dkms in the installer script.

Open up your ./amdgpu-pro-install script and look for the check_options function. Change it to something like this:

    function check_options() {
    #       if [[ "${OPTIONS[*]}" =~ "no-dkms" ]] && \
    #               [[ "${OPTIONS[*]}" =~ "pro" ]]; then
    #               echo -e "ERROR: using --no-dkms with a pro install is "`
    #                       `"invalid.\nDid you want to run the following`
    #                       ` instead?\namdgpu-install --no-dkms" | stderr
    #               exit 1
    #       fi
            echo 'Skipping'

You can’t just remove it because it’s being called elsewhere, but apparently it’s just rejecting you based on the fact you’re running the pro installer. I don’t know DKMS well enough to say if this will cause problems down the line, so run at your own risk. But once I made that modification these instructions worked like a charm - I confirmed with both clinfo and in Blender.

I used the 20.40 driver on PopOS 20.04, not sure how it might behave in other environments.

Edit: I’m on kernel 5.8.0-7630-generic

I know that this thread is not strictly for the case im going to lay out, but I’m writing about it here, in hope there is a possibility that this is GPU driver issue and maybe someone here can help me. This problem is really difficult to diagnose.

For some time I’m struggling with Blender randomly hanging out on me. It’s happenig during multithreaded workloads and the Blender process cannot be killed.

Here is original thread: Blender randomly hangs - what CLI debug options should be enabled for GPU issues?
Here is bugreport:

As of now I’ve uninstalled all AMDGPU-PRO drivers and I’m running some tests to see if this can be ruled out of the equation.

After uninstalling AMDGPU-PRO drivers the issue is gone.

Which driver version were you using?

I’ve been seeing similar behavior recently but no idea what the issue is. I wonder if maybe uninstalling and then reinstalling a different version would help?

EDIT: I started looking into this a bit more and I had the AMD PPA (oibaf-graphics) still enabled from a previous installation attempt. Purging it and keeping my driver version at 20.40 seems to be helping. Here are some instructions on how to remove the PPA if you’re using that and want to see if disabling it helps:

Hello @pzona!
I’m also using 20.40. I’ve reinstalled the drivers with the hack you posted above and everything so far it seems to be OK. Tested Blender versions 2.90, 2.91 and 2.92.
I don’t have PPA’s in sources.

Hmm not sure what the issue was then but glad it’s working!

It looks like my issue was related to the Mesa and Vulkan libraries being upgraded past the AMDGPU driver. If you’re not using the PPA (and are careful when upgrading) you should be okay :slight_smile:

Hey, just asking for the sake of interest, are your Radeon VII pro variants?
If not, the installation without pro might be helpful to solve your problem/s.

./amdgpu-install --no-dkms --opencl=legacy,pal --headless

I’m not sure if you mentioned using the Pro installer or someone else did.

Nevertheless, I would like to point out that, contrary to AMD’s statement, OpenCL can also be installed without the PRO version.

Happy new year.


Following your tutorial now I can’t even open Blender:

AMD Driver Rev: 20.45 is not compatible with system versions >= 20.04.
Blender doesn’t seem to be compatible with it either.
Blender crashes at start, has artifacts in evvee and/or the kernel bulding for cycles is not successful.

As you and your logs say, you are using an RX580. Try the driver version:
Radeon ™ Software for Linux® driver for Ubuntu 18.04.5 HWE. Revision Number
20.40, after a proper uninstall of the current.

Hope this helps, best regards.

Yes, the driver amdgpu-pro-20.40-1147287-ubuntu-18.04 worked for my operating system, although I could not install the pro variant of the driver even with the advice of pzona the standard version works fine with eevee and Luxcore, although I get a message in terminal:

But it seems to have no negative effects on rendering at a glance.
Thanks for the advice.

Hi, I’m not sure if this is mentioned in the guide. I have seen that some Ubuntu users needed to add the Linux “user” to video and render group when installing pro driver with legacy OpenCL (./amdgpu-pro-install --opencl=legacy --headless).

$LOGNAME is your Linux User name.
So for those who can’t get OpenCL working, just in case follow those steps to add the user to those groups.

Hey, thanks for the comment.

I preferred to omit this information because:

  1. This guide has to cover too many marginal cases anyway and is already very bloated.

  2. In forums are many experiences, that the Linux login can be affected.
    Up to a complete rejection of the login.

However, since this information can be found instantly on a Google search, it shouldn’t be too much of a loss.

No problem. I just wanted to mention this in this thread where different tips related to ATI in Ubuntu and derived Linux distributions are being collected.


On Pop 20.10 trying to run ./amdgpu-install, I’m getting the following

PACKAGES: clinfo-amdgpu-pro opencl-orca-amdgpu-pro-icd clinfo-amdgpu-pro opencl-amdgpu-pro-icd

Any idea why that would be? It’s happening with both Rev 20.20 and 20.40.

Thanks, @Tpal. My Radeons are no-pro, but I’m running them with -pro drivers anyway. After reinstall the issue is gone. I think it was related to some Mesa package.

Shame that Blender does not work with either 20.45, or recent 21.10 AMD drivers.

Hey @Tpal

I wanted to report an evolution on my setup as I have upgraded and can run blender 2.92 successfully with OpenCL for my RX580.

OS: Pop’OS 20.10
Kernel: 5.11.0-7614
amdgpu: v21.10
blender: v2.92
CPU: Intel Core i5-8600k

I tried the version 20.50 and that messed up my system pretty badly due to the kernel 5.11 and me experimenting with the amdgpu installer with DKMS - not fully surprised by the result.
I managed to install v21.10 by using ./amdgpu-install --no-dkms --opencl=legacy,pal

When I messed my install with 20.50, I rebooted and amdgpu was gone with other video driver resulting to the system falling back to a 1024x768 resolution.
After checking /etc/modprobe.d folder. After boot, I just loaded the module using sudo modprobe amdgpu and it worked. I also disabled the blacklist that I guess, came from my destructive testing with v20.50.

With regards to Blender v2.92, I tried the flatpak version but there is no amdgpu version integrated into flatpak so the available v2.92 on flatpak does not have amdgpu support.
From the packages, only v2.83.5 is available. I decided to compile blender which worked successfully for me by following this guide:
Make sure to pull the right branch as blender 3.0 is now (as the time of this post) the master branch and very much in alpha version.

I just followed the documentation and can summarize it here:
sudo apt-get update
sudo apt-get install build-essential git subversion cmake libx11-dev libxxf86vm-dev libxcursor-dev libxi-dev libxrandr-dev libxinerama-dev libglew-dev

Then for version 2.92:

mkdir ~/blender-git
cd ~/blender-git
git clone -b v2.92.0

Download libraries - a must (I have tried building them but it is a waste of time):
mkdir ~/blender-git/lib
cd ~/blender-git/lib
svn checkout

And finally:
cd ~/blender-git/blender
make update

I have now the ability to also test future builds which I had not really considered before.
I can launch v2.92 with OpenCL support on my RX580
