How can i enable AMDGPU kernel driver? (Ubuntu 22.04)

Question

I'm using Ubuntu 22.04LTS i followed the instructions from another post: how can I use "amdgpu" instead of "radeon" drivers on 20.04? But after rebooting I'm welcomed by this (see image)

Also i can see this weird line, probably related to the kernel driver:

The output of the command: lspci -k | grep -EA3 'VGA|3D|Display' is

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R4/R5 Graphics] (rev 05)
    DeviceName: Onboard IGD
    Subsystem: Hewlett-Packard Company Mullins [Radeon R4/R5 Graphics]
    Kernel driver in use: Radeon

I'm certain that my APU (AMD A8-6410 APU with Radeon R5 M330) is compatible with AMDGPU because i used it in Ubuntu 20.04LTS and in other distros like PopOS, but for some reason in Ubunut 22.04LTS im having issues with it.

Any assistance will be much appreciated (also sorry if my English is bad, I'm not a native speaker)

Hm, just an educated quess: NVIDIA driver don't work with wayland, maybe the AMD drivers don't either. You should change to a X11 Session. I described here how to do it in a terminal.. — kanehekili, Apr 05 '23 at 23:18
Aye, but the issue is that i can't even get into the login screen, it freezes right before the gui "spawns" and neither i can get into my terminal, but imma try it. — Hunter_115, Apr 06 '23 at 00:28
@David i was on Kernel 5.19 the default one, right now I'm on the 6.2 Kernel, i still have that kernel, didn't remove it as some guides say — Hunter_115, Apr 06 '23 at 08:28
if nvidia will not work on wayland, and I am using per echo $XDG_SESSION_TYPE wayland, then why is Ubuntu giving me an option when I search for an app, eg VLC, right clicking it, launch using discrete graphics? I have manually installed drivers installed (though it does not say what in my software additional drivers field) — pierrely, Apr 09 '23 at 02:00

just to share a workaround for this issue, because after digging up for a bit i realized that the kernel 5.19 has issues with legacy AMD hardware (2015 and early) that tried to use the AMDGPU kernel driver which crashes your system on boot up.

What i did was simply upgrade my kernel to 6.2.9-060209-generic by following the steps shared here: https://askubuntu.com/a/1388117/236992 In my case i used the shell script and it worked:

rodrigoal@rodrigoal-HP-Pavilion-14-Notebook-PC:~$ uname -r
6.2.9-060209-generic

Afterwards i edited my grub file: sudo gedit /etc/default/grub

I added the following after the "quiet splash" radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.dc=1"

It looked like this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.cik_support=0 amdgpu.cik_support=1 amdgpu.dc=1"

For my hardware is was cik because my integrated gpu is a Radeon R5 M330.

Once that was done, i saved the edit and executed the following command:

sudo update-grub2

Once it finishes you reboot your PC/laptop.

Now the output of the command lspci -k | grep -EA3 'VGA|3D|Display' should be like mine:

00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Mullins [Radeon R4/R5 Graphics] (rev 05)
    DeviceName: Onboard IGD
    Subsystem: Hewlett-Packard Company Mullins [Radeon R4/R5 Graphics]
    Kernel driver in use: amdgpu

Hope this helps anyone else who suffers from the same issue.

This is not a supported kernel and will cause issue with future upgrades. — David, Apr 06 '23 at 07:49
The 5.19 is the kernel series there are updates to it all the time. So maybe there is a newer 5.19 then the one you had before. A full kernel number would be 5.19.xx — David, Apr 06 '23 at 08:39
I think this is a valid solution. Thanks for sharing @Hunter_115 — kanehekili, Apr 06 '23 at 09:56
@David The full kernel name was: linux-image-5.19.0-38-generic, it updated from the linux-image-5.19.0-32-generic, both versions had the same issue sadly. — Hunter_115, Apr 06 '23 at 19:46
