How to make Ubuntu 22.04 work with a Radeon RX 7900 XTX?

I know that for such new hardware would be better to use a rolling release distro or at least the latest 22.10, but I was wondering if with some tinkering it is still possible to get the latest LTS to work.

As far as I know, to get a 7900 XTX to work on linux you need at least these:

Kernel 6.x+
LLVM 15+
Mesa 22.3+
latest linux-firmware for /lib/firmware/amdgpu/ (and rebuild initramfs)

Is it possible and, if yes, what would be the best way to achieve this on Ubuntu 22.04 LTS?

To get an AMD Radeon RX 7900 XT(X) to work with Ubuntu 22.04 LTS, you can follow these steps:

Install the latest OEM kernel available by running the command:
```
sudo apt install linux-oem-22.04c
```

Download and install the latest kernel firmware from here by running these commands:

wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/snapshot/linux-firmware-20230117.tar.gz
tar -xf linux-firmware-20230117.tar.gz
sudo cp linux-firmware-20230117/amdgpu/* /lib/firmware/amdgpu/
sudo update-initramfs -uk 'all'

Install the kisak-mesa PPT by running these commands (this PPA will take care of providing the latest stable mesa and llvm15):
```
sudo add-apt-repository ppa:kisak/kisak-mesa
sudo apt upgrade
```
Ensure there is no modprobe blacklist for amdgpu by running the command:
```
sudo rm /etc/modprobe.d/blacklist-amdgpu.conf
```

If you use Xorg instead of Wayland and have the issue where the mouse cursor is invisible, you can try to create the file /etc/X11/xorg.conf.d/99-modesetting.conf with the following content:

Section "Device"
      Identifier "modesetting"
      Driver "modesetting"
EndSection

This should make the latest LTS work with your hardware.

For every apt install/upgrade operation, dkms tries to rebuild the driver wrapper and fails. This leaves me with a /etc/modeprobe.d/blacklist-amdgpu.conf after every apt operation pretty much.

I'm not experiencing this issue (just tested to ran `apt update && apt upgrade`). Do you have any other PPAs or dynamic kernel modules that may cause this?

If you use the amdgpu primary drivers I believe they have a dkms component to it. 'amdgpu-install --usecase=graphics,....' The performance improvement is quite substantial.

What do you mean by "amdgpu primary drivers"? Do you mean the `amdgpu-pro`, the one that you download from the AMD website? Or are you talking about the open source `amdgpu` from Mesa? I'm using the latter and I never heard about this extra step. Can you please link some documentation about it?

Performance goes up from 6kfps to 13kfps using the AMDGPU stack with glmark2. https://amdgpu-install.readthedocs.io/en/latest/ https://www.amd.com/en/support/linux-drivers

Can you please try to do some benchmarks with GravityMark? This way we can compare easily the performances: https://www.reddit.com/r/linux_gaming/comments/10ldyhn/gravitymark_benchmark_a_gpu/

Mesa and kernel upgrade was sufficient for me to make 7900XT works.

As @MadMan2064 mentioned in the comments, amdgpu-install from https://www.amd.com/en/support/linux-drivers worked for me with a Radeon RX 7900 XT. Even though I'm on Ubuntu 22.10 (kinetic), the 22.04 version worked. I installed the .deb file and ran amdgpu-install without any arguments, and that was sufficient. No need to install a special kernel or add a ppa.

I also had trouble installing Ubuntu 22.04 correctly (I had a black screen with a flashing underscore), but I was able to launch it in recovery mode, where I had access to the terminal. What worked for me was installing Ubuntu 20.04 first and then upgrading to 22.04.

My GPU is an RX 7900XT.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
