Edit: "Updating to the legacy 580xx drivers doesn't show me a desktop anymore", just in case someone else can stumble upon this by searching something similar.

Thanks to @[email protected] and @[email protected] I did try fixing it out of curiosity. I had forgotten to install linux-headers. Hopefully someone who actually has the same problem as me, and needs to fix it, can use the tips given in the comments. On my end, I just had to install linux-headers and one reboot later it worked.

Always check if you have all needed packages and don't just "remember" that you had them installed.

CPU: Ryzen 9 7900X3D

Mainboard: ASUS TUF GAMING X670E-PLUS WIFI

GPU: Sapphire Pulse AMD Radeon™ RX 7900 XTX Gaming OC 24GB

I had to switch from the Ryzen 7 7800X3D because there is a huge shortage where I live, and it got to the point where it was €100 more than the Ryzen 9. I know I will have a slight performance hit if the game uses the non-3D V-Cache, but I prefer that to spending almost €150 more than the MSRP.

Little side question: Will the Wi-Fi and Bluetooth on the motherboard work in Arch? From what I could gather, the drivers for it should be in the latest kernel, but I'm not 100% sure.
