Here's the version of amdgpu I am using on Ubuntu 22.04: $ apt show amdgpu Package: amdgpu Version: 22.20.50200-1438747~22.04 Priority: optional Section: metapackages Maintainer: Advanced Micro Devices (AMD) <slava.grigo...@amd.com> Installed-Size: 9,216 B Depends: amdgpu-dkms, amdgpu-lib (= 22.20.50200-1438747~22.04) Download-Size: 1,684 B APT-Sources: https://repo.radeon.com/amdgpu/22.20/ubuntu jammy/main amd64 Packages Description: Meta package to install amdgpu components. ... The version of amdgpu on Ubuntu 20.04 did not recognize the card. It gave me a lot of trouble until I upgraded to 22.04 with the 5.15 kernel. Maybe you can try Debian Sid? Jeff
