well, today i (partially) realized why my basic drivers don’t work: the preinstalled packages amdgpu and amdgpu-dkms seem to not work due to amdgpu-dkms being unconfigured. tried configuring it and got the same error. around about there my system stopped using even the iGPU and i had to uninstall some other drivers (thanks @lena@gregtech.eu )
Kbuntu 22.04 w/ radeon R9 M360
Have you enabled Southern Islands support as a kernel parameter? Your generation of GPU was originally supported on
radeon
, so you need to explicitly enable SI (Southern Islands) support to useamdgpu
