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 @[email protected] )
Generally yes, if you use any modern card. Older ones might require to switch to an older driver (before “amdgpu” there was one called “radeon”, by default any distro I know comes with the modern amdgpu). There are also two AMD GPU generations (I think HD7000/Rx 200 and Rx 300) that can be a little bit nasty as the driver change happened around that time, those sometimes need manual intervention.
Anything newer (RX 550 and higher) pretty much always work without any hitch or additional steps required.
