I recently bought the ASUS TUF Gaming FA506IH with Ryzen 5 4600H and dedicated NVIDIA gtx 1650Ti. I am not much of a gamer so I installed Ubuntu 20.04 and thought of not using Nvidia drivers (because of compatibility issue with newer kernels) until I needed it, and just go with the integrated Radeon graphics. However, I noticed that newer gen Radeon graphics are not supported in 5.4 kernel so I installed mainline 5.8 kernel and after installing the amdgpu drivers, it seems to work fine, but I am getting an error with dkms saying it is not supported in kernel 5.8. I also tried xanmod kernel 5.8, but still the same issue. This is the error message that I get when amdgpu tries to build its package on this kernel.

I get the same error when I try installing amdgpu on kernel 5.8.*-generic.

While searching more about this topic. I came to know that you don't really need to install any proprietary drivers for the newer gen AMD Renoir graphics to work on any kernel >= 5.7, because the support already comes out-of-the-box. So I just uninstalled amdgpu using
amdgpu-uninstall
and everything works fine now.As suggested by @red_trumpet in the comments section, you can also install the driver without dkms with the command
./amdgpu-install --no-dkms
. You can also specify an opencl installation using./amdgpu-install --opencl=pal,legacy --no-dkms
. I've tested this, and have been using this for two months now.NOTE: This does not work with the pro version of the driver.
