I am writting because I am having problems with a new AMD GPU on my main desktop (It has been working fine with a Nvidia card, but I decided to replace it in order to be able to use newer kernels and free drivers).
The card I did choose is a ATI Radeon RX570 (but lspci reports it as an RX 470/480). I am using as CPU a Ryzen7, so I don't have any integrated GPU to produce video output. I followed all the AMDGPU instructions and made sure everything was set in the kernel (4.14.11-r2), bit after what would be loading KMS I only get a black screen. The computer otherwise works and I am able to access it via ssh. Typing my username/password and startx won't start my monitor and X. I don't normally use any initrd image, but after googling I decided to try it out and that won't do anything. I see that someone had the same problem years ago and it was a firmware problem. However, after installing linux-firmware and setting it into the config file I didn't make any change.
The firmware section I did set in my .config is as it says: (the wiki says that the RX570 is POLARIS10)
