Hm, ok, I may have not been clear with my problem.

Xorg DID work before. It certainly won't accept radeon driver - it's RX560. I certainly had working Xorg about two weeks ago. Then after a reboot, boom, no more graphics.

So my configuration is right.

Even though I don't need the whole xorg.conf, I need xorg.conf.d directory with a snippet that forces GPU to use to use amdgpu X11 driver - otherwise it tries to use modesetting.
