Go look in your logs.
I have, in /var/log/Xorg.0.log:
[ 15.416] (II) AMDGPU(0): Creating default Display subsection in Screen
section
"Default Screen Section" for depth/fbbpp 24/32
[ 15.416] (II) Applying OutputClass "AMDgpu" options to /dev/dri/card0
[ 15.416] (--) AMDGPU(0): Chipset: "AMD Radeon RX 580 2048SP" (ChipID =
0x6fdf)
and so on.
I suspect your system is not actually loading the AMDGPU driver
into Xorg, and solving that will solve your problem.
