Hi
Create 20-amdgpu.conf and 50-radeon.conf files containing;

cat /etc/X11/xorg.conf.d/20-amdgpu.conf;

Section "Device"
   Identifier "AMD Graphics Core Next GPU"
   Driver "amdgpu"
   Option "DRI" "3"
   Option "TearFree" "true"
EndSection

cat /etc/modprobe.d/50-radeon.conf;
blacklist radeon

Rebuild initrd;

mkinitrd

If it doesn't work you may need the later xf86-video-amdgpu as well.

What is the engineering name of your card (lspci output)? If it's GCN
1.0 series, may need to wait until 4.10 kernel...
