This needs the amdgpu server:
xserver-xorg-video-amdgpu
and
firmware-amd-graphics
and a reboot.
The primary log file for this should be /var/log/Xorg.0.log --
look for complaints there. It should explicitly recognize your
video chipset as an AMD Vega system and then produce lots of
output with the amdgpu prefix. If it doesn't, Xorg isn't firing
up the right driver and you may need to specify it.
