DDX means Device Dependent X.

I wasn't aware that amdgpu would ever work automatically with sea islands.
Normally it needs radeon.si_support=0 and amdgpu.si_support=1 to use it.

Try purging xserver-xorg-video-amdgpu and xserver-xorg-video-ati, then restarting
X. That should automatically result in using the modesetting X driver. It does for
my sea islands. If it's OK, either keep it that way, or try reinstalling only
xserver-xorg-video-amdgpu.
