--- Comment #6 from Joseph Olstad <joseph at 7pro.ca> ---
Originally trying to get dual screen to work on Debian Stretch kernel 4.9.x

Led me to kernel update , Debian Stretch with latest 4.13.x kernel
I didn't log the issue that 4.9.x had but maybe similar to 4.13.x
:see following:
dmesg | grep amdgpu
