Public bug reported:

I recently helped my brother upgrade his monitor setup and video card
from an ASUS 750Ti and single Dell 3007WFP to the MSI RX 470 and two
additional Dell SE198WFP on each side. (The 30" had its backlight die,
another story for another time, so in the meantime, I've got a Samsung
2253LW in the menatime. I am still using the original dual-link DVI
cable that came with the Dell monitor.) To hook up the side monitors, we
used some HDMI-DVI cables. (I need to check if the cables are single-
link or dual-link.) Installation and orientation setup was successful in
Windows 10, but in Ubuntu, all that happens is it appears on the side
monitors, duplicated, in 1024*768.

Originally, I thought it was the open-source drivers not communicating
with the card properly, so I installed the AMDGPU-PRO drivers off of
ATI's Web site. Unfortunately, not only did it not resolve the incorrect
resolution/incorrect physical orientation issue, but now Unity is not
loading correctly. I am able to right-click on a black desktop and open
applications (such as a browser, which I'm doing right now), but I have
no window decorations, and I am unable to move or resize the window.

Display settings under unity-system-settings only says that "internal
display" is connected (laughable), doesn't say anything about the
Samsung monitor, and provides no option to not mirror the Dell monitors.

Recently, I tried the suggestion at http://askubuntu.com/questions/17381
/unity-doesnt-load-no-launcher-no-dash-appears, and even reverted to the
open-source driver, but that didn't resolve the issue.
