Switching from Nvidia to Radeon, or vice versa, means you need to
switch your video drivers and generally a pain in the butt because of
the need to completely remove or blacklist some/all of the previous
driver files.

For some reason I have it in my head that nouveau will not work with
Radeon, but I could be wrong here.

Here's what I'm currently running (Ubuntu 18.04, a Debian variant) and
driving a 40" 3840x2160 and a 24" 1920x1200 display both @ 60Hz, and I
switched from an Nvidia card when I got the 4K UHD display.
