I've never had much luck with these displayport connections. My card is 
3x DP and 1x hdmi.

I am considering "starting fresh" on the weekend. The problem is there's 
so much config blended in with KDE now, it's not a simple "remove the 
.kde" folder to wipe the config any more. :/

I don't recall when I last did a fresh install, probably when I built 
this rig in 2018/19. But, I figure with a fresh slate it should be 
easier to get things like wayland to work - at least to give it a try. 
As I know KDE is going more systemd-like I may even try that... although 
systemd gave hits and fisses last time I tried it.
