Well, it only took two reinstalls to sort this out. TL;DR is: don't try to manually install from the Nvidia site before trying the Correct Way(TM).
At least I assume that's what I did the second time. The non-free apt install approach worked fine on my final reinstall (the first failed because I tried KDE Plasma like a fool!)
