Indeed, about every third login required a text-mode password prompt, not the
graphical one. It was pretty much random which one I'd get, with about only a
33% success rate in getting the graphical one at all. That has been happening
for at least three years, since I started using OpenSUSE Tumbleweed.

By "text mode password", it was still a full-screen text entry, with the prompt
more or less centred on screen. That's not how I had to boot the last two
times, though, to recover from this bug.
