Thank you for the references, Felix.
Unfortunately, nothing you sent is applicable because SDDM doesn't even start in the first place. Computer goes unresponsive when it
Which Intel chipset/CPU model do you have? Skylake? Lotsa troubles with that one not just in Debian. Lotsa troubles generally with any Intel latest in recent years, as Interest from Intel itself is waning, while X driver development focus is on integrated generic modesetting. Last "release" of an Intel video driver (2.99.917) was more than two years ago.

tries to start X and then I have to force shut down. I've been able to start - just - by booting into multi-user.target and masking KDE.unit from GRUB - apparently KDE ignores polite requests not to start up so you have to hide it from systemd entirely. I'll probably spend another tedious couple evenings trying to create log information before I have to force-off the system and then another wild goose chase finding the right package to blame only to discover about a week from now that the interaction between two or more unrelated packages is breaking my system - which is why I'm the only one with the problem.
All my Stretch installations bypass SDDM. It isn't even installed. Either I have KDM, or more often, TDM, but in any event, my default runlevel is multi-user.target anyway, so most often I use startx rather than any graphical login manager.
