But it’s on TTY1, not TTY7 (as I think it should be, no?). Everything in the desktop appears to work. So I typed “systemctl start rvice” and a normal SDDM service launched.

Update, 30min later: I was able to get back in! I had an epiphany: SDDM is “service” based, so may not work right if not launched as a service. So, how can I tell the OS, via command line, to start a SDDM desktop session (on TTY7, presumably)?

I can log in on TTY1 through TTY6, on any of 3 accounts, and do anything that can be done via terminal, but ctrl-alt-F7 does gives just a black screen. Nope! Instead, I now have no desktop at all, just terminals. So today I had the “bright” idea of simply deleting Mate’s display manager, thinking that would force the OS to revert to using SDDM. The desktop was defaulting to Mate, and had to be manually changed to Plasma on every login.The login screen was still using Mate’s display manager, not SDDM.I’m running a Manjaro Linux installation, and a couple days ago I switched my desktop from Mate to Plasma. Yikes, I seem to have screwed things up pretty badly.
