I have a new Thinkpad X1 Carbon 6th generation. I can see the fingerprint reader right next to the trackpad, and the specs say that it has one, but I don't see it showing up in the output of lspci or lsusb. Maybe I'm missing it? Maybe it's not supported? Or maybe there's a hardware issue? I'm not sure how to tell.

I observed that "Register user sessions in the systemd control group" was not selected, even though my recollection was that it had been selected before I enabled fingerprint authentication, and I didn't disable it. I unselected fingerprint authentication and selected "Register user sessions in the systemd control group" and rebooted again. GDM started working again.
