Hello,
My laptop has a goodix fingerprint reader, with id 27c6:550a. I have installed fprintd and the AUR packages libfprint-tod-git, libfprint-2-tod1-goodix, and pam-fprint-grosshack. With this setup it was working for a good few months. A few weeks ago, after an update, it suddenly stopped working. In the output of systemctl status fprintd I get
○ fprintd.service - Fingerprint Authentication Daemon
Loaded: loaded (/usr/lib/systemd/system/fprintd.service; static)
Active: inactive (dead)
Docs: man:fprintd(1)

Since the update was a few weeks ago, I don’t remember if any of the aforementioned fingerprint-related packages were part of the update, but looking through the update history for all of them it doesn’t seem like any of them were. I’ve tried reinstalling all of the fingerprint packages, removing the grosshack package, using the LTS kernel, and even creating a new EOS VM with the device passed through and trying all this. Still no success. Anyone have any ideas?
