After successfully enabling Fingerprint Login on my user and enrolling my thumb, I lock the screen and try to unlock it with my thumb but nothing happens. Rebooting the system didn't help. Looking at the logs I found this line in /var/log/auth.log:

gdm-fingerprint]: gkr-pam: no password is available for user

Although I have a password set on my user.

My laptop is Asus UX430UNR, and the fingerprint reader is:

04f3:0903 Elan Microelectronics Corp. ELAN:Fingerprint

What am I missing?

Just resolved a problem that looked the same. The actual problem was that I didn't know how to swipe.

Check if you can swipe with $fprintd-enroll and then $fprintd-verify (in the terminal emulator). If you can't pass, see here. TL;DR one should swipe carefully from the finger base to the tip, both in the configuration and the verification.

  • Apparently I was swiping a smaller than necessary portion of my finger, during both enrollment and verification. Thanks.
