Comment 13 for bug 1915570

Can you please modify your `/etc/pam.d/gdm-fingerprint` so that it will use:

 auth required pam_fprintd.so debug

And then provide me output from:
 - grep fingerprint /var/log/auth.log

It may be useful also enable debugging for gdm into your /etc/gdm3/daemon.conf (and provide journal)
