Hi Folks,
Has anyone had success using a fingerprint scanner for Gnome login? I'm currently
on a ThinkPad X230, but did have the fingerprint scanner working on an X60
working under Trisquel about 8 years ago.
I added "(service fprintd-service-type)" to my Guix System services list and
"fprintd" to my packages. I also added myself to the "input" group, which I
suspect might be required to enroll fingerprints as regular user. After a reboot
I can run "fprintd-enrol" and "fprintd-verify" to add fingerprints.
I was initially unable to log in to Gnome at all (no password prompt), getting
the error:
"Sorry, fingerprint authentication didn't work. Please try again."
After another reboot, I did get a password prompt and can login by password, but
that error message flashes rapidly below. The fingerprint scanner also doesn't
light up, so I assume it's not being activated for some reason.
Any suggestions or thoughts on how to troubleshoot this?
Regards,
Ben

I do not use GNOME or fprintd but the manual page says it's a DBus
service that comes with a PAM module.
I am not sure that fprintd-service-type installs the PAM module, so
maybe that happens in GDM. I was further unable to find your error
message starting with "Sorry" in the Gilab repos for libfprint or
fprintd. [1]
I would snoop around in /var/log/messages or nearby files with grep.
Logging is a wonderful thing.
Kind regards
Felix
