Fingerprint Reader is detected, but not usable for unlocking

  • I would like to use my fingerprint reader, and I am able to enrol it in the gnome setting, however when it comes to actually using it, I get the failed to match fingerprint error.

  • I don’t know whether the problem could be that I am permanently asked to swipe over the reader, when in windows I used to just press the reader, but not swipe over it. I am able to enrol it in both ways (pressing and swiping) but cannot use it to unlock anything in either way.

  • My fingerprint reader is detected if I run lsusb:
    Bus 001 Device 005: ID 04f3:0c1a Elan Microelectronics Corp. ELAN:Fingerprint
    and seems to be supported according to the libfprint list of supported devices

  • Here is my System Information:

Any ideas on what to do?

Unfortunately, libfprint’s interpretation of “supported” doesn’t mean “tested to be working correctly for both enrolling and verification”, but simply “we can detect it”. ELAN makes a long list of fingerprint devices, and only a handful of them actually works with libfprint, yours might not be in the list. I also have 2 others in the supported list that can only enroll, but verification totally fails. Debugged, the enrolled image is far from what looks like a proper fingerprint image.

You might want to file an issue to ensure they’re aware of your device problem:

Hi @Gandalfos , also worth going through this page :
https://wiki.archlinux.org/title/Fprint
So you would be using the command line, more than the Gnome UI. which will be a bit more precise.
for any issues, it is good practice to post the outputs of :

journalctl -r -u fprintd.service
systemctl status fprintd

Good luck.
