Hi there!

  1. It appears like the fingerprint sensor has timed out. This probably indicates a hardware / connection issue, which I sadly cannot really help with.

  2. What are you referring to with "did not help"? More details would be appreciated to help track this down.

777Raim commented 1 year ago

@Popax21, thanks for answer!

What are you referring to with "did not help"? More details would be appreciated to help track this down.

Below are my steps:

  1. Standard output fprint-list $USER (I deleted all my enrolls before):

    found 1 devices
Device at /net/reactivated/Fprint/Device/0
Using device /net/reactivated/Fprint/Device/0
User $USER has no fingers enrolled for Synaptics Tudor.

  2. Trying to enroll my point finger: fprintd-enroll $USER right-point-finger:

    Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
Enroll result: enroll-duplicate

    At journalctl had this:

    13 09:12:05 Notenook-PC tudor_host_launcher[148228]: [INF] Identify result -> matches GUID 45e38506... finger 2

    I think it's mean that fprintd find my 'finger' at it's own base, isn't it?

  3. I found several python scripts to delete all fprintd fingerprints:

For each of they, I had this:

Looking for fingerprint devices.

    The same error as at step 2.

I have that error with 3 fingers: In February I first time built and installed synaTudor and enrolled my fingers - all worked. Some days ago I reenrolled my fingers cos sometimes my fingers didn't match. After that I began have this issue. I rebuilt and installed last git version of fprintd-tod and synaTudor but the issue saves.

Sorry for the late response, I'm just now finding time to (quickly) look into this again. I think there might be a bug in libtudor/tudor-host regarding the biometric record clearing code, as can be seen in the log snippet you sent: it seems to receive the clear request, but it looks like it doesn't actually clear any records

I will let you know once I find the underlying issue.

Thanks for answer! I'm looking forward to your reply.

Popax21 commented 1 year ago

Actually, that makes sense considering no prints have been sent to the host yet. Additionally, fprintd already reported that no prints are stored, so I'm not sure where it is pulling all the extra prints from.

Can you set the env var G_MESSAGES_DEBUG=all in the fprintd systemd unit file, restart both the host launcher and fprintd, then set the journalctl log of both a list, clear, and (failed) enroll, in that order?

777Raim commented 1 year ago

Logs are below: journalctl_fprintd_restart.txt journalctl_tudor_restart.txt journalctl_fprintd_fprint-list.txt journalctl_tudor_fprint-list.txt journalctl_fprintd_remove_by_python.txt journalctl_tudor_remove_by_python.txt journalctl_fprintd_fprint-enroll.txt journalctl_tudor_fprint-enroll.txt

After remove enrolls via python script, tudor enrolls didn't removed. After python removed enrolls, fprintd-list has the same output as before: 2 enrolled fingers.

EDITED: I found "non-deletable" enrolls. I saw location of enrolls at logs (/var/lib/fprint) and I had some wrong users for fingers. I deleted all wrong user's enrolls and now can enroll all my fingers!

Hey, thank you very much for this. It is the only solution that has actually worked for me. However, I wanted to ask, does it only work for login? Like can I not set it to authenticate everything else as well, like when I am using chrome and want to authenticate a password, or like when I want to unlock to make changes in settings and etc.
