[SOLVED] Unable to register fingerprints using fprintd

alba4k · 2023-04-18 19:22:25

Just to be clear, fingerprint unlocks were working perfectly until now (registered my fingerprints last august), until I tried to delete them (fprintd-delete alba4k, I wanted to try to get a better scan to avoid the sensor sometimes not recognizing my finger properly).

Now, I can apparently enroll a fingerprint correctly:

fprintd-enroll -f right-index-finger alba4k

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

(Interestingly, while registering to get an output to post here, I got a couple of

Enroll result: enroll-disconnected

which disappeared after using

fprintd-detele

but this shouldn't be relevant)

Now, I can see my fingerprint

fprintd-list alba4k

found 1 devices
Device at /net/reactivated/Fprint/Device/0
Using device /net/reactivated/Fprint/Device/0
Fingerprints for user alba4k on Goodix MOC Fingerprint Sensor (press):
 - #0: right-index-finger

However,

fprintd-verify alba4k

or trying to use the fingerprint anywhere will fail:

Using device /net/reactivated/Fprint/Device/0
Listing enrolled fingers:
 - #0: right-index-finger
Verify started!
Verifying: right-index-finger
Verify result: verify-no-match (done)

...and now my fingerprint is gone in

fprintd-list alba4k

found 1 devices
Device at /net/reactivated/Fprint/Device/0
Using device /net/reactivated/Fprint/Device/0
User alba4k has no fingers enrolled for Goodix MOC Fingerprint Sensor.

Here are some maybe useful outputs

Also, I found this post on reddit of someone having my same issue, but the suggested workaround doesn't seem to work for me. I do think I had it working at a certain moment, though, some days ago while trying on my won. However, the fingerpritns do not appear to get deleted if I add more than one (or at least, now always).

Some random info:

fprintd version: 1.94.2-1 (same issue using fprintd-libfprint2 from the AUR
Using linux-zen 6.2.11

The sensors appears as

27c6:63bc Shenzhen Goodix Technology Co.,Ltd. Goodix USB2.0 MISC

in lsusb, I'm using an XPS 9320

Does anybody have any idea or has had a similar issue? Is there any useful info I could provide?

Thanks a lot in advance

I have the same problem, already tried https://www.reddit.com/r/pop_os/comment … ngerprint/ but didn't help either.
I have the same sensor and the same outputs. I am running on a Dell Inspiron 14 5410 2-in-1.
When adding two Fingerprints they also don't get deleted, but it still doesn't want to recognize my fingerprint.
I am on a fresh install with gnome and only installed fprintd and so far it never worked for me.

Hope someone knows a solution, would be nice to unlock my laptop using the fingerprint sensor.

Nvm got it to work. I just ran this python script https://gitlab.freedesktop.org/libfprin … te_1063158 and enrolled my fingerprint again and that solved it.

No luck...

Had already tried that.
