[RESPONDED] FW16 Fingerprint Reader Can Only Register 1 Finger?

Framework Laptop 16 Linux
1

I have a Framework 16 that dual boots Windows and Zorin OS 17 Core. I’m trying to get the fingerprint reader set up, I can register one finger without issue, but when I try to register a second fingerprint on the last scan I get the error “Fingerprint device disconnected” After that the system can’t access the scanner anymore, I just get another error “Failed to claim fingerprint device Goodix MOC Fingerprint Sensor: the device is already claimed by another process.” At this point the only way I can get the fingerprint scanner to work again is to reboot the laptop.

FWIW I do have 2 fingerprints registered on my Windows drive.

Hi @Casey_Reynolds ,

can you check your enrolled fingerprints?

fprintd-list $(whoami)

I’ve had the same problem for some time now. I updated the firmware and did all the things mentioned for ubuntu 22 (since zorin 17 is based on that) but nothing. It will only enroll 1 finger and then disconnect the sensor on the 2nd attempt. I even wiped all the fingerprints with the appimage and tried again. It let me add 1 finger and then blocked the 2nd.

I get the same thing on FW13 pop_os 22.04

Running fprintd-list $(whoami) returns only one entry

Is there a fix, or workaround for this?

I never found one. I just gave up and settled for 1.

I just got my FW13 and am using Pop OS 22.04 on it, with the exact same issue (first fingerprint enrolls, then all others fail with a disconnect error).

I traced the problem to an outdated libfprint; Pop OS 22.04 and Zorin OS 17 are both based on Ubuntu 22.04 and they both are probably using libfprint 1.94.3. I backported libfprint 1.94.8+tod1 from Ubuntu 24.10, then installed that over the supplied release and it fixed the problem; I can now enroll more than 1 print!

If you don’t know how to build Debian packages and you really want a fully functional fingerprint sensor, it might be a good idea to just consider a different distro.
