Fingerprintsensor for registration?

[hajuGri49]

Good day friends,

my system runs on a slightly older FUJITSU LIFEBOOK S Series.
Because I had problems with the USB driver for CH340 in Linux Mint 21, I switched to LMDE 5. This solves the problems because my D1 mini and D1 mini pro are recognized here without additional drivers.

I would like to use my fingerprint sensor to log in. The finds on the net were unfortunately not helpful. The suggestions from frame.work with kernel upgrade to 5.16 could not be implemented.

Error message:

Can someone explain to me how I can still use the sensor for registration?

Hello, hajuGri49
How did you determine you need newer kernel and libfprint package to enable the fingerprint sensor on your old lifebook?
All these do not add up. Anyway the unknown to us source you have followed has become apparently obsolete. Backports repo offers 5.18 kernel and Debian testing moved on to a new version of libfrpint and that's the reason why you cannot download the versions you tried to.

It's good to know your own hardware. My bet (I don't have a similar machine) the sensor is connected to the usb-bus. So run lsusb, or usb-devices for a more detailed overview, to obtain device's id.
We must know the model, if proper driver is loaded or you just need to merely configure the device.

But perhaps you even don't need to know anything and you can easily configure your system as described in this how-to: setting up fingerprint authentication on debian bullseye, LMDE5's base system which involves 3 steps:
1. Install the system packages to enable the sensor if they are not already installed:
sudo apt install fprintd libpam-fprintd
2. use the command fprintd-enroll provided by the above fprintd packages to choose a finger to use
3. Turn on the fingerprint authentication with sudo pam-auth-update --enable fprintd

Hy MiZoG
my fingerprint sensor is on
Bus 002 Device 003: ID 08ff:2683 AuthenTec, Inc. Fingerprint Sensor
I have tried the suggested steps.
1. sudo apt install fprintd libpam-fprintd.
2.fprintd-enroll
but after I dragged my finger over it it says: Enroll result: enroll-stage-passed
but it doesn't go any further.
Aborted with contr.C.
Then I typed: sudo pam-auth-update --enable fprintd.
after a restart I land on the authentication with password again.
I could use more help.
Or is my fingerprint sensor not one of the supported ones?
Best regards

Your device is supported

While for Ubuntu / main-branch Mint there is a third-party repo that provides a gui for libfprint,
this doesn't seem to be available on Debian.

Debian wiki specifies that

"First run fprintd-enroll, by default right index finger is read, if you want use other finger, there is -f option, man fprintd...
Finger is read five times. To check, use fprintd-verify."

Thanks for the answer.
Well then I will log in with a password as before.

Hi,
I try this on my Dell inspirion 5593 and get:
Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available

Does this means I can't use my fingerprint sensor? (Didn't use so far, just wish to know if it possible)

Thanks in advance and best regards
