Fingerprint reader on Debian 13?

Help

Hello,

I’m using Debian Trixie and I’ve discovered I have a fingerprint reader which is working after installing fprintd !
$fprintd-enroll is working
The GUI User configuration is working too (I can add a fingerprint)…

I can’t unlock my session with it, either at startup or on the lock screen (after a sleep).

There is no file /etc/pam.d/kde*
If I don’t put any password and then type Enter, nothing happens with my fingerprint.

Any idea ? Thanks !

Hi! I am in the same position. I am using debian 13, enrolled my fingerprint but I am unable to unlock my screen with it. Using KDE.

I’ve tried some things but still no progress, sorry.

The solution is running ”sudo pam-auth-update --enable fprintd“ (without the “) in the terminal app sadly looks like the gui set up process doesnt enable it automatically

It does not! This enables fingerprint using for sudo commands or after sleeping and logging in but not for logging in after startup.

Exactly. It works quite well on Debian 13.

How does it work well if the most important, always occuring first login after startup does not work with fingerprint?

I understand ; my uptime is like 110 days. I only use sleeping mode.
