Fingerprint sensor does not work to login/unlock screen

Help

Hello,

I’m on a fresh install of OpenSUSE Tumbleweed with KDE Plasma 6.3.5 on Wayland.
I used KDE’s System Settings → Users → Configure Fingerprint Authentication to set up my fingerprints, but when I try to login or unlock the screen, nothing happens when I touch the fingerprint sensor.

Here’s the relevant lsusb output:

ceiron@inspiron:~> lsusb | grep Goodix
Bus 003 Device 002: ID 27c6:639c Shenzhen Goodix Technology Co.,Ltd. Goodix USB2.0 MISC

Any additional configuration steps I need to take to get this working?
Thanks!

Hey, I just run into your post while debugging the same issue. Most of the guides online aren’t accurate anymore, because of the changed /etc/pam.d layout OpenSUSE now has. However, I found the following on the “Using Fingerprint Authentication” manual by OpenSUSE themselves:

sudo pam-config --update --fprintd

After running that command, fingerprint authentication is now working for me.

I just registered an account here to reply to this comment, so I am now allowed to include a link to the actual documentation, sorry about that.

Thank you @jbouter! Works perfectly for both SDDM and KDE lock screen.

That’s brilliant @ceiron! I’d like to add that there’s currently a bug in the latest KDE (that we have in tumbleweed) that breaks fprintd unlocking after suspend:

So if you encounter any issues with that, it’s not your configuration but a bug that’s pending to be fixed!
