Support for Synaptics Metallica MIS Fingerprint Sensor on ThinkPad T480s Running EndeavourOS?

General system Newbie

Hello everyone,

I have a ThinkPad T480s equipped with the Synaptics Metallica MIS fingerprint sensor (USB ID: 06cb:009a). I have a few questions:

Has anyone confirmed that this fingerprint sensor works on EndeavourOS?
Is it possible to enroll multiple fingerprints and use it for authentication (e.g., for sudo)?
What steps are required to set up this fingerprint sensor (e.g., installing libfprint, fprintd, configuring PAM, etc.)?

Any advice, documentation, or guides would be greatly appreciated. Thanks in advance!

From the Arch Wiki article regarding compatibility with Lenovo laptops, it seems the T480s requires python-validity to work.

Much more than this, sadly, I don’t know what to tell you. I don’t have this model of laptop to help you out. I imagine that once you get the driver installed, you would have the option to add a fingerprint as an authentication method inside your desktop environment of choice.

i just had the same device here to install Linux on for a colleague, and i was able to use the fingerprint sensor properly on EndeavourOS using python-validity.
For Gnome per example it is running properly for GDM without any extra setup aside from getting your fingerprints in (enroll) before.

Do not use fingerprint-gui seems its not working anymore for most people.

On my T480 it is enough to install python-validity. Then enroll your print.

using Gnome and GDM?

Using plasma and sddm. Fingerprint authentication
is not available for initial login under sddm, but you can use it on the lock screen afterwards.

In order to use either a password or a fingerprint, you can instead add the following to the top of the file:

/etc/pam.d/sddm

auth 			[success=1 new_authtok_reqd=1 default=ignore]  	pam_unix.so try_first_pass likeauth nullok
auth 			sufficient  	pam_fprintd.so
