I have a T460s with 138a:0090 and this doesnt work

services.fprintd.enable = true;
services.fprintd.tod.enable = true;
services.fprintd.tod.driver = pkgs.libfprint-2-tod1-vfs0090;

When I run fprintd-enroll I get this error

fprintd-enroll

Hey I have a T470s with the same nixos config, and I'm getting the same error:

Maybe this might help you: https://github.com/jasper-clarke/t480-fingerprint-nixos

hey, I don't know if your issue is nixOS related or sth OS-independant. I also have a T460s and finally got the fingerprint reader working following the hints in this thread: https://github.com/uunicorn/python-validity/issues/129 (I'm using arch linux.) maybe it helps you, too! note that you have to stick quite close to the steps described there. i. e. validity-sensors-tools as it is "shipped" may not work (I mean issuing eg. validity-sensors-tools -t initializer) – you'd rather take just a certain part of the python script. In other words: I've just reset my fp reader in the bios and got error messages from fprintd-enroll, so I tried to pair (or whatever exactly) it again. while it didn't work with recent validity-sensors-tools it worked the way described in that thread (for the 2nd time). good luck!
