Ebuilds

open-fprintd & python-validity

These packages add support for Validity fingerprint sensors, as found on ThinkPad T460 & T470 series laptops.

Original ebuilds written by Mattéo Rossillol‑‑Laruelle (@beatussum), enhanced by Matteo Salonia (@saloniamatteo).

The exact hardware IDs supported currently by this project are the following:

138a:0090
138a:0097
06cb:009a

For more info, refer to open-fprintd & python-validity

In order to use it, follow these steps:

• Emerge the required packages (run as root):

  emerge fprintd open-fprintd python-validity

• Download the required firmware (run as root):

  validity-sensors-firmware

• Start the services (run as root):

  rc-service open-fprintd start
  rc-service python-validity start

• Enroll a fingerprint:

  fprintd-enroll <your-user> -f <your-finger>

  Example:

  fprintd-enroll matteo -f right-index-finger

If you have any issues with the fingerprint reader, try to reset it with the following command (run as root):

python /usr/share/python-validity/playground/factory-reset.py

Wait a minute or so before trying the device again.

If you want to login using your fingerprint, modify /etc/pam.d/login and prepend the following line:

auth	sufficient	pam_fprintd.so

Users that do not have a configured fingerprint will login normally.
