I got a t480 recently and I am trying to use the Fingerprint reader on it. I installed fprintd and then ran fprintd-enroll but it hasn't worked as it says it can't find any device.

I'm really new to Linux but would love to get my finger print reader working. I'm on 18.04.



I have gotten fingerprint login working on 18.04 and the sensor which comes with a T480s by using the python-validity project.

The basic install steps are

  1. Remove any existing installs of fprintd
sudo apt remove fprintd
  1. Add the python-validity PPA
sudo add-apt-repository ppa:uunicorn/open-fprintd
sudo apt-get update
  1. Install python-validity and dependencies
sudo apt install open-fprintd fprintd-clients python3-validity
  1. Enrol a fingerprint
fprintd-enroll -f fprintd-enroll -f right-index-finger
  1. Enable fingerprint login
sudo pam-auth-update

I have configured a fingerprint scanner on a Lenovo laptop. I used fprintd in order to get it working. I don't remember exactly what I did, but it is better to try this than nothing:

After you have installed fprintd, try to go in gnome-control-panel (I did it in Ubuntu 18.04, so if you are using a different distro it probably won't work). Scroll to the bottom and go to Details > Users > your user > between "automatic login" and "last login", I have an option that says "Login with fingerprint : Turned on". It might not have been so easy when I did it, but I don't remember what I did to configure it, so I don't have a good solution.

I would also try to reboot and try the enroll command again.

  • Hi, I tried this but when I click on the Fingerprint option (when it shows up) it says it can't find any devices. – VirtualHoriz0n Jun 19 '20 at 21:33
