To make the Lenovo Thinkpad t440s fingerprint scanner in Ubuntu (16.04.3) work, install the following:
sudo apt install fprintd libpam-fprintd
After the install – update the following file to set the timer to unlimited, otherwise the fingerprint scanner will time out during login:
sudo vi /etc/pam.d/common-auth
and look for the line that has the pam_fprintd in the name
auth [success=2 default=ignore] pam_fprintd.so max_tries=1 timeout=10
Usually the default is timeout=10 and max_tries=1, I updated mine like below, so it never times out and I have 2 tries
auth [success=2 default=ignore] pam_fprintd.so max_tries=2 timeout=-1
This works on sudo auth and login from lock, haven’t fully tested yet like startup etc. It is a little unstable though, I had it fail on me few times where it wouldn’t recognize the scanner anymore. I will update this post if I find anything.
After you install a new applet in some versions of Ubuntu (gnome) it will not be available in the list until you log-out and login again or if you do not restart your computer. This is bad because you will need to close everything to perform either of these things, however it is safe to kill the gnome-panel process and it will then automatically re-load and all the new applets will be available in the list.
No root/sudo privileges are needed for this command.
