Fingerprint Reader Lenovo Thinkpad L13 - Synaptics Driver

I read some of the questions here about the fingerprint reader support. Here I am asking spcecifically for the Lenovo Thinkpad L13.

I am using Ubuntu 19.10 but I think it would be the same for other versions.

lsusb shows ID 06cb:00be Synaptics Inc.

I installed libpam-fprintd fprint-demo and libfprint0

fprint-demo says No devices found.

Is there any driver for this Synaptic device available?

Or how can I use the fingerprint sensor with Ubuntu

For now, it's really tricky.

19.10 uses outdated fwmgr and fprintd. You'll need at least fwmgr-1.3.5 and fprintd-1.90. They are available in next Ubuntu release - focus which is on early stage of development.

You can get up-to-date version of fwupd package from snap, but you should build fprintd-1.90 packages from source.

Also, fingerprint reader firmware should be updated, but this is tricky as well, because firmware you need is marked as testing and current version of fwupd fails to download it.

All in all, I spent all evenings this week tinkering and finally managed to get it working. I would suggest to wait for Ubuntu focus where fingerprint will be working out of the box.
