18.04: ThinkPad p50 Fingerprint Scanner not working even when recommended answer tried

  • 772

Installing fprint and fingerprint-gui do not enable the fingerprint scanner on a Lenovo ThinkPad p50 to work with Ubuntu. If there is another linux-based OS that supports this, I would gladly switch to that, but I haven't found any.

The output from lsusb is:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 138a:0090 Validity Sensors, Inc. 
Bus 001 Device 002: ID 04f2:b596 Chicony Electronics Co., Ltd 
Bus 001 Device 004: ID 8087:0a2b Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Valadity Sensors, Inc. is my fingerprint sensor. How do I get it to work in Ubuntu?

    I had the same problem with my Lenovo P50 and Ubuntu 20.04 ... fixed it combining the following steps from here and here:

    sudo apt remove libpam-fprintd
sudo add-apt-repository -u ppa:3v1n0/libfprint-vfs0090
sudo apt install libfprint-2-tod-vfs0090 
sudo apt install libpam-fprintd

    Enroll your index finder using:

    fprintd-enroll -f "right-index-finger" "$USER"

  2. Okay

    So, I went through the steps on the GitHub page (which I didn't know were there in the first place) and It worked fine. I'm sorry for all your troubles.
