Working with 06cb:009a Synaptics, Inc.

Hi there, I’m trying to make work this fp.

I saw that there are blobs_90.py are blobs_97.py . Are these binary blobs taken from the firmware extracted from the windows installer?

How can I know which one is init_hardcoded , init_hardcoded_clean_slate, etc ?

Thanks for your reply

Hello @uunicorn, I succeeded to authenticate through pam_fprintd.so with your two repos, open-fprintd and python-validity. My hardware is 06cb:009a (thinkpad x1 carbon gen6) and os is ubuntu 20.04. My configuration procedure is below. Sorry for my bad english.

[Histories] 07/08/2020 : first version. 07/09/2020 : @uunicorn has released “open-fprintd” and “fprintd-clients”, so I have updated the following instructions.

1. open-fprintd and fprintd-clients installation:

    $ sudo apt remove fprintd
    $ sudo add-apt-repository ppa:uunicorn/open-fprintd

   #  [note]
   # If you're ubuntu 20.04 user,  please edit "focal" to "bionic" in /etc/apt/sources.list.d/uunicorn-ubuntu-open-fprintd-focal.list
   # because this repository does not have focal packages.
   ======
   deb http://ppa.launchpad.net/uunicorn/open-fprintd/ubuntu bionic main
   ======

    $ sudo apt-get update
    $ sudo apt install open-fprintd fprintd-clients

1. register open-fprintd to systemctl.

    # create /etc/systemd/system/open-fprintd.service, and contents is below.
    =======
    [Unit]
    Description=open-fprintd daemon
    
    [Service]
    Type=simple
    ExecStart=/usr/lib/open-fprintd/open-fprintd
    Restart=always
    
    [Install]
    WantedBy=multi-user.target
    =======

    # start open-fprintd daemon.
    $ sudo systemctl enable open-fprintd
    $ sudo systemctl start open-fprintd

1. pull python-validity(arbitrary directory, my case was /opt.):

    $ git pull https://github.com/uunicorn/python-validity
    
    # install relevant python packages:
    $ sudo apt install libgmp3-dev
    $ sudo pip3 install pyusb
    $ sudo pip3 install fastecdsa

    # download firmware, and factory-reset and pairing.
    # (refer to python-validity's readme)
    $ cd /opt/python-validity
    $ sudo python3 factory-reset.py
    $ sudo python3 pair.py

    # create script for systemctl daemon.
    $ vim /opt/python-validity/start_dbus.sh
    
    # contents in /opt/python-validity/start_dbus.sh is below:
    ======
    #!/bin/bash
    
    cd /opt/python-validity
    export PYTHONPATH=$PYTHONPATH:/opt/python-validity
    python3 dbus-service.py
    ======

    $ chmod 755 /opt/python-validity/start_dbus.sh

    # create DBus service file for dbus-service.py.
    sudo vim /usr/share/dbus-1/system-services/io.github.uunicorn.Fprint.service
    
    # contents in /usr/share/dbus-1/system-services/io.github.uunicorn.Fprint.service is below:
    ======
    [D-BUS Service]
    Name=io.github.uunicorn.Fprint
    Exec=/opt/python-validity/start_dbus.sh
    User=root
    ======

    # create DBus conf file for dbus-service.py.
    sudo vim /usr/share/dbus-1/system.d/io.github.uunicorn.Fprint.conf
    
    # contents in /usr/share/dbus-1/system.d/io.github.uunicorn.Fprint.conf is below:

    =======

    # start python-validity daemon.
    $ sudo systemctl enable python-validity
    $ sudo systemctl start python-validity

1. execute fprintd-enroll command.

    $ fprintd-enroll

1. pam configuration to enable fingerprint authentication :

    $ sudo pam-auth-update

    # And, modify /etc/pam.d/common-auth
    auth    sufficient      pam_fprintd.so max_tries=1 timeout=10 # debug
    auth    [success=2 default=ignore]      pam_unix.so nullok_secure try_first_pass

That’s all ! You’ll be able to login by fingerprint reader.

Very very appreciate to your great work! Thank you!
