Answer 1

在138A：0097效度传感器，公司依然是被“逆向工程”，而不是通过简单易用且支持安装fingerprint或他人。

以下是 Nikita Mikhailov 的 WIP（正在进行的工作）：

1. sudo apt install git libusb-1.0-0-dev libxv-dev
2. git clone https://github.com/nmikhailov/Validity90.git
3. cd Validity90/libfprint
4. ./configure
5. make
6. make check
7. sudo make install

Answer 2

您可以尝试使用 @uunicorn 的作品（https://github.com/uunicorn/python-validity）。它适用于我的 Ubuntu 20.04.1。

\n

\n
1. $ sudo apt remove fprintd
\n
2. $ sudo add-apt-repository ppa:uunicorn/open-fprintd
\n
3. $ sudo apt-get update
\n
4. $ sudo apt install open-fprintd fprintd-clients python3-validity
\n
5. $ fprintd-enroll
\n

\n

如果最后一个命令提示错误list_devices failed:，请执行

\n

sudo systemctl status python3-validity\n

\n

检查服务的状态并尝试重置设备：（需要关闭占用设备的所有进程，例如 Ubuntu 20.04.1 上的 \xcc\x8dUsers\xcc\x8d 设置/指纹注册）

\n

\n
1. sudo systemctl stop python3-validity
\n
2. sudo validity-sensors-firmware
\n
3. sudo python3 /usr/share/python-validity/playground/factory-reset.py
\n
4. sudo systemctl start python3-validity
\n
5. fprintd-enroll
\n

\n

您应该能够在命令行上注册指纹。\n现在，如果您使用的是 Ubuntu 20，请尝试转到设置，下面Users应该有\nan 选项。Fingerprint LoginAuthentication & Login

\n

（您可能必须首先在以下位置启用指纹验证pam-auth-update：do

\n

\n
1. sudo pam-auth-update
\n
2. 选择该行Fingerprint authentication，按空格键启用
\n
3. 选择Ok以确认更改）
