Ubuntu使用Thinkpad-T14-Gen1指纹识别

使用sudo pam-auth-update空格勾选Fingerprint authentication后回车可以使用指纹进行sudo验证

/usr/libexec/fprintd

若缺少Fingerprint authentication项目无法登陆执行sudo apt install -y fprintd libpam-fprintd后即可出现

二、安装并测试 FPrint 指纹识别软件

打开 Applications(应用程序)> Ubuntu Software Center(Ubuntu 软件中心)，在搜索框搜索 fprint-demo，安装第一项。

完成后，打开 Applications(应用程序)> Accessories(附件)> fprint project demo，检查是否能够找到设备，此时不用进行登记。

若可以，那就请继续；若不行，请删除 fprint-demo，移除 PPA 源，按照这个页面的指示操作，配置 Fingerprint GUI，它包含 non-free 的包，支持更多硬件，但是和 GNOME 整体的集成更差。(经实测我觉得很山寨 …)

打开 System(系统)> Preferences(首选项)> About Me(关于我)，点选“Enable Fingerprint Login…(启用指纹登录…)”并按提示操作即可。
