ThinkPadT480 slimlock指纹解锁
vim /etc/pam.d/system-local-login
将pam_fprintd.so添加到auth部分的顶部
auth sufficient pam_fprintd.so
重新启动计算机，会提示扫描手指以解锁登录(指纹灯亮)
注
slimlock认证后直接回车，不需要输入密码

Impossible to enroll: GDBus.Error:net.reactivated.Fprint.Error.NoSuchDevice: No devices available
运行fprintd-enroll报错

Install fprintd and libfprint-vfs009x-git AUR, then reboot. You can now
enroll your fingers with fprintd-enroll.
github下载很慢
将repository导入到gitee中，并且注意该项目有子模块,
所有需要手动增加.gitmodules

libfprint/meson.build:1:0: ERROR: Unknown options: "x11-examples"
The x11-examples option seems to have been removed. It looks like it's
been replaced by "gtk-examples". I edited that in PKGBUILD and it
built successfully.
https://aur.archlinux.org/packages/libfprint-vfs009x-git
修改build文件, x11-example改成gtk-example
libfprint-vfs009x-git和fprintd >=1.92+版本冲突
安装低版本 sudo pacman -U

thinkpad t480 指纹id为 06cb:009a, 上述一些工具不支持,
直接使用python-validity即可
