录入指纹及解锁

fprintd-enroll

按照下述同时，录入指纹，直到completed

Using device /net/reactivated/Fprint/Device/1
Enrolling right-index-finger finger.
Enroll result: enroll-stage-passed

校验指纹是否正常fprintd-verify

Using device /net/reactivated/Fprint/Device/1
Listing enrolled fingers:
 - #0: WINBIO_ANSI_381_POS_RH_INDEX_FINGER
Verify result: verify-match (done)

查看当前用户指纹 fprintd-list 用户名

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

问题列表

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been replaced by "gtk-examples".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
