我有一台带有集成指纹识别器的 Lenovo Thinkpad T430。我想让它与我的密码一起使用，而不是替换它。我的意思是，当出现密码提示时，我希望能够立即输入密码，或者使用指纹识别器而无需任何额外的输入。
我设法让读者使用 fprint。我配置了所有的手指，并将相应的行添加到相应的配置文件中，就像现在一样，每当系统需要 root 密码时，它都会先提示我输入我的手指，如果失败 3 次，它就会给我一个密码迅速的。另外，在我的登录屏幕上，除非我先在空密码提示中按 Enter 键，否则我无法使用阅读器。
我想我应该详细介绍我的登录屏幕和发行版。我将 lightdm 与 webkit2-greeter 一起使用，并为该greeter 定制了一个名为 Aether 的主题。操作系统是带有 Cinnamon 桌面的 Linux Mint 20。正如我所说，我无法使用阅读器，直到我在空白字段上按 Enter 键，然后我就可以毫无问题地登录。我宁愿选择使用我的阅读器登录，而无需任何额外的输入。这些是我的配置文件：
/etc/pam.d/common-auth
#
# /etc/pam.d/common-auth - authentication settings common to all services
#
# This file is included from other service-specific PAM config files,
# and should contain a list of the authentication modules that define
# the central authentication scheme for use on the system
# (e.g., /etc/shadow, LDAP, Kerberos, etc.). The default is to use the
# traditional Unix authentication mechanisms.
#
# As of pam 1.0.1-6, this file is managed by pam-auth-update by default.
# To take advantage of this, it is recommended that you configure any
# local modules either before or after the default block, and use
# pam-auth-update to manage selection of other modules. See
# pam-auth-update(8) for details.
# here are the per-package modules (the "Primary" block)
auth sufficient pam_fprintd.so <-- RELEVANT LINE
auth [success=1 default=ignore] pam_unix.so nullok_secure
# here's the fallback if no module succeeds
auth requisite pam_deny.so
# prime the stack with a positive return value if there isn't one already;
# this avoids us returning an error just because nothing sets a success code
# since the modules above will each just jump around
auth required pam_permit.so
# and here are more per-package modules (the "Additional" block)
auth optional pam_ecryptfs.so unwrap
auth optional pam_cap.so
# end of pam-auth-update config

任何有关我如何实现这一目标的想法将不胜感激，谢谢。
