sddm + pam_kwallet5 + pam_usb = “open_session 调用时未使用 kwallet5_key”

tag-icon • tag-icon pam kwallet sddm
sddm + pam_kwallet5 + pam_usb = “open_session 调用时未使用 kwallet5_key”

设置并运行 pam_usb 后，当我在 SDDM 中输入密码并连接 USB 密钥时，Plasma 启动后，我看到 kwallet 未解锁。插入 USB 密钥时不会发生这种情况后我登录了。当问题出现时，我可以在日志中看到以下消息：

以下是相关的 pam 文件：

如何配置 pam_usb 和 pam_kwallet(5) 以使其共存？

我没有找到比以下更好的东西：

cat /etc/pam.d/common-auth

auth sufficient pam_usb.so
@include common-auth-nousb

cat /etc/pam.d/common-auth-nousb

auth    [success=1 default=ignore]      pam_unix.so nullok_secure try_first_pass
auth    requisite                       pam_deny.so
auth    required                        pam_permit.so

head /etc/pam.d/sddm

#%PAM-1.0

# Block login if they are globally disabled
auth    requisite       pam_nologin.so
auth    required        pam_succeed_if.so user != root quiet_success

# auth    sufficient      pam_succeed_if.so user ingroup nopasswdlogin
@include common-auth-nousb
# gnome_keyring breaks QProcess
-auth   optional        pam_gnome_keyring.so

这虽然pam-auth-update没用，但却达到了目的：现在我可以使用插入的密钥闪存驱动器进行启动，而无需手动解锁 kwallet。
