该文件不存在。但我不使用KDE。我的桌面改为在Unity上运行。

— 马丁

我尝试过：sudo apt-get purge kwalletmanager sudo apt-get install kwalletmanager。安装了很多文件。之后重启。但是问题仍然存在。

— 马丁

解决方法如下：从锁定屏幕中选择“切换用户”->使用类似的对话框输入密码->解锁屏幕

我通过安装libpam-kwallet4 libpam-kwallet5解决了。

$ sudo apt-cache search kwallet |grep pam
libpam-kwallet4 - KWallet (KDE 4) integration with PAM
libpam-kwallet5 - KWallet (Kf5) integration with PAM
$ sudo apt-get install libpam-kwallet4 libpam-kwallet5
$ sudo service lightdm restart

您的日志表明存在问题/lib/security/pam_kwallet.so。您能否确定该文件是否仍然存在，可能必须重新加载kwallet：

sudo apt-get purge kwalletmanager
sudo apt-get install kwalletmanager

sudo apt-get install --reinstall kwalletmanager足以重新安装丢失的文件，并且不会删除的配置文件purge。

重建pam身份验证设置。转到另一个TTY CTRL-ALT-F1，然后运行：

sudo pam-auth-update
# Make no changes and select "Ok" to update the config
sudo service lightdm restart
