更新后无法在 Ubuntu 14.04 上自动登录

  • 772

我只是做了一些更新，现在我无法自动登录到我的 Ubuntu 14.04。以前，我可以自动登录，有时我不能。我想，这是由 systemd 引起的。这是我的 auth.log 启动时，

我的电脑是macbook pro 13", mid2012。我还在/etc/lightdm/lightdm.conf中添加autologin-user=myusername 了。当然，我还在系统设置>>用户帐户中设置了aulogin。

有解决这个问题的想法吗？我需要自动登录来加快我的启动时间。

    经过一番尝试，我让它再次工作。我不知道哪种解决方案有效，但我执行了以下操作：在 /etc/lightdm/lightdm.conf 中，我添加：

      pam-autologin-service=lightdm-autologin

    我创建新文件 /etc/lightdm.conf.d/50-myconfig.conf 包含以下内容，如下所述：

    [SeatDefaults]
autologin-user=bagustris

    另一个解决方法是检查 /etc/pam.d/lightdm-autologin。确保没有奇怪或权限问题，并参考找到此“ligthdm-autologin”的登录设置。

    这里和这里列出了另一种解决方法：

    sudo chmod a+r /etc/shadow
sudo chown user:user .Xauthority
