Ubuntu 重启后绕过登录屏幕

我已经使用 ubuntu 16.04 两周了。当我登录 ubuntu 时，它会绕过登录屏幕直接进入桌面，经过 5-10 秒的冻结/延迟后进入登录屏幕并要求输入密码才能继续，这应该在第一次尝试时发生。我尝试重新启动 lig​​htdm 并进入硬终端，但 tty7 屏幕仍然没有响应。这是 /etc/lightdm/lightdm.conf 文件的内容

autologin-guest=false
autologin-user=ravish
autologin-user-timeout=0

尚未找到任何解决方案。如能提供任何帮助，我们将不胜感激！

没有 Xorg.log，但我在 apport.log 中发现了这些错误

从 /etc/lightdm/lightdm.conf 中删除以“autologin”开头的行。这应该可以解决您的第一个问题：它不会再自动登录您。

仅供参考 - 我的 16.04 中的 lightdm.conf 如下所示：

[SeatDefaults]
greeter-show-manual-login = true
greeter-hide-users = false
allow-guest = false

下一步，查看各种日志文件，寻找再次退出的原因：

  • /var/log/lightdm/*.log
  • /var/log/Xorg.?.log
