2013 年 6 月 3 日对系统进行的例行更新似乎导致我的 Ubuntu 12.04 无法启动。我尝试安装二进制 Nvidia 驱动程序，因为这之前曾给我带来过问题，但问题似乎出在别处。
这是来自 /var/log 的 boot.log。该过程实际上挂起了，我被迫重新启动。我猜它在 VMware 东西失败后某个地方挂起了。我不知道为什么它需要在启动期间启动 VMware。

我遇到了类似的问题...我被告知检查位于 /home/your_username 中的名为 .Xauthority 的隐藏文件的权限。
如果权限由 root 拥有，您将无法登录系统，并且会卡在启动会话中。
使用 chown 命令更改权限以成为 Xauthority 的所有者，然后您就应该能够登录。
