我有一台运行 Ubuntu 18.04 LTS 的联想 E570 机器（配备 Nvidia GTX 950M）。一切都运行正常，直到今天早上 Ubuntu 启动卡在Started Gnome Display Manager。有趣的是，如果我进入恢复模式然后恢复正常启动，我的桌面环境就可以访问。
脚步
遇到此错误后，我尝试了几种方法：
- 按照这个答案，我删除了 Nvidia 驱动程序。
- 删除 gdm3（Gnome 桌面管理器）并再次安装
- 安装并尝试了不同的桌面管理器，包括 LightDM、SliM（并逐一将它们设为主要桌面管理器），但这也不起作用（附加日志）。
- 从步骤 3 的日志中发现这是 X.Org X Server 的问题（日志已附上）。删除并再次安装该软件包
xserver-xorg - 从 Ubuntu 软件更新管理器安装 Nvidia 驱动程序
上述选项似乎对我都不起作用。我在这里忽略了什么？
我的 Linux 内核是 4.15.0-109-generic

答案1
所以我终于能够解决这个问题了。我通过在这个报告的错误中实现 Marek Lipka 的答案来解决这个问题：XServer 中的分段错误
完成此步骤后，登录屏幕陷入循环，我使用 SiddharthaRT 在此报告的错误中的答案解决了该问题：Ubuntu 陷入登录循环（这是一个非常简单的步骤）
