我刚刚将笔记本电脑升级到 17.10。升级顺利，但启动时，GUI 无法启动。屏幕闪烁，我必须登录终端并停止 gdm3。我尝试删除并重新安装 NVIDIA 驱动程序，但结果相同。我在系统日志中看到以下内容：

答案1
遇到类似的问题并找到解决方案后，我感到自己很愚蠢，但由于我的错误与您的类似，甚至包括未找到模块消息，所以我想分享一下，以防有帮助：
第三次重新安装软件包后nvidia-384，我注意到它提到它跳过了为新的“低延迟”内核构建模块，因为找不到标头。按照以下步骤操作后，我就可以开始了：
sudo apt purge 'nvidia-*'
sudo apt install linux-headers-$(uname -r)
sudo apt install nvidia-384
请注意，在尝试任何操作之前我确实阻止了 gdm 使用 Wayland，而且据我所知，Wayland 目前无法与 nvidia 二进制文件一起使用，因此我建议/etc/gdm3/custom.conf通过取消注释该行来确保它已被禁用#WaylandEnable=false。
答案2
我也遇到了同样的问题。下面是我解决问题的方法。
- 我以安全模式启动，按Ctrl+选择 TTY 4（无论什么） F4，登录并使用 删除所有 nvidia 驱动程序
sudo apt remove --purge nvidia-*。它切换到登录屏幕。 - 我进入了 Gnome 桌面。然后我使用 添加了一个包含最新驱动程序的 repo
sudo add-apt-repository ppa:graphics-drivers/ppa。 - 然后我执行了 repo update
sudo apt update。 - 我打开了“软件和更新”>“其他驱动程序”，然后选择了最新的驱动程序（有好几个，在撰写本文时，最新的是 387.12）。其他版本都失败了。
答案3
尝试将 nomodeset 添加到内核命令行。这是我做的最后一件事，现在它起作用了。昨天这样做之后它不起作用了，我不确定为什么它今天起作用了，但现在它起作用了，所以我会接受它。
答案4
我遇到了完全相同的问题，并且已经在 ubuntu xorg 中提交了一个错误报告（Bug #1725169）。也许这是错误的地方，因为它只给出了一个回复。主要问题是未经请求安装低延迟内核。我可能会影响到许多其他人。
