GUI不是从Ubuntu 17.10开始的
我刚把笔记本电脑升级到17.10。 升级很顺利，但启动时，gui将无法启动。 屏幕闪烁，我必须登录终端并停止gdm3。 我已经尝试删除并重新安装NVIDIA驱动程序，但结果相同。 我在syslog中看到了这个：

在遇到类似的问题并找到解决方案之后，我感到愚蠢，但由于我的错误与您的错误类似，直到模块未找到消息，我想我会分享以防它有帮助：
在第三次重新安装nvidia-384软件包之后，我注意到它提到它正在跳过为新的“低延迟”内核构建模块，因为找不到头文件。 按照这些步骤后，我很高兴：
sudo apt purge 'nvidia-*' sudo apt install linux-headers-$(uname -r) sudo apt install nvidia-384
请注意，我确实阻止gdm在尝试任何事情之前使用Wayland，并且据我所知，Wayland目前不会使用nvidia二进制文件，所以我建议通过取消注释来确保它在/etc/gdm3/custom.conf被禁用line #WaylandEnable=false 。
我遇到过同样的问题。 这是我解决它的方式。
- 我以安全模式启动，按Ctrl + F4选择TTY 4（无论如何），使用
sudo apt remove --purge nvidia-*登录并删除所有nvidia驱动程序。 它切换到登录屏幕。 - 我进入了Gnome桌面。 然后我使用
sudo add-apt-repository ppa:graphics-drivers/ppa添加了一个带有最新驱动程序的repo。 - 然后我执行了repo update
sudo apt update。 - 我打开了软件和更新>附加驱动程序，并选择了最新的驱动程序（其中有一些驱动程序，在重新编写此文本时，最新的驱动程序为387.12）。 其他版本失败了。
尝试将nomodeset添加到内核cmdline。 这是我做的最后一件事，现在它起作用了。 这样做之后昨天没有用，我不确定为什么它今天有效，但它现在有效，所以我会接受它。
我的系统也启动但没有GUI。
尝试从内核命令行中删除“quiet splash”但保留“vt.handoff = 7”。
例如
BOOT_IMAGE = / boot / vmlinuz-4.13.0-16-generic root = UUID = xxxxxxxxxxx ro vt.handoff = 7
我有完全相同的问题，并已在ubuntu xorg中打开了一个错误报告（Bug＃1725169）。 也许这是错误的地方，因为它只给了一个回复。 主要问题是lowlatency-kernel的未安装安装。 我可能会影响许多其他人。
