问题如标题所述。当我使用主板图形进行安全加载时，屏幕在登录期间和之后都正常工作。

整个 xorg 日志文件太大，无法粘贴，但我认为包含相关部分的内容是：

我假设其中一个内部显示端口应该显示为已连接？如能提供任何有关如何修复或进一步诊断的帮助，我们将不胜感激
答案1
首先，我使用的是 Ubuntu 18.04 LTS，使用的是目前最新的驱动程序。我自己的电脑也遇到了类似的问题复杂的设置 - 我有一台配备 GTX 1060 的 HP 笔记本电脑，我通过 mini PCIe 将其连接到 PCIe 1x 小玩意。 笔记本电脑本身是横向的，而且我的笔记本电脑的驱动程序使得每当我将笔记本电脑横向翻转时屏幕都会旋转（这在一些但不是很多）。
本质上，我的设置可以归结为：集成 LVDS 面板上的英特尔集成显卡 Nvidia GTX 1060 通过 DVI 输出到外部显示器。
对于遇到此问题的其他用户，请仅在遇到类似问题时继续。我不知道这是否适合您，或者这对配备 AMD GPU 的笔记本电脑来说是否是一个问题。
对我来说不起作用的是：
Nvidia 有一个针对其代码的启动脚本，如下所示：
sh -c '/usr/bin/nvidia-settings --load-config-only'
我尝试用它完成以下大部分操作 - 这就是该代码的来源。
使用 crontab 将 nVidia 的启动脚本添加到启动顺序，以及自定义 xrandr 脚本来修复显示器
crontab -e，然后添加
@reboot sh -c '/usr/bin/nvidia-settings --load-config-only'
編輯.xinitrc
startx
sh -c '/usr/bin/nvidia-settings --load-config-only'
也不起作用。
我还尝试修改了我能找到的所有 rc 文件，然后没有任何其中大部分都起作用了。
按照以下说明将 monitors.xml 复制到 GDM3 的配置中这个 stackOverflow 答案
这部分有效——我的问题部分在于我的笔记本电脑的显示屏还在我登录后才显示出来-盲目地- 我们尝试了多次才弄清楚。
首先，转到设置并验证所有内容是否已按您想要的方式设置。 如果你的设置与我的类似，monitors.xml 文件将只包含一其中的监控配置
sudo cp ~/.config/monitors.xml /var/lib/gdm3/.config
如果您甚至看不到登录屏幕，这将有所帮助。
什么充分工作：
不使用 Wayland 作为登录屏幕，另一个 StackOverflow 答案
首先，你需要执行以下操作：
sudo nano /etc/gdm3/custom.conf
找到这一行（对我来说，它就在下面[daemon]）：
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false
并删除注释，使其看起来像这样：
# Uncomment the line below to force the login screen to use Xorg
WaylandEnable=false
此时，您应该能够保存更改并重新启动。
仅适用于旋转显示屏的用户：
因为我的笔记本电脑是横向的，所以我还必须：按照上述步骤将 monitors.xml 复制到 GDM 的配置中 - 这样可以修复登录屏幕的方向，并且我放入了一个自定义xrandr脚本gnome-session-properties（也称为“启动应用程序”，它是一个 GUI）：
xrandr --output LVDS-1-1 --rotate left
使我的设置完全正常工作。
为什么这有用吗？
说实话我不知道，但我推测这与 nVidia 尚未添加完整的 Wayland 支持或类似原因有关。
