使用 NVIDIA X Server 同时使用笔记本电脑和外接显示器

我设法通过xorg.conf文件设置显示器的显示属性，但我似乎找不到同时使用外部和内置笔记本电脑显示器的方法。这是我的xorg.conf：

通过此设置，只有外接显示器可以工作，但是如果我在两者之间切换线路Screen 0和 ，则只有笔记本电脑显示器可以工作。Screen 1Section "Device"

答案1

类似的问题在这里：只有 HDMI 外接显示器可以工作，笔记本电脑屏幕不能工作。使用 Fedora 32。

经过许多测试选项后，我设法让它与以下 /etc/X11/xorg.conf 一起工作。请注意，这里的关键是允许 NVIDIAGPU 屏幕选项。为此，您需要支持 Prime 渲染卸载的显卡（我的是 Nvidia GeForce RTX 2060）：
