在 X11 上，我试图让内部和外部显示器同时工作。nvidia-xconfig生成这个xorg.conf文件：

问题是它只能在外部显示器上工作（当然，任何外部显示器）。现在我正在尝试让内部监视器正常工作。当我重新启动sddm、xrandr或任何其他程序时，尽管仍连接着 HDMI 电缆，但无法看到任何其他显示器/输出设备。请注意，它不会被设置为“已连接”或“已断开连接”，xrandr -q仅返回正在运行的监视器。但是，此命令仍然会找到所有监视器：
[lunar@J-Laptop 06:00:31pm /etc/X11]$ ls /sys/class/drm/*/edid | xargs -i{} sh -c "echo {}; parse-edid < {}"

现在给我的是与 非常相似的语法xorg.conf，即使不是完全一样。如何使用它来使内部和外部显示器都工作？没有任何/etc/X11/xorg.conf，只有我的内部显示器正常工作。
答案1
男人xorg.conf(5)：
配置文件可能有多个
Screen部分。对于正在使用的“屏幕”来说，必须至少有一个。Device“屏幕”代表图形设备（部分）和监视器（部分）的绑定Monitor。Screen如果某个节被活动节引用，则ServerLayout该节 被视为“活动”...
因此，您可以尝试添加第二个显示器和屏幕部分，并将第二个屏幕部分添加到该serverlayout部分。使用位置信息字段来定位您的显示器。
Section "Monitor"
Identifier "Monitor1"
Option "DPMS"
EndSection
Section "Screen"
Identifier "Screen1"
Device "Device0"
Monitor "Monitor1"
DefaultDepth 24
SubSection "Display"
Depth 24
EndSubSection
EndSection
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf 'Screen0"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
EndSection
RightOf、 LeftOf、 Above和Below是可用于定位第二个屏幕的四个关键字。
