在双屏设置中切换 xorg.conf 中的显示器

我想设置一个双屏配置，所以两个完全独立的 :0.0 和 :0.1 屏幕彼此无关。以下配置有效，除了屏幕 :0.0 显示在 VGA 输出（奇怪地称为 DP-1）上，但我希望它在 :0.1 上，而 :0.0 应该是 HDMI-1 输出：

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    Screen      1  "Screen1" RightOf "Screen0"
    Option         "Xinerama" "0"
EndSection

Section "Monitor"
    Identifier     "DP-1"
    Option         "DPMS" "true"
EndSection

Section "Monitor"
    Identifier     "HDMI-1"
    Option         "DPMS" "true"
EndSection

Section "Device"
    Identifier     "Device0"
    BusID          "PCI:0:2:0"
    Screen          0
    Driver         "modesetting"
    Option         "Monitor-HDMI-1" "HDMI-1"
EndSection

Section "Device"
    Identifier     "Device1"
    BusID          "PCI:0:2:0"
    Screen          1
    Driver         "modesetting"
    Option         "Monitor-DP-1" "DP-1"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "HDMI-1"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "Device1"
    Monitor        "DP-1"
    DefaultDepth    24
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

无论我如何命名，xorg 都会不断将 VGA 输出分配给 screen :0.0，我可以在 Xorg.0.log 中看到以下几行：

[     5.314] (WW) modeset(0): Option "Monitor-HDMI-1" is not used
[     5.412] (WW) modeset(1): Option "Monitor-DP-1" is not used

我没有发布整个日志，因为它有 902 行长，但如果您需要更多信息，我可以从中剪切和粘贴任何内容。

您可以通过带有 metamodes 选项的 nvidia 驱动程序执行此操作

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "HDMI-1"
    DefaultDepth    24
    Option         "metamodes" "HDMI-1: nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "Device1"
    Monitor        "DP-1"
    DefaultDepth    24
    Option         "metamodes" "DP-1: nvidia-auto-select +0+0"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

您使用的模式设置驱动程序可能有类似的东西。

似乎有一个ZaphodHeads选项可供您尝试。来自：https : //manpages.debian.org/stretch/xserver-xorg-core/modesetting.4.en.html

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "HDMI-1"
    DefaultDepth    24
    Option         "ZaphodHeads" "HDMI-1"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Section "Screen"
    Identifier     "Screen1"
    Device         "Device1"
    Monitor        "DP-1"
    DefaultDepth    24
    Option         "ZaphodHeads" "DP-1"
    SubSection     "Display"
        Depth       24
    EndSubSection
