双 GPU xorg.conf 忽略一个 GPU 上的 XScreen 并使用 xrandr

双 GPU xorg.conf 忽略一个 GPU 上的 XScreen 并使用 xrandr

双 GPU X11 使用 xorg 来分离工作负载和屏幕。 2 个 GPU 3 个屏幕/监视器。基本上

GPU 0 => XScreen 0.0 => 监视器 0（左）

GPU 1 => XScreen 0.1 => 监视器 1（中心）

GPU 0 => XScreen 0.2 => 监视器 2（右）

当我设置此系统时，系统仅承认 2 个 XScreen（每个 GPU 一个），然后将侧翼屏幕集中在一起，从而破坏了布局。

任何关于为什么会发生这种情况的意见都将受到赞赏。

尝试将屏幕设置添加到每个设备部分：

Section "Device"
    Identifier  "Card0"
    Driver      "amdgpu"
    BusID       "PCI:48:0:0"
    Screen      0
EndSection

Section "Device"
    Identifier  "Card1"
    Driver      "nvidia"
    BusID       "PCI:16:0:0"
    Screen      1
EndSection

Section "Device"
    Identifier  "Card2"
    Driver      "amdgpu"
    BusID       "PCI:48:0:1"
    Screen      2
EndSection

我有类似的设置，这是我能看到的唯一明显的区别。
