禁用“假”X11 会话中的额外监视器

我的系统中有 3 个 NVIDIA GPU。一个用于显示，两个用于计算。我想调整两个计算 GPU 的风扇曲线，据我所知，所有当前方法都需要运行 X 服务器才能使风扇控制发挥作用（有人说他们可以打开 X，调整风扇速度并将其关闭但那些对我来说永远不起作用）。

没关系，我打开了 X，但没有使用以下命令将显示器连接到它们sudo nvidia-xconfig -a --cool-bits=28 --allow-empty-initial-configuration并且它可以工作。问题是它还引入了新的“显示器”或“X Screen”，它们以某种方式成为我工作空间的一部分。这是真的很烦人，因为我的鼠标经常会超出边界进入“假屏幕”。

我考虑使用鼠标捕获脚本 - 一个连续监视鼠标并将鼠标发送回有效工作空间的程序。不过我真的不想浪费我的 CPU 时间。

我检查了所有设置，nvidia-settings但找不到禁用它们的方法。

这是我的Xorg.conf：

# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig:  version 440.95.01

如何禁用额外的屏幕？

答案1

绝对欢迎更好的答案。我很长时间以来一直在尝试解决这个问题，这是我拥有的最好的技巧。当我随机尝试 nvidia-setting 中的每一个设置时，我得到了洞察。一个警告说“绝对位置只能为屏幕 0 设置，否则某些屏幕可能无法访问”。不能达到！这正是我想要的！

无论如何，我将额外的屏幕“移动”到远处的绝对位置，一切正常，只有以下内容需要更改。

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    Screen      1  "Screen1" Absolute 1000 0
    Screen      2  "Screen2" RightOf "Screen1"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection
