什么可能会阻止 xrandr 屏幕之间的鼠标移动？

Question

我已按照此HowTo 中概述的步骤进行操作。

在我登录到 Gnome 后，我可以来回移动鼠标，但是一旦任务栏加载，鼠标就会在其所在的屏幕中被监禁（无法在屏幕之间移动）。

这是我的 xorg.conf：

 Section "ServerLayout"
            Identifier     "Layout0"
            Screen      0  "DisplayLinkScreen" 0 0
            Screen   1  "Screen0" LeftOf "DisplayLinkScreen"
            InputDevice    "Keyboard0" "CoreKeyboard"
            InputDevice    "Mouse0" "CorePointer"
            Option     "Xinerama" "0" #Could not get this to work it has to be disable
EndSection

任何帮助，将不胜感激。我非常接近让这个工作！

我最好的猜测是右屏幕的位置导致了问题。您可以尝试像这样修改 ServerLayout 部分：

Section "ServerLayout"
        Identifier     "Layout0"
        Screen         0 "Screen0" 0 0
        Screen         1 "DisplayLinkScreen" RightOf "Screen0"
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "Mouse0" "CorePointer"
        Option         "Xinerama" "0"
EndSection

或者，如果您确实希望 DisplayLinkScreen 成为主屏幕，请修改它以使坐标与 Screen0 的分辨率相匹配。例如 Screen0 的分辨率为 1900x1200：

Section "ServerLayout"
        Identifier     "Layout0"
        Screen         0  "DisplayLinkScreen" 1900 0
        Screen         1  "Screen0" LeftOf "DisplayLinkScreen"
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "Mouse0" "CorePointer"
        Option         "Xinerama" "0"
EndSection

问题的另一个可能位置可能是在 gnome 启动期间加载的 RandR 配置中。您可以通过删除~/.config/monitors.xml.
