什么会阻止鼠标在xrandr屏幕之间移动？[关闭]

我已经按照本HowTo中概述的步骤进行了操作。

登录Gnome之后，我可以来回移动鼠标，但是一旦加载任务栏，鼠标就会进入屏幕监禁状态（不能在屏幕之间移动）。

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

任何帮助，将不胜感激。我已经很接近要开始工作了！

我最好的猜测是，右侧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，如果您确实希望将DisplayLinkScreen用作主屏幕，请对其进行修改，以使坐标与Screen0的分辨率匹配。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。您可以通过删除来完全重置RandR配置~/.config/monitors.xml。

我在这里找到了一个工具，该工具可以自动在分开的屏幕之间包裹鼠标。

当我无法让鼠标在屏幕之间移动时，它对我有用。

您有两种不同的图形设备，一种带有-intel，另一种带有-displayport，并且想要将它们缝合在一起，以便鼠标在它们之间无缝移动。Xinerama是将多个屏幕拼接在一起的功能，因此您需要启用该功能。

但是，-intel的Xinerama模式并没有得到很好的支持（不过应该会变得更好）。也许您会很幸运的，但是据我所知，这并不可行。

但是，如果使用-nvidia专有的二进制驱动程序，则可能可以使其工作。
