什么可能阻止鼠标在xrandr屏幕之间移动？

10.04mousexrandrdisplaylink

我按照这个教程中的步骤进行操作。

在我登录到Gnome后，我可以将鼠标来回移动，但是一旦任务栏加载完成，鼠标就被限制在当前屏幕上（无法在屏幕之间移动）。

这是我的xorg.conf文件：

 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

任何帮助都将不胜感激。我离让这个工作成功如此之近！
@Tim祝你好运，我的朋友。我还没能让它工作起来。希望驱动之神会眷顾你。 - Tyler

我个人的猜测是右屏幕的位置导致了这些问题。你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，如果你真的希望DisplayLinkScreen成为主屏幕，那么修改它的坐标，使其与Screen0的分辨率匹配。例如，Screen0的分辨率是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在 Gnome 启动时加载的 RandR 配置中。您可以通过删除 ~/.config/monitors.xml 来完全重置 RandR 配置。

我找到了一个工具这里，可以自动将鼠标在分开的屏幕之间切换。
当我在屏幕之间移动鼠标时遇到困难时，它对我很有帮助。
你有两个不同的图形设备，一个带有-intel，一个带有-displayport，并且想要将它们拼接在一起，以便鼠标可以在它们之间无缝移动。Xinerama是用于拼接多个屏幕的工具，所以你需要启用它。
然而，-intel的Xinerama模式并不是很好支持（尽管应该会越来越好）。也许你运气好的话，它能够正常工作，但据我所知，这并不被期望能够实现。
如果你使用-nvidia专有二进制驱动程序，可能可以使其正常工作。
