如何在 Acer S3 Elantech 触摸板上使用两指滚动？

Question

我在 Acer S3 超极本上安装了 Ubuntu 11.10，我正在尝试让触摸板使用两个按钮滚动。当我转到系统设置 -> 鼠标和触摸板时，我在那里看不到任何触摸板首选项，只有基本的鼠标设置。

当我运行 xinput 时，我得到以下信息：

 虚拟核心指针id=2【主指针（3）】
    虚拟核心XTEST指针id=4【从指针（2）】
    PS/2 Elantech Touchpad id=11 [从指针 (2)]

有谁知道如何让触摸板工作？

Answer 1

首先触摸板支持两指滚动吗？如果是这样的话，编辑的结果synclient -l会很好

添加命令 synclient -l 的输出。

    AreaRightEdge           = 0
    AreaTopEdge             = 0
    AreaBottomEdge          = 0

您可以通过使用以下命令向启动应用程序添加新应用程序来更改 synclient 的设置：

xterm -e synclient "EmulateTwoFingerMinZ=10"

这会将 EmulateTwoFingerMinZ 的设置更改为值 10
