Trackpoint和Clickpad：启用按钮并滚动（Lenovo T440s）[关闭]

我刚刚得到了配备有突触式触摸板的联想T440s。默认情况下，触摸板的右下角没有中间按钮，而右按钮则位于触摸板的右下角。我已经习惯了将trackpointer +左/中/右按钮组合在一起，我真的很想念我的新模型。每次按下按钮时，都会产生一些噪音，因为按钮也是触摸板的一部分。

到目前为止，我所做的是：

• 将触摸板的迟滞值提高到很高的值，这实际上会禁用导航
• 启用Clickpad模式，该模式提供中/右键功能
• 在触摸板上按预期定义中/右按钮区域

但是问题是中间按钮没有映射到Trackpointer。在该模型上，它们似乎是两个独立的设备。我想知道如何将中间按钮触发的事件连接到Trackpointer的滚轮仿真按钮。

这是我的xinput属性的输出：Xinput列表：

我到处搜索并检查了很多线程，但找不到合适的解决方案。但是，当我在此型号上使用Windows 8.1并安装Synaptics触摸板驱动程序时，它运行良好。因此，另一个建议是将该驱动程序移植到linux。

任何帮助将不胜感激，谢谢！

如果我确实正确地理解了您，那么Peter Hutterer的这篇文章可能会对您有所帮助。T440跟踪点按钮支持似乎仍在进行中，目前是一种解决方法。

他用ASCII技术说明了他们无法像Windows那样配置触摸板：

+----------------------------+
| LLLLLLLLLL MMMMM RRRRRRRRR |
|                            |
|                            |
|                            |
|                            |
|                            |
|                            |
| LLLLLLLL          RRRRRRRR |
+----------------------------+

并且必须像这样配置触摸板按钮：

+----------------------------+
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
| LLLLLLLLLL MMMMM RRRRRRRRR |
+----------------------------+

声明和当前解决方法：

我正在为正确的配置制定解决方案，但现在您必须对此有所满足。

本地配置最简单的方法是采用以下形式的新InputClass部分：

Section "InputClass"
    Identifier "t440 top buttons"
    MatchDriver "synaptics"
    #                         right btn|middle btn
    Option "SoftButtonAreas" "60% 0 0 0 40% 60% 0 0"
EndSection

把它放进/etc/X11/xorg.conf.d/99-t440-synaptics.conf去，你就很好了。
