Trackpoint和Clickpad：启用按钮和滚动（Lenovo T440s）
我刚买了一台装有synaptics触控板的联想T440s。 默认情况下，没有中间按钮，右按钮位于触摸板的右下角。 我已经习惯了trackpointer +左/中/右按钮的组合，我真的很想念我的新模型。 每次按下按钮都会产生一些噪音，因为按钮也是触控板的一部分。
到目前为止我做的是：
- 将触摸板的滞后增加到非常高的值，这实际上禁用了导航
- 启用Clickpad模式，提供中/右按钮function
- 在触摸板上按预期定义中/右按钮区域
但问题是中间按钮没有映射到trackpointer。 它们似乎是这个型号上的两个独立设备。 我想知道如何将中间按钮触发的事件连接到trackpointer的车轮仿真按钮。
这是我的xinput属性的输出：新输入列表：

我用Google搜索并检查了很multithreading，但未能找到合适的解决方案。 但是当我在这个模型上使用Windows 8.1并安装synaptics触摸板驱动程序时，它的工作正常。 所以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提前感谢！

如果我确实理解你，那么Peter Hutterer的这篇文章可能会对你有所帮助。 T440跟踪点按钮支持似乎是一项正在进行的工作，目前更多的是一种解决方法。
他用ASCII艺术说明他们无法在Windows上配置触摸板：
+----------------------------+ | LLLLLLLLLL MMMMM RRRRRRRRR | | | | | | | | | | | | | | LLLLLLLL RRRRRRRR | +----------------------------+
并且必须配置触摸板按钮，如下所示：
+----------------------------+ | 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 | +----------------------------+
声明和当前的解决方法：
我正在为正确的配置制定解决方案，但是现在你必须满足于此。
本地配置最简单的方法是在表单中新的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把它放到
/etc/X11/xorg.conf.d/99-t440-synaptics.conf，你就可以了。
