我刚买了一台配备了突触触摸板的联想 T440s。默认情况下没有中间按钮，右键位于触摸板的右下角。我习惯了轨迹指针+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，因为按钮也是触摸板的一部分。
到目前为止我所做的是：
但问题是中间按钮没有映射到 trackpointer。在这个模型上，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：

我用谷歌搜索并检查了很多线程，但未能找到合适的解决方案。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。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！

如果我没有正确理解您，那么Peter Hutterer 的这篇文章可能对您有所帮助。T440 轨迹点按钮支持似乎正在进行中，目前更像是一种解决方法。
他用 ASCII-art 说明他们不能像在 Windows 上那样配置触摸板：
+----------------------------+
| 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：
我正在研究正确配置的解决方案，但现在您必须对此感到满意。
最简单的本地配置方法是一个新的 InputClass 部分，形式如下：
Run Code Online (Sandbox Code Playgroud)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，你就可以开始了。
