我刚买了一台配备 Synaptics 触控板的联想 T440s。默认情况下没有中间按钮，右按钮位于触控板的右下角。我习惯了触控点 + 左/中/右按钮的组合，我真的很怀念我的新型号。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。
我目前所做的是：
- 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/右键功能
- 按预期在触摸板上定义中/右按钮区域
但问题是中键没有映射到 Trackpointer。在这个型号上它们似乎是两个独立的设备。我想知道如何将中键触发的事件连接到 Trackpointer 的滚轮模拟按钮。
这是我的 xinput 属性的输出： Xinput 列表：

我搜索了一番，查看了很多帖子，但还是没能找到合适的解决方案。但是当我在这个型号上使用 Windows 8.1 并安装 Synaptics 触摸板驱动程序时，它运行正常。所以另一个建议是将该驱动程序移植到 Linux。
任何帮助都将不胜感激，提前致谢！

更新 4：解释原因新一代的物理按钮可能同样有问题与上一代产品一样，没有实体按键
如果我理解正确的话，那么这篇文章由 Peter Hutterer 撰写可能会对你有帮助。T440 指点杆按钮支持似乎还在进行中，目前更像是一种解决方法。
他用 ASCII 艺术说明他们无法像在 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 |
+----------------------------+
声明和当前的解决方法：
我正在努力寻找正确配置的解决方案，但现在你必须对此感到满意。
本地配置最简单的方法是新建一个 InputClass 部分，形式如下：
Section "InputClass" Identifier "t440 top buttons" MatchDriver "synaptics" # right btn|middle btn Option "SoftButtonAreas" "60% 0 0 0 40% 60% 0 0" EndSection将其放入
/etc/X11/xorg.conf.d/99-t440-synaptics.conf，您就可以开始了。
