跟踪点和按键:启用按钮和滚动(联想T440s)
我刚买了一台联想T440s，它配备了synaptics触摸屏。默认情况下，没有中间按钮，右边按钮位于触摸屏的右下角。我已经习惯了轨迹指针+左/中/右按钮的组合，我真的很怀念我的新型号。每次我按下按钮时，它都会产生一些噪音，因为按钮也是触摸屏的一部分。
到目前为止我所做的是：
- 增加触摸屏的迟滞到非常高的值，这实际上是禁用了导航。
- 启用键盘模式，它提供中/右按钮的功能。
- 按预期在触摸屏上定义中/右按钮区域。
但问题是，中间按钮没有映射到跟踪指针。在这种模式下，它们似乎是两个独立的设备。我想知道如何将由中间按钮触发的事件连接到track指针的轮模拟按钮。

任何帮助都将不胜感激，提前感谢！

...这一次的支持是真实的，或者至少接近完成。...我忘了提到:Synaptics1.8将拥有所有这些...
更新2:上面的帖子更新了，diff：http://who-t.blogspot.de/2014/04/t440-touchpads-story-continues.html
更新3: Bj rn Tillenius编写的支持在Ubuntu中为联想的按键进行中间滚动
更新4:解释为什么新一代的物理按钮可能也被破坏了。是上一代的非物理按钮
如果我对你的理解是正确的，那么这篇文章是彼得·哈特雷写的可能对你有帮助。支持T440跟踪点按钮似乎是一项正在进行的工作，目前更多的是一种解决办法。
他用ASCII-art说明，他们不能像在Windows上那样配置触摸屏：
+----------------------------+
| LLLLLLLLLL MMMMM RRRRRRRRR |
| |
| |
| |
| |
| |
| |
| LLLLLLLL RRRRRRRR |
+----------------------------+并且必须像这样配置触摸屏按钮：
+----------------------------+
| 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 |
+----------------------------+语句和当前解决方案：
我正在为正确的配置制定解决方案，但现在您必须满足于此。本地配置的最简单方法是表单中的一个新的InputClass部分："InputClass“标识符"t440顶部按钮”、“MatchDriver "synaptics”#右btn \中间btn选项"SoftButtonAreas“60% 0 0 40% 60% 0”EndSection将其放到
/etc/X11/xorg.conf.d/99-t440-synaptics.conf中，这样就可以了。
