如何减少所需的触摸板接触面积?

如何减少所需的触摸板接触面积?

我可以用拇指使用触摸板,但不能用短指使用。这似乎是因为手指与触摸板之间记录移动/点击所需的接触面积太大。我该如何解决这个问题?

xinput 的输出显示了三个指针设备:

Virtual Core pointer                        id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ AlpsPS/2 ALPS GlidePoint                  id=11   [slave  pointer  (2)]
⎜   ↳ ALPS PS/2 Device                          id=12   [slave  pointer  (2)] 

输出uname -r

3.16.0-45-generic

xinput内核升级后的输出:

emmanuel@emmanuel-HP-14-Notebook-PC:~$ xinput
⎡ Virtual core pointer                      id=2    [master pointer  (3)]

  • 这里的输出xinput list-props 11

输出dmesg | grep pnp

我对 ubuntu 社区提供的解决方案深信不疑,因为它适用于我的 ubuntu 14.04(在 hp14-notebookpc 上)。它只是调整灵敏度,如下所示,

打开终端并xinput list记下您的指针设备编号。

设置灵敏度:

应用xinput --set-prop [device number] "Synaptics Finger" 50 80 257(使用合适的值)。现在将重新调整灵敏度。设置的数字越高,触发事件所需的力度就越大。触摸板的灵敏度就越低。有关准确信息,请访问“https://help.ubuntu.com/community/SynapticsTouchpad“。
