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)]
⎜ ↳ 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)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ HP Truevision HD id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ HP WMI hotkeys id=13 [slave keyboard (3)]
↳ HP Wireless hotkeys id=14 [slave keyboard (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“。
