启用触摸板压力检测

我的触摸板上有很多错误的点击，导致我拖动东西并点击我本来不想点击的东西。我认为原因是压力检测（我假设我的触摸板有）不受支持。我可以做些什么来启用它？

$ libinput measure touchpad-pressure 
Using SYNACD3E:00 06CB:CD3E Touchpad: /dev/input/event6

This device does not have the capabilities for pressure-based touch detection.
Details: Device does not have ABS_PRESSURE or ABS_MT_PRESSURE

我目前已停用点击拖动功能，但这是我经常使用的功能，但我仍然会收到虚假点击。

我有联想 IdeaPad S540 和 libinput 版本 1.15.5。

有没有什么方法可以安装正确的触摸板驱动程序或我可以做其他什么来获得压力或尺寸检测？

就我而言，通过切换到 synaptics 解决了这个问题：

sudo apt install xserver-xorg-input-synaptics

（然后注销并重新登录。）

未经测试：另一种选择是：

sudo apt install xserver-xorg-input-evdev
