Lenovo x1 gen9 @ ubuntu22 - 触摸板太敏感而无法触摸

我有一台 Lenovo X1 gen9，上面装有 Ubuntu 22。触摸板太敏感，当我移动光标时，经常会拖动东西，记录错误的点击和双击。我发现解决方案是使用 xinput 但我找不到我必须更改的内容。

这是我的xinput list-props <device id>输出：

在终端中运行此命令来查找触摸板的 ID 号

xinput --list

从例子来看我的是12

DELL097D:00 04F3:311C 触摸板 ID=12 [从指针（2）]

然后设置滚动速度（将 12 更改为您的触摸板 ID 号）

input --set-prop **12** "libinput Scrolling Pixel Distance" 50

注意更高数字使滚动慢点

我不知道如何更改默认值...有一种方法可以使用 xorg conf 文件保存它，但我不知道如何...也许有人可以添加/编辑这个答案
