触摸板联想 P14s 20.04 LTS 停止工作

本周，我在联想 P14 上安装了 Ubuntu 20.04 LTS。最初，包括触摸板在内的所有东西都可以开箱即用。但今天，我的触摸板停止工作了。因为在另一个论坛上有人问了这个问题，试图提供帮助的人要求新输入和xinput 列表属性“SynPS/2 Synaptics 触摸板”（提问者没有进一步回复），我想在这里做同样的事情。

$ xinput

PS：我不明白是什么解决了这个问题这个问题。我尝试关闭我的 MX Master 3，但对触摸板没有影响。

答案1

同样在这里。

过了一段时间，触摸板停止工作。但是，按钮和旋钮仍在工作。当我将 BIOS 的配置更改为使用粘性 Fn 键时，我发现了这个问题。我还将 Fn 换成了 Ctrl。我不太习惯新的配置，所以我不小心按下了 Ctrl（Fn 功能）和 +V。之后（我正在用 vim 编写一些代码），v 字母开始一直打印，触摸板停止工作。

重新启动解决了这个问题，但我尝试使用kill -9命令终止该进程。尽管命令已处理，但 Ubuntu 并未终止它。

重启后，正如我所说，一切都正常了。但是我发现这个登录dmesg
