我在 Acer Swift SF314-42 上运行着 Ubuntu 22.04
触摸板一直运行正常，但今天不行。几天前，我的键盘上落了几滴小雨滴，我立即用厨房用纸擦干，而且雨滴很少，所以我乐观地认为这无关紧要。
我尝试重新启动，尝试了 Wayland 和 Xorg，但遗憾的是，无论哪种方式，触摸板都没有任何反应。
除了触摸板之外，我还有一个罗技 M525 鼠标，它仍然可以正常工作。
我已经对如何诊断问题进行了一些 DuckDucking 操作。以下是摘录自：

运行 Xorg 时，xinput list 显示以下内容

这一页：https://unix.stackexchange.com/questions/400153/how-to-find-logs-about-touchpad-malfunction-in-debian-on-wayland 说服我尝试“evtest”，我必须使用以下命令安装：
sudo apt install evtest
Evtest 会显示输入设备列表，要求您选择一个，然后显示支持的事件，然后显示该设备的实际事件。对我来说，Touchpad 是 10

触摸触摸板不会产生任何事件。
相比之下，如果我选择 Logitech 鼠标 7，我会看到鼠标移动事件，BTN_LEFT 和 BTN_RIGHT。
我看了一下 BIOS，但没有看到任何关于启用/禁用触摸板的内容。
有什么想法可以让触摸板开始工作或者什么可以阻止触摸板事件发生？
