Touchpad按钮不工作在联想Yoga 2-11与Ubuntu 20.04.4

Question

我决定把Ubuntu安装在我的旧联想瑜伽2-11上。与Windows相比，这在性能上产生了巨大的差异，但还有最后一件烦人的事情我无法修复。按钮集成在触屏的下部不起作用。知道能不能修好它们吗？我试过像其他线程中建议的那样使用邪恶的工具，但是没有运气。

在选择设备4并按下按钮后输出(虽然我有感觉evemu正在检测到我触摸到了触摸屏，而不是我按下了按钮所在的下边)

你的设置不对

Click Method Enabled (331):    0, 1

这个设置的意思是“纽扣指”

默认设置为

Click Method Enabled Default (332):    1, 0

设置为“纽扣区”。

您已经在某个地方更改了默认设置。

跑

 xinput set-prop 14 331 1 0

并测试它是如何工作的。
