Kubuntu 17.04 上的触摸板突然停止工作

我已经使用 Kubuntu 17.04 几个月了。今天，当我启动电脑时，触摸板无法使用，我不知道为什么。

我在 Google 上搜索了一段时间，发现很多人因为不同原因遇到这个问题，但还没有找到适合我的解决方案。这不可能是由于新软件安装或升级造成的，因为我昨天（上次成功时）没有安装任何软件。今天重启电脑也没有改变任何东西。我还检查了笔记本电脑上的触摸板切换按钮，但没有结果。

显然系统正在识别触摸板：


dmesg |grep -i touchpad

以下是输出xinput

我尝试跑步synclient TouchpadOff=0，但什么也没改变。

我还可以检查/尝试什么？谢谢！

答案1

事实证明我比我想象的还要笨。我的笔记本电脑有两个不同的按钮可以切换触摸板（一个是 Fn+F9，这是我尝试的，另一个是触摸板上方的一个稍微显眼的小按钮）。按下第二个按钮就可以了。
