几个月前我从戴尔购买了一台新笔记本电脑，即戴尔 Latitude 3510。它附带 Ubuntu 18.04，我已将其移除并安装了 Ubuntu 20.04 LTS。
问题是触摸板会突然停止大约 5 到 10 秒，然后又自行工作。它还可能突然加速并无缘无故停止滚动，当我尝试关闭触摸板时，它不会关闭。解决问题的唯一方法是暂停 Ubuntu，然后再次打开它。
键盘还可以执行一些随机操作，例如自行输入关键字以及在书写时移动光标。
我知道这里有很多关于类似问题的问题。但相信我，我尝试了这里的每一个答案，并且搜索了一个多月。我发布这个问题是因为我真的没有找到任何解决方案。
当我运行xinput list它时输出：
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ DELL09ED:00 27C6:01E0 Mouse id=10 [slave pointer (2)]

然后运行后input list-props "DELL09ED:00 27C6:01E0 Touchpad"：
