HP 2000 笔记本电脑触摸板在 Ubuntu 和 Windows 中无响应;外接鼠标工作正常

我的 HP 2000 笔记本电脑的触摸板一直存在问题,该笔记本电脑双启动了 Ubuntu 20.04 和 Windows 7。触摸板没有响应,没有记录任何点击或触摸,因此无法使用。有趣的是,当我在安全模式下运行 Windows 7 时,触摸板问题暂时得到解决,但问题最终再次出现,安全模式无法再修复。

我的 HP 2000 笔记本电脑上的触摸板在 Ubuntu 20.04 或 Windows 7 中均无响应。我无法使用它进行导航或单击。奇怪的是,外接鼠标工作正常。当我在安全模式下运行 Windows 7 时,该问题最初得到修复,但这种解决方法不再有效。这让我相信问题可能与硬件无关。即使 Ubuntu 在闪存驱动器上实时运行,问题仍然存在。
