我的触摸板就像触摸屏一样工作

Question

所以我最近在我的 Alienware/Dell 上安装了 Ubuntu，一切都很好，直到我升级到 16.10。

\n

之后，我的触摸板突然开始像触摸屏（或图形输入板）一样工作，即指针跳到我在触摸板上触摸的任何位置（就像它映射到屏幕一样）。

\n

我尝试了我能找到的一切，即重新映射xinput甚至删除并添加鼠标模块psmouse，但没有任何效果。我找不到任何其他解决方案。

输出xinput

\xe2\x86\xb3 SynPS/2 Synaptics TouchPad就是我正在谈论的那个。

我还注意到人们遇到了与我相反的问题（即他们的触摸屏就像触摸板一样）

\n

请建议该怎么做。

Answer 1

没有安装用户空间触摸板驱动程序。这就是为什么它被视为相关设备的原因。

跑步

sudo apt install xserver-xorg-input-all

并重新启动会话。

如果您已经hwe-16.04安装了软件包，则需要运行

sudo apt install xserver-xorg-input-all-hwe-16.04
