我正在尝试在东芝 Tecra A40(ALPS 触摸板)上使用 Ubuntu 16.04,但遇到了以下问题:
当使用双指滚动功能时,上下文菜单(即右键单击)也会持续激活,直到我“取消触摸”触摸板。
这意味着如果不打开多个新标签,几乎不可能滚动网页(例如)......
我已经尝试过 Ubuntu 14.04、16.10 和我想要的版本 16.04 LTS。
奇怪的是,在安装之前,实时版本(直接从 USB 映像)不存在此问题。但在安装过程之后,我尝试的每个版本都出现了此问题。
有人能给我一些指点,告诉我该怎么做才能追踪这个问题并解决它吗?
谢谢。

问题是,当我将两根手指放在 TouchPad 上时,它会做出“点击”的反应并检测到右键单击。无论我使用什么应用程序(任何浏览器、LibreOffice 等),这都会导致两指滚动无法使用。
任何帮助都欢迎。
谢谢
