現象

Did the right click on your touchpad stop working after installing Ubuntu 18.04 LTS?


The touchpad right click may not function on your computer after installing Ubuntu 18.04 LTS.

原因

This is not an issue with the operating system or your touchpad. Gnome defaults to the Mac touchpad behavior where the entire touchpad is a single button. In order to right-click, you use two fingers to click instead of one.
