I have not been using my Ubuntu laptop touchpad for ages, but recently i have been traveling and i am taking my laptop out every day, so i have to use the touchpad way more frequently.
A wrench got thrown in my thinking process when i saw i cannot right click or edge scroll but it looks like this behavior was just changed. If it’s simpler or not it’s for you to judge:
Right clicking in Ubuntu is now achieved by using 2 fingers to click on the touchpad.
Edge scroll seem to not be working anymore, however you can scroll by using 2 fingers instead of one, anywhere on the touchpad.
