I know that you can set the touch pad to scroll on the right side, but is it possible to scroll left and right? I mean, when there are websites that require side scrolling, is it possible to swipe on the top or bottom of the touch pad?
Yes. Open Systems settings then click "Mouse and Touchpad"
Open the touchpad tab and then enable both "two finger scrolling" and "horizontal scrolling"
I actually disabled this feature after trying it for a while because I found it annoying if the screen scrolled horizontally when all I wanted was a vertical scroll.
