Use libinput-gestures or... Wayland.
It looks like libinput-gestures is similar to touchegg/touché in the sense that it only adds support for 3 or 4 finger gestures. It looks like 2 finger gestures are supposed to be supported by your DE or are app specific.
Thanks for the reply!
I suppose, but a three finger swipe still only needs one hand (I think it is the same on macbooks) so should work fine.
That implies that it already existed in X11 environments?
Not necessarily. Especially in the gestures department, those tend to be Wayland exclusive and is probably why you need to press Alt on X11. I think applications pretty much only get scroll wheel events on X11, while on Wayland they get proper touch events so it's possible to also implement pinch to zoom and the other usual ones.
Both Gnome and KDE only support 3-4 finger gestures on Wayland as well, like 3 fingers up for overview in Gnome just like macOS.
I would expect Wayland to work great on a Chromebook, I'd recommend giving it a try.
I would love to run gnome/wayland, but my Chromebook is about a decade old, and it was a cheapo from the start. It only has 2GB ram, so I’m running as light as I can. Unless there is a way to put wayland on xfce, I might be stuck. I appreciate the reply!
