The touchpad on my current gen Dell XPS 13 is superb on a stock Ubuntu install. I'd love to know how much of the "bad touchpad" reputation that Linux has is down to low quality hardware versus software support.
On the other hand touchscreen is really disappointing on Linux (Ubuntu), just not a smooth experience at all for me.
I get the same feeling with high vs low quality touchscreens (e.g. my phone vs some ATMs), and especially with gaming controllers. With a good, ergonomic controller I sort of forget about the shape and weight of the controller in my hands after a while; my entire sense of it narrows down to the buttons/triggers/joysticks.
Last time I used Linux on my MBP, libinput was more... linear.
I’d love to contribute to this project, but I’m not sure how.
