Touchpad gestures for Linux apps are being worked on: - Latest update (December 2021): https://www.gitclear.com/blog/linux_touchpad_update_december... - HN: https://news.ycombinator.com/item?id=29555822 So far, pinch-to-zoom has been implemented in Firefox. (If you are using X11 instead of Wayland, then the environment variable MOZ_USE_XINPUT2=1 needs to be set.) Gestures for back/forward navigation have not been imp…
What I don't quite get is why this needs a project; it just needs configuration options; for example, two-finger swipes currently map to mouse buttons (buttons 6 and 7 for left/right swiping) which most apps interpret as scrolling (in every direction). I'm about to write a script to remap those to browser back and browser forward actions (after a delay to prevent repeated actions), but I'm so surprised it's not baked…
If this was MacOS, I'd agree. But on Linux, it's a different hardware landscape. There are hundreds of trackpads that Linux is compatible with, but not every one of them is multitouch (or implements multitouch the same way). Gesture support on Linux has been a long time coming, but that's mostly because getting uniform trackpad support over thousands of laptops is just not a very fast process, whereas on MacOS, Apple can make certain assumptions about the hardware it's running.
