I have recently been experimenting with Linux on convertible tablets to replace my Chromebook, and after some distro-hopping found Fedora Gnome to be the best for screen rotation, trackpad, and touchscreen support. However, I am constantly frustrated with the inconsistency between gestures on trackpad vs. touchscreen. I have seen the same behaviour both on a Dell Latitude 5290 2-in-1 (not the laptop with the same model number) and Surface Go 2 (using the default kernel not surface-linux).
In essence, the gestures to open the Activities Overview and switch Workspaces use 3 fingers on a trackpad but require 4 fingers on the touchscreen.
In my quest for a solution to this inconsistency I have found zero solutions and 3 separate pages on gnome.org which give differing information about gestures. I have opened an issue on Gitlab for the documentation to be corrected, but I am posting here in the hope that someone has a solution that will let me change the gesture behaviour to be consistent between trackpad and touchscreen.
How do I make touchscreen gestures also use 3 fingers to open the Activities Overview and switch workspaces?
