For now, you’ll have to hack /usr/lib64/gnome-shell/libgnome-shell.so … edit with a hex editor
Find this “GESTURE_FINGER_COUNT = 3” … change 3 to 4. or maybe change in to 5 to disable swiping in the shell.
I have some scripts to hammer gnome-shell to my liking: 4 finger swipe, custom gdm login wallpaper, and a quick dash-to-dock fix.
