I’ve been using Arch on my XPS 2015 edition since the very beginning. Not only was the support of the software components newer/better than Dell’s official Ubuntu version for the developer edition, but also I absolutely love the rolling release before it was cool.
So as we are bleeding edge, sometimes things break. Arch moved over to wayland some time ago, but like two days ago my touchpad’s right & middle click stopped working. Quick google search later revealed, that my gnome settings had the following option set to ‘fingers’. That didn’t work as my XPS has ‘areas’ – so switching it over with this simple command, fixed things for me.
gsettings set org.gnome.desktop.peripherals.touchpad click-method 'areas'
