Currently if i press Super+Space, gnome desktop will pop up 2 language selections set by Input Sources from gnome-control-center. Then why not it pop up 3 languages selection set by Input Method section from ibus-setup instead ? What's the difference between both ? My platform is Kali Linux 2016.2, GNOME Shell 3.22.0, and IBus 1.5.11.
