If you are still using the Jollaphone (the first one) with a tohkbd2 keyboard, the keyboard does not wort after the upgrade to 3.4.0.22EA. To make it work again open a terminal and enable and start some services:
devel-su systemctl enable tohd
devel-su systemctl restart tohd
devel-su systemctl enable harbour-tohkbd2
devel-su systemctl restart harbour-tohkbd2
After this it should work again.
