I just bought a Gembird KB-BT-001-W Bluetooth Keyboard and I can pair and connect with it (after a few tries though, more often than not when pairing, after typing the numeric code it says pairing failed), but none of the keys are working. Except one: the backspace button does work.
I was running Ubuntu 16.04 and I just upgraded to 17.04 to see if that helped. It didn't.
It works fine under windows 10.
Any ideas on how to get the keyboard functioning properly?
