What if you reboot now. You should be able to connect to the keyboard without stopping and starting bluetoothd. And you shouldn't need to repair. And you shouldn't need to click on connect. All you should need to do is turn on the external keyboard and press a (few) key(s) on the external keyboard. It should then connect (after a few seconds). The bluetooth symbol on the top of the screen should turn from white to blue. And you should be able to type. Then you can issue the setxkbmap command (and type a key on the internal keyboard) and it should work.

Can you verify this?
