I bought a bluetooth keyboard (which works perfectly fine on windows) and all the keys are either jumbled or not working at all. It worked fine on ubuntu as well until I pressed the num lock key and ever since then it stopped working. I even tried to reset the keyboard by removing the battery but nothing helps.
The keys that do work are the num pad keys with the fn key, backspace, = (which is mapped under the - key) and the special function keys (such as volume mute/up/down (F10,F11 and F12 respectively), brightness (F5 and F6) etc (all of which are not in accordance with the hardware layout)

Does anyone know how to fix this?
It's a maxxter act-kb-bt-001 keyboard that requires a pin to be typed upon connecting. I can connect with bluetoothctl and it shows me this info but the jumbled keys problem persist.

Default for ubuntu sessions is numlock on.

To make the default numlock off so your keyboard works:

sudo apt-get install numlockx

...then go to Startup Applications Preferences and add a new entry:

  • Thanks mate but it was the keyboard. I switched it for another model and it works perfectly now.
