Buttons on my bluetooth headset aren't working

Solution 1:

As of Ubuntu 10.04, uinput module that handles such buttons is not started by default. To fix the situation:

  1. Stop bluetooth service
    sudo service bluetooth stop
  2. Enable uinput module
    sudo modprobe uinput
  3. Start bluetooth service back again
    sudo service bluetooth start

That should fix the issue temporarily, until restart. To fix it permanently, run:

echo 'uinput' | sudo tee -a /etc/modules
