16.04 Não é possível ativar o bluetooth [duplicado]

Question

Eu tentei ativar as configurações, fazendo sudo /etc/init.d/bluetooth start , sudo /etc/init.d/bluetooth restart , rfkill list says

2: hci0: Bluetooth
Soft blocked: no
Hard blocked: no

Eu tenho rfkill unblock bluetooth em rc.local, mas ele não liga. Se eu tentar habilitá-lo através da caixa de seleção das configurações a caixa de seleção muda de estado, mas o texto "bluetooth está desativado" ainda está lá. Btw, sim, eu verifiquei duas vezes que eu não desabilitei com botão de hardware. Como faço o bluetooth funcionar no 16.04?

Answer 1

Você pode postar a saída de dmesg | grep Blue e lsusb -t .

Além disso, pode ser algo tão simples quanto incompatibilidade com o Unity, tente executar:

sudo apt-get update
sudo apt-get -y install unity-control-center
