A janela do gerenciador Bluetooth não abre

Question

Estou usando um dongle USB Bluetooth no meu Raspberry Pi. Até agora eu consegui conectar o dispositivo e emparelhá-lo usando o terminal. No entanto, o gerenciador de desktop / GUI Bluetooth não abre. Eu posso ver o ícone na área de trabalho e como você pode vê-lo, posso até clicar com o botão direito do mouse para opções, mas nenhuma delas é aberta. Eu tentei tudo descrito aqui sem sucesso. Alguma idéia de por que isso acontece e como eu posso consertar isso?

UPDATE: seguindo a sugestão do @ Patrick, eu fiz um pkill blueman-applet e blueman-applet e obtive a seguinte saída:

pi@raspberrypi ~ $ pkill blueman-applet
pi@raspberrypi ~ $ blueman-applet
Xlib:  extension "RANDR" missing on display ":1.0".

Answer 1

Isso não é realmente uma correção, mas tente clicar em "Desligar o Bluetooth". Em seguida, tente abrir o gerenciador do bluetooth. Ele deve solicitar que você ligue o bluetooth novamente e, em seguida, o gerenciador abrirá. Isso funcionou para mim.

    

Answer 2

Eu tive o mesmo problema (como observado no comentário acima). Estou usando o adaptador Bluetooth Plugable USB-BT4LE em um Pi 2. Esta página ( link forneceu a resposta:

If the Bluetooth utility does not see the Bluetooth adapter try the following commands:

sudo nano /etc/group

{change line 8 from “lp:x:7:” to “lp:x:7:pi” save and exit}

sudo reboot

Isso fez o truque para mim!
