Perdeu a funcionalidade do bluetooth após a atualização de 17.04 para 17.10

Question

Um dia atrás ou antes de atualizar de 17.04 para 17.10, consegui conectar meu computador com meus fones de ouvido via bluetooth. Agora eu não posso. Eu pensei que talvez eu precisasse instalar o Bluetooth Manager e o Adaptador Bluetooth do Gerenciador de software, mas isso não ajudou. Alguém pode sugerir algum código que eu possa usar através do terminal para reinstalar os drivers bluetooth ou o que não está funcionando para que eu possa voltar a usar a função bluetooth no meu computador? Nas configurações, Bluetooth, diz que conecte um dongle para usar o bluetooth agora. Não disse isso antes.

Answer 1

Eu atualizei o Kubuntu de 17.04 para 17.10 ontem.

Principalmente o mesmo problema para mim, não consigo mais conectar meu alto-falante bluetooth (RYGHT TANK), embora meu serviço bluetooth esteja em execução.

Aqui estão os meus resultados sudo service bluetooth status e dmesg | grep -i blue :

Uma tela de impressão da mensagem depois de tentar se conectar: falha na conexão

Alguma ideia?

EDIT (11/05 entendi!): Acabei com uma solução:

sudo apt install kmix
reboot

então

sudo apt install pulseaudio-module-bluetooth
reboot
pactl load-module module-bluetooth-discover

(último comando pode falhar)

Em seguida, remova todos os seus dispositivos Bluetooth salvos e os emparelhe novamente.

Não se esqueça de definir os dispositivos bluetooth no topo da lista de configurações de áudio:
