Como ativar o bluetooth usando o Lenovo 480G

Question

Isso foi mencionado antes para diferentes modelos da Lenovo (aqui: Como habilitar o Bluetooth no meu Lenovo IdeaPad Z580? .

O interruptor de alternância é desativado, a ativação não faz nada, os diferentes tipos de comando da BT também não funcionam. Houve uma sugestão para atualizar o kernel para 3.7 * (estou executando o 3.6 * agora), mas quando fiz isso, não consegui descobrir como obter suporte de driver de rede com fio. Meu erro para obter uma Lenovo, parece bom, mas o suporte do Linux parece estar faltando.

Alguma sugestão de como ativar o Bluetooth?

Answer 1

Eu uso um Lenovo ThinkPad X200 Tablet e o Bluetooth está funcionando para mim. Talvez isso te ajude.

Eu uso bluez (4.101-r5) e faço o daemon iniciar no runlevel padrão pelo OpenRC. Para conectar dispositivos, eu uso o applet de gnome-bluetooth (3.6.1). Uma vez instalado, você deve adicionar uma seção "Bluetooth Settings" ao seu Gnome Control Center.

Aqui estão algumas informações adicionais.
