Nenhum adaptador Bluetooth encontrado após a instalação do 14.04 sobre o Zorin OS

Question

Eu estava usando o Zorin OS 5 no meu Compaq Presario 510 e, naquela época, meu Bluetooth embutido estava funcionando perfeitamente, mas depois que eu instalei o Ubuntu 14.04 ele diz

  

não foram encontrados adaptadores de Bluetooth.

Eu consegui reproduzir isso reinstalando o Zorin 5 (o Bluetooth funcionando novamente) e, em seguida, reinstalando o Ubuntu 14.04 (nenhum adaptador Bluetooth encontrado).

Answer 1

Eu finalmente tenho o Bluetooth ativado e consigo encontrar meu dispositivo Android e parear com ele.

Eu inicializei o disco do instalador do Zorin 5 e selecionei para executar ao vivo sem instalação. O ícone do Bluetooth no painel inferior estava mostrando que o Bluetooth estava desligado, liguei e estava funcionando, consegui encontrar dispositivos Bluetooth.

Eu saí do Zorin 5 ao vivo desligando-o com o Bluetooth ligado, removi o disco do instalador e liguei meu laptop novamente. Bluetooth no meu Ubuntu 15.04 começou a funcionar. Eu poderia emparelhar com ele e compartilhar arquivos.

Não consigo usar meu dispositivo Android para fazer a rede através do Bluetooth, o que consegui fazer no Zorin, e não consigo transferir arquivos grandes (mais de 5 MB), mas estou feliz.
