Eu instalei pela primeira vez o Ubuntu em um computador. Tudo funcionou perfeitamente até que eu tentei ligar meu teclado bluetooth ao meu computador e notei que não consegui encontrar nenhum dispositivo bluetooth. Eu tentei telefones, fones de ouvido, outro computador ...
Eu tentei muitas respostas pela Internet, mas ninguém conseguiu resolver meu problema.
