O meu som aqui também é via estou usando o Ubuntu 13.10 usei as dicas que não são para esta distro ainda e funcionou o post é do pessoal da Linux Sempre Up-Date, achei no google, para usar o linux tem que ler bastante e pesquisar e fuçar se der errado o negócio é persistir porque você só aprende e tem vantagens com relação ao windows.
