amigos, estou trabalhando há dois dias, tento fazer alguma coisa em fóruns nacionais e estrangeiros, mas não consegui. Eu apreciaria se você pudesse ajudar.
a) Instalei atualizações.
b) pode se conectar a um cabo
c) Instalei o Windows 7 lado, funcionando wireless conforme digitado no windows
d) A tecla fn + f3 para abrir wireless que não funciona, não liga quando o wireless sinaliza o ubuntu.
desligar a tela do computador mostra:
ubuntu 14.04
..... reboot: system halted
*stopping rsync daemon rsync [OK]
*speech-dispatcher disabled ; edit/etc/default/speech-dispatcher
*asking all remaining processes to terminate... [OK]
