Estou usando o laptop Dell Vostro 3750 com 2 monitores. OS Kubuntu 13,04
1 monitor eu conectei com VGA e está funcionando bem. Mas outro monitor conectado à porta HDMI não é detectado. Eu conectei o monitor HDMI ao meu laptop amigos com o Windows 7 e funciona bem. mas apenas com o Ubuntu não está funcionando.
