LVDS connect Issue. (Se VGA conectar. LVDS desligado)

2

Eu tenho um problema muito difícil.

E eu não soluto não encontrei uma solução para este problema durante 3 semanas.

Agora testou o sistema operacional (ubuntu 14.04, ubuntu 12.10, ubuntu 12.04) mesmo problema.

VGA e LVDS conectados fisicamente. Mas se o VGA estiver conectado, a tela LVDS será desligada.

Eu não sei agora por que esse problema.

alguém ajuda

5. Log :
    I think this line very strange. Why disconnected LVDS?

[    10.813] (II) intel(0): Output VGA1 connected
[    10.813] (II) intel(0): Output LVDS1 disconnected
[    10.813] (II) intel(0): Output TV1 disconnected
    If you need to all log. I will post that. that's very long.
