Выпуск LVDS подключения. (Если VGA подключиться. LVDS выключен)
У меня очень тяжелая проблема.
И я не решаю, что не нашел решения этой проблемы в течение 3 недель.
Теперь тестируемая ОС (Ubuntu 14.04, Ubuntu 12.10, Ubuntu 12.04) та же проблема.
Физически связаны VGA и LVDS. Но если VGA подключен, экран LVDS выключен.
Я не знаю, почему эта проблема.
кто-нибудь поможет

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.
