[Bug 697037] [NEW] Internal laptop monitor blank when external not plugged in

 

Public bug reported:

Binary package hint: xorg

On a samsung V25 laptop the screen does not work unless an external monitor is plugged in. Without an ext monitor the system starts and the screen turns off. I can change to a text only console using the normal keystrokes.
When an external monitor is plugged in I can get 1024x768 display on both monitors.
