[Bug 761236] Re: unable to correctly enable monitors connected to VGA

 

** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
- Same
+ To reproduce do following:
+ 
+ 1. Connect external monitor to VGA output.
+ 2. Launch gnome-display-properties and enable external monitors.
+ 3. At this point, both LVDS and external monitor should be working just fine.
+ 4. Using gnome-display-properties, turn off LVDS.
+ 5. At this point, the image in the external monitor looks like [1].
+ 
+ Note that this bug report was filed *while* LVDS was off and VGA1 was on
+ flickering as per [1]
