--- Comment #1 from Daniel Vetter <daniel at ffwll.ch> ---
Atm we don't support atomic modeset, so you X does changes step-by-step. Which
means in-between it'll try to enable 3 outputs which won't work. If you split
up the operation into 3 steps

1) Enable 1st external screen
2) Disable internal screen
3) Enabel 2nd external screen

it should work. Closing as not a bug, simple a misdesign of the current code.
