Pb with second screen on an Acer iconia 484G64ns

[Mathieu Magnaudet]

Hello

I'm trying to install a Fedora (beta 16, kernel 3.1) on an Acer Iconia 
484G64ns (laptop with 2 touch screens). It works fine on the first 
screen but there is no display on the second one.
I have tried to activate it via xrandr --output LVDS2 --below LVDS1 but 
it doesn't work. It is still seen as "disconnected". Any idea?
