Dual-screen setup on a Mobility FireGL 7000M7

[Ludwig Meyerhoff]

Hallo!

I forgot ...

The :0.0 screen uses VGA-0, :0.1 uses LVDS and is completely blank 
(black screen, just the backlight is on).

When I change to text-mode (VT1), the LVDS is still blank.

Even when I disable the 2nd screen in xorg.conf and restart the server, 
LVDS does not show any image.
In order to have an image on LVDS again, I have to reboot the machine.


Saluti!
