HD3200 Dual monitor xorg.conf
 

Hi,

I spent a long, long, LONG time getting my HD3200 integrated graphics to work with the ATI drivers.
My config: Asus M3A78-EM M/B, DVI 1920x1200, CRT 1600x1200, OpenSuse 11.1


Here's the xorg.conf:

And here comes the really magic trick that took me ages to figure out. You have to add the following lines to your .xinitrc for the dualhead to work:

xrandr --output DFP2 --preferred
xrandr --output CRT1 --preferred
xrandr --output CRT1 --right-of DFP2


Without that incantation you just get a clone display.


Hope that makes someone else's life much easier.
