Fedora 16 :intel 945GM on Macbook2,1

[psicfr]

Hello,

I've juste installed a new XFCE Fedora 16 on my macbook(early 2006). I only can run with a low resolution 1024x768 wich is for 2/3 screen but I can not adjust my display setting to a 16/9 resolution.
I have a intel 945GM, and I do not know what to do ?

I use 915 resolution.

Create a /etc/rc.d/rc.local with

/usr/sbin/915resolution 38 1280 800

and it's ok.
