I have a strange problem with my xserver.
A few days ago I changed my resolution from 1024x768 to 1280x1024. I edited xorg.conf for this. However, after restarting the xserver, GDM only uses a part of the screen (i think 1024x768), the rest is just flat color. After logging in in Xfce, there are also problems. My panel was half way on my screen (again in the bottom of a 1024x768 box). I can't make my windows larger than 1024x768.
My xorg.conf file without the comments.

I have never seen a problem like this before? What's the problem? I'm running the fglrx drivers from ATI.
Edit
A few other problems: In xfce I can select backgrounds for 2 monitors. When I change it for monitor 1, i get a small background (the well known 1024x768) in front of the background I choosed for monitor 2.
