ATI Big-Desktop and RandR

Hi everyone.
I am running the ATI hd 2600 pro card and using the ATI propietary driver.
Since I got arch up and running with GNOME and the propietary driver I have been using the command below to use dual screens.

xrandr --output DFP2 --left-of CRT2

The problem is it does not behave the way I am used to with the ATI Big-Desktop that I have used on Ubuntu. (such as when maximizing windows it covers both screens completely or having a seperate application panel for each screen)
So my real problem is that when trying to get ATI Big-Desktop working using this guide I get this error.

[fultonla@archlinux ~]$ sudo aticonfig --desktop-setup=horizontal --sync-vsync=on --add-pairmode=Width0xHeight0+Width1xHeight1
Xlib:  extension "Generic Event Extension" missing on display ":0.0".
Xlib:  extension "Generic Event Extension" missing on display ":0.0".
Xlib:  extension "Generic Event Extension" missing on display ":0.0".
Error: Options, e.g. --dtop and --desktop-setup, are not supported when RandR 1.2 is enabled!
Xlib:  extension "Generic Event Extension" missing on display ":0.0".
Error: pair mode is not supported when RandR 1.2 is enabled!
Warning: Option 'Capabilities' doesn't affect running session.
Using /etc/X11/xorg.conf
Saved back-up to /etc/X11/xorg.conf.fglrx-14

What is RandR used for? Is it important? If not how can I disable it?

Any help is appreciated

Re: ATI Big-Desktop and RandR

You have two possibilities: either you use xrandr + radeon or radeonhd driver or you use fglrx + aticonfig. You cannot mix both.

I'm not sure what you mean?
Are you saying I'm not in fact using fglrx with my current configuration?

Re: ATI Big-Desktop and RandR

he means that fglrx doesn't support xrandr.

Ok I understand that but how do I disable it?
I removed xrandr --output DFP2 --left-of CRT2 from my startup and it nstill gives me that error :S
