[Solved] Dual Head problem (ATI)

[Delphi]

I have a kind of interesting problem when trying to set up dual head on my computer. I followed the steps to editing my xorg.conf on the Gentoo Wiki (gentoo-wiki.com/HOWTO_Dual_Monitors). I have managed to almost set up dual head; it is working on the login screen, but it reverts back to both monitors showing the same image (clone mode, i guess) the instant KDE starts to load. Also if I run $startx from the console in recovery mode, when I am logged in as root, everything works perfectly.

Does anyone know how I can make dual head work when I am logged in as a normal user? Or could you at least point me in the right direction?

My graphics adapter is an ATI Radeon 9600 using the proprietary ATI drivers, and both the monitors are ViewSonic VG2230wm.

Also, since I guess my xorg.conf is needed if I am to get any meaningful help, here is it

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#

Re: Dual Head problem (ATI)

I managed to get it working, partly due to reading posts on Linuxguestions.org, and partly because of guesswork (not too much of the latter though )

What I did, was to first issue

aticonfig ---initial=dual-head/code]
 
And then adding 
[code]Option "Xinerama" "on"

to my xorg.conf

I don't know if this is the 'correct' way to to it, but it is working now, and hopefully this post may help someone else later.
