Please Help With Dual Head



Greetings:

I recently upgraded my os (a clean install) to Fedora Core 5, and I was excited to see the support for Dual Head built into the configuration utility. I am having a problem getting it setup correctly. What I want is to extend my desktop onto my second monitor. I went through the System->Administration->Display utility and can't make it work. I will describe what is happening.

I have 2 identical monitors and a Radeon X600 PCIE card. When I boot to windows the setup works so it is plugged in correctly. The monitors are connected via the digital hookup.

On my left monitor I have a desktop. Then on my right monitor I have a ghosted image from the left monitor. If I try to click on the left monitor it doesn't work (I can move the mouse onto screen1 by going off the right edge of screen 0. I noticed by looking at the workplace switcher I actually have the wide desktop. I can move windows on and off the part which lies underneath the ghosted image of screen1. So in short, everything is correct except Screen1 shows an image of Screen0 instead of the desktop which is really there.

I am a bit frustrated as I have been tinkering with xorg.conf and can't make it work. This used to work so I feel like it still should, if anyone could give me some tips or something I would greatly appreciate it.

I will include my xorg.conf just for completeness

# To customise the XKB settings to suit your keyboard, modify the

# keyboard, you will probably want to use:
#    Option    "XkbModel"    "pc102"
# If you have a US Microsoft Natural keyboard, you can use:
#    Option    "XkbModel"    "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
#    Option    "XkbLayout"    "de"
# or:
#    Option    "XkbLayout"    "de"
#    Option    "XkbVariant"    "nodeadkeys"

# If you'd like to switch the positions of your capslock and

# Or if you just want both to be control, use:
#    Option    "XkbOptions"    "ctrl:nocaps"
