Dual Monitors Radeon 9200

I just upgraded my system to FC2 and I am trying to get dual monitors working. I have a a Dell 4600 with an on-board video built in to the workstation using the i810 driver and just installed a Radeon 9200 PCI video card. I have two monitors. I can get one set or the other working, but not both. Anyone else done this? I tried everything using the display program, I tried downloading the radeon rpm called xfglrx-4.3.0-3.14.1.i386.rpm and running fglxconfig, but that only crashes my X server.

Any help would be greatly appreciate.

first of all... is your radeon one of those with two outputs? or are you using two video cards?

with two cards, the way to use dualmon in linux is through an option called Xinerama. google it and it will give you instructions. since you have gotten them both working separately, it should be a fairly simple process to get Xinerama working.

I have a pci and an agp video card. this is what my XF86Config-4 looks like:
Section "ServerFlags"
#the tildes are where I omitted junk like keyboards
      Option "Xinerama" "true"
Section "Monitor"
       Identifier  "My Monitor"
       HorizSync   31.5 - 79.0
       VertRefresh 50-90

Section "Monitor"
	Identifier	"monitor2"
	HorizSync	31.5 - 79.0
	VertRefresh	50-90

Section "Device"
    Identifier	"S3 ViRGE"
    Driver     	"s3virge"
    ChipSet	"virge"
    BusID      "PCI:0:11:0"
    VideoRam	4096

Section "Device"
    Identifier  "ATI Rage 128"
    Driver      "ati"
    BusID	"PCI:1:0:0"

Section "Screen"
    Identifier  "Screen 1"
    Device      "ATI Rage 128"
    Monitor     "My Monitor"
    DefaultDepth 16

    Subsection "Display"
        Depth       8
        Modes       "1280x1024" "1152x864" "1024x768"
        ViewPort    0 0
    Subsection "Display"
        Depth       16
        Modes       "1280x1024" "1152x864" "1024x768"
        ViewPort    0 0
    Subsection "Display"
        Depth       24
        Modes       "1280x1024" "1152x864" "1024x768"
	# Modes	    "800x600"
        ViewPort    0 0

Section "Screen"
	Identifier 	"Screen 2"
	Device		"S3 ViRGE"
	Monitor		"monitor2"
	DefaultDepth    16                                            	

	Subsection	"Display"
		Depth   16	
		Modes	"1280x1024"
		ViewPort	0 1200 


Section "ServerLayout"

    Identifier  "Simple Layout"
    #identifier must be present

    Screen "Screen 1"
    Screen "Screen 2" RightOf "Screen 1" 
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"

Basically... I simply set up two monitors and two video cards, and under the ServerLayout section i put them both in... notice the "RightOf" keyword... that tells X that my second video card/monitor is sitting to the right of the first one. for more info, like i said earlier, .

one final note, make sure that when you set up your cards you run them at the same color depth or else it won't work.
