When I updated to F9 I had some probs with my ati dual head card. My
conf file is:

Section "ServerLayout"
	Identifier     "ATI dual head configuration"
	Screen      0  "Default Screen" 0 0
	InputDevice    "Mouse0" "CorePointer"
	InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

... (modules, keyboard, etc)

Section "Device"

	Identifier	"ATI Radeon"
	Driver		"radeon"
	VendorName	"ATI corp."
	BoardName	"ATI Technologies Inc RV350 AP [Radeon 9600]"

EndSection

Section "Monitor"

	Identifier   "Panel-1"
	VendorName   "Monitor Vendor"
	ModelName    "NEC MultiSync LCD1700NX (Digital)"
	# Comment all HorizSync and VertSync values to use DDC:

EndSection

Section "Monitor"

	Identifier   "Panel-0"
	VendorName   "Monitor Vendor"
	ModelName    "NEC MultiSync LCD1700NX (Digital)"
	# Comment all HorizSync and VertSync values to use DDC:

	# VertRefresh  56.0 - 75.0
	Option	    "dpms"
	Option	"RightOf" "Panel-1"

EndSection

Section "Screen"
	Identifier "Default Screen"
	Device     "ATI Radeon"
	Monitor    "Panel-1"
	DefaultDepth     24

	SubSection "Display"
		Viewport   0 0
		Depth     24
		# big virtual screen to place the monitors
		Virtual   2560 1024
#		Modes    "1280x1024" "1024x768" "800x600" "640x480"
	EndSubSection

EndSection


Especially important is the "Virtual" option in section "Screen".

You may check for a ~/.gnome2/monitors.xml file and remove / rename it
and check. See https://bugzilla.redhat.com/show_bug.cgi?id=457673
