ATI Mobility Radeon LY Dual display not working

Hello everybody,

Having a few problem setting the dual display up. I'm using the radeon driver on a ATI Mobility Radeon LY (16mb). I'm connecting a CRT through the vga connector but the display is not showing up on the CRT. I know my screens are working because the mouse will disappear off to the right. I've tried a few solutions in other posts but they are not working for me. Here is my xorg.conf:

Code:

Section "Module"
    Load        "dbe"  	# Double buffer extension
    SubSection  "extmod"
      Option    "omit xfree86-dga" 
    EndSubSection
    Load        "type1"
    Load        "freetype"
    Load       "glx"
EndSection



Section "ServerFlags"
    Option "Xinerama" "true"
EndSection



Section "Monitor"
    Identifier  	"Monitor[1]"
    HorizSync  		31.5 - 50.0
    VertRefresh 	40-90
EndSection

Section "Monitor"
    Identifier		"Monitor[2]"
    HorizSync  		31.5 - 50.0
    VertRefresh		40-90
EndSection



Section "Device"
    Identifier  "Radeon[1]"
    Driver      "radeon"
    VendorName	"ATI"
    BoardName	"ATI Radeon Mobility LY"
    BusID       "PCI:1:0:0"

    Option      "DPMS"
    #Option      "MonitorLayout" "LVDS, CRT"
    #Option     "UseDisplayDevice" "LVDS"
    #Option      "CRT2Position" "RightOf"
    #Option      "CRT2Hsync" "40-80"
    #Option      "CRT2VRefresh" "30-82"
    Screen       0
EndSection

Section "Device"
    Identifier      "Radeon[2]"
    Driver          "radeon"

    BoardName	    "ATI Radeon Mobility LY"

    VideoRam        16384
    Option          "DPMS"
    Screen          1
EndSection

    Identifier  "Screen[1]"

EndSection

    Subsection "Display"
        Depth       24
        Modes "1280x1024" "1024x768" "800x600" "640x480"
    EndSubsection
EndSection


Section "ServerLayout"

    Identifier "Layout[all]"

    Screen 0    "Screen[1]" 
    Screen 1    "Screen[2]" RightOf "Screen[1]"

    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"

EndSection

Any ideas why this isn't displaying on the CRT? I'm guessing I have to define Monitor[2] as CRT since Screen[2] is working? Ideally I would like my laptop display with a 1024x768 res, with the CRT on the LEFT at 1280x1024 but still have my laptop screen as my main.

Thanks in advance.
