X Config for dual head


I am trying to set up dual head. One is AGP (Geforce 2 GTS), and the other one is ATI Radeon 7500. I've been toying around with the XF86Config file, but I still couldn't get it to work. Here's the important sections of the file

Section "ServerLayout"
Identifier "Default Layout"
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "DevInputMice" "AlwaysCore"

EndSection

Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Dell P1110"
DisplaySize 400 300
HorizSync 30.0 - 121.0
VertRefresh 48.0 - 160.0
Option "dpms"
EndSection

Section "Monitor"
Identifier "Monitor1"
VendorName "Monitor Vendor"
ModelName "Dell P1110"
DisplaySize 400 300
HorizSync 30.0 - 121.0
VertRefresh 48.0 - 160.0
Option "dpms"
EndSection

Section "Device"
Identifier "Videocard0"
Driver "radeon"
VendorName "Videocard vendor"
BoardName "ATI Radeon 7500"
BusID "PCI:0:10:0"
Screen 0
EndSection

Section "Device"
Identifier "Videocard1"
Driver "nv"
VendorName "Videocard vendor"
BoardName "NVIDIA GeForce 2 GTS (generic)"
BusID "PCI:1:5:0"
Screen 1
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection

Section "Screen"
Identifier "Screen1"
Device "Videocard1"
Monitor "Monitor1"
DefaultDepth 24
SubSection "Display"
Depth 16
Modes "800x600" "640x480"
EndSubSection
SubSection "Display"

Modes "1280x1024" "1280x960" "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
EndSection

I got my BusID numbers by running scanpci. The error is something like this

nv (driver) could not find match on instance (PCI 1:5:0)
screen 1 deleted, no matching device

i hope someone out there could help me!

thanks!

lspci

thanks for the reply. hmmm i tried lspci and it gave the same BusID - PCI 1:5:0.

i was wondering if the way i'm describing my GeForce 2 card in the config file correct or not.... hmm...

In your device section for the GeForce, change Screen 1 to Screen 0

That option is used when you have a card that supports dualhead by itself.. also AGP buses are always on PCI:1:0:0.. try that as well.

You can also look in /var/log/XFree.x.log and see what the probe finds..
