[solved] Using Two Graphic Cards

Hey!

I'm trying to set up a multi screen enviroment, but i seem unable to use both my graphic cards at once! Only one at the time sad.
When i try and configure my second screen in the xorg.conf (doesnt matter wich screen) I allways get the error

(EE) Screen 1 deleted because of no matching config section.

Then only my monitor and device configured as "Screen 0" lights up.

So well... ive been at this problem back and forward for a week now... Just hoping now that some nice soul could shed some light on this rather puzzling problem for me.

My xorg.conf

Section "Monitor"
    Identifier "lcdScreen"
    VertRefresh  56-75
    HorizSync    30-81
EndSection

Section "Device"
    Identifier "Ati1"
    Driver     "radeon"
    Option     "AGPMode" "8"
    Option     "EnablePageFlip" "on"
    Option     "ColorTiling"   "on"
    Screen 0
    BusID      "PCI:5:0:0"
EndSection

Section "Screen"
    Identifier "AtiScreen1"
    Monitor    "lcdScreen"
    Device     "Ati1"
    DefaultDepth 24
    SubSection "display"
        Modes "1680x1050"
        ViewPort 0 0
    EndSubsection
EndSection

Section "Monitor"
    Identifier "crtScreen"
    VertRefresh 50-160
    HorizSync  30-97
    Option   "dpms" "1"
EndSection

Section "Device"
    Identifier "nvidia1"
    Driver "nv"
    Screen 1
    Option "ConnectedMonitor" "CRT"
    BusID "PCI:2:0:0"
EndSection

Section "Screen"
    Identifier "nvidiaScreen1"
    Monitor "crtScreen"
    Device "nvidia1"
    DefaultDepth 24
    SubSection "display"
    Modes "1600x1200"
    EndSubsection
EndSection

Section "InputDevice"
    Identifier "WaveBoard"
    Driver "kbd"
    Option "XkbModel" "pc104"
    Option "XkbLayout" "se,se"
    Option "XkbVariant" "svorakA5,"
    Option "XkbOptions" "grp:caps_toggle"
EndSection

Section "ServerFlags"
    Option "AutoAddDevices" "False"
    Option "AutoEnableDevices" "False"
EndSection

Section "Module"
    Load "dbe"
    Load "dri"
    Load "drm"
EndSection

Section "ServerLayout"
    Identifier "MainLayout"
    screen 0 "AtiScreen1" 0 0
    screen 1 "nvidiaScreen1" RightOf "AtiScreen1"
    InputDevice "WaveBoard"
EndSection

And yeah... i Dont want anything "stretched" like you do with xinerama/xrandr. i just want the x to start on each screen so that if i drag a half a window over the edge on one screen it doesnt show up on the other screen.

Thanks in advance for any kind of tip etc.

EDIT
I've changed the name on the nvidia screen section so it matches the "crtScreen" monitor section

Re: [solved] Using Two Graphic Cards

there's at least one error in your xorg.conf. the nvidia-screen points to a nonexisting monitor.
not sure if thats the real problem though - never used 2 graphic cards or multiple x-servers.

Thanks, i've been using a couple of names before a  settled down with crtScreen. But it's something else, after the fix the same error still occurs with the same results sad

Re: [solved] Using Two Graphic Cards

Heya! It worked! I just had to start a new session of my window manager on my other screen, ie "DISPLAY=:0.1 xmonad" But since then ive changed to awesome that supports zaphod mode natively, so i don't have to start the window manager on both screens. All this time...It wasn't the drivers nor hardware, it was the window manager!

*happy*
