Configure external monitor to be --left-of laptop screen (nouveau)

Hi,

I have problem configuring external monitor to work like nvidia's 'twinView'.
Having no xorg.conf my external monitor is configured just to clone image displayed on latop screen. I can setup correct resolution in my DE (I'm using XFCE), but what confuses me is how to configure external monitor to work as separate screen (not to present cloned image).

This my my output from xrandr:

[kuba@t61:~]$ xrandr
Screen 0: minimum 320 x 200, current 3120 x 1050, maximum 8192 x 8192
LVDS-1 connected 1440x900+1680+0 (normal left inverted right x axis y axis) 304mm x 190mm
   1440x900      60.13*+  50.00  
   1152x864      59.96  
   1024x768      59.92  
   800x600       59.86  
   640x480       59.38  
   720x400       59.55  
   640x400       59.95  
   640x350       59.77  
VGA-1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm
   1680x1050     59.95*+
   1280x1024     75.02    60.02  
   1152x864      75.00  
   1024x768      75.08    60.00  
   800x600       75.00    60.32  
   640x480       75.00    60.00  
   720x400       70.08  
DVI-D-1 disconnected (normal left inverted right x axis y axis)

Following wiki instructions (http://nouveau.freedesktop.org/wiki/Randr12/) this commad helps me to setup what I want:

xrandr --output VGA-1 --left-of LVDS-1

and I want to persist such configuration.

I tried to configure it in  /etc/X11/xorg.conf (there was no such file)

[kuba@t61:~]$ cat /etc/X11/xorg.conf.bak 
# the right one
Section "Monitor"
          Identifier   "LVDS-1"
          Option "PreferredMode" "1440x900_60.13"
EndSection

# the left one
Section "Monitor"
          Identifier   "VGA-1"
          Option "PreferredMode" "1680x1050_59.95"
          Option "LeftOf" "LVDS-1"
EndSection

Section "Device"
    Identifier "nvidia card"
    Driver "nouveau"
    #Option  "Monitor-DVI-I-1" "NEC"
    #Option  "Monitor-DVI-I-2" "FUS"
EndSection

Section "Screen"
    Identifier "screen0"
   Monitor "VGA-1"
    DefaultDepth 24
      SubSection "Display"
       Depth      24
       #Virtual 2560 2048
      EndSubSection
    Device "nvidia card"
EndSection

Section "ServerLayout"
    Identifier "layout0"
    Screen "screen0"

But it seems like still there is something wrong as every time I run X I have cloned output on both screens.
Any ideas?

          Option "LeftOf" "LVDS-1"

Should that not be "left-of"?

I don't know. Is wiki wrong? (http://nouveau.freedesktop.org/wiki/Randr12/)

^ Ah, probably not then...
I was just comparing it with the xrandr command syntax
