Hi,

I have a sony vpc-z21 with a dockingstation. Two external display are connected
with the dockingstation and there is gnome-shell running. On the internal
display i have only a gnome-terminal running.


My xorg.conf is

Section "Monitor"
  Identifier   "LeftMonitor"
EndSection

Section "Monitor"
  Identifier   "RightMonitor"
EndSection

Section "Device"
  Identifier "radeon"
  Driver "radeon"
  BusID "PCI:22:00:0"
  Option "AccelMethod" "EXA"
  Option "AccelDFS"    "True"
EndSection

Section "Device"
  Identifier "intel"
  Driver "intel"
  BusID "PCI:00:02:0"
EndSection

Section "Screen"
  Identifier "LeftScreen"
  Device "radeon"
  Monitor "LeftMonitor"
EndSection

Section "Screen"
  Identifier "RightScreen"
  Device "intel"
  Monitor "RightMonitor"
EndSection

Section "ServerLayout"
  Identifier     "My X Server"
#  Option      "Xinerama" "on"
#  Option      "Clone" "off"
  Screen      0  "LeftScreen" 0 0
  Screen      1  "RightScreen" RightOf "LeftScreen"
EndSection

-------------------------------
But is not possible to move windows from the external monitors to the internal
display. You have to set the DISPLAY variable for the internal display.
For example i have a gnome-terminal on the internal display running:
DISPLAY=:0.1 gnome-terminal  -e "bash -c \"tail -f /var/log/Xorg.0.log
/var/log/kern.log ~/.xsession-errors;exec bash \"" &
