kde and xinerama

[Thomas Lemaire <thomas.lemaire@laas.fr>]

Dear list,

I am trying to use my debian/linux laptop with an external monitor to have an 
enlarge desktop. I am using kde3.4 and xorg package given on this list. I 
configured xorg with two devices, two screens, and a layout putting the two 
screen side to side. But I can't get kde on both screen...

First of all, is kde compilled in debian with the -xinerama option ? Is there 
a tool in kde to configure on the fly the layout of the xorg screens ?
If any body has such a working setup, could he send me its configuratios 
files ?

here are relevant parts taken from my xorg.conf
