Hi all,

A few months ago I configured my laptop Debian(Unstable) Dell D600 to automatically identify the second screen(VGA) and create a dual head using MergeFB.

Now you can see my xorg.conf configuration.

# xorg.conf (xorg X Window System server configuration file)## This file was generated by dexconf, the Debian X Configuration tool, using# values from the debconf database.## Edit this file with caution, and see the xorg.conf manual page.# (Type "man xorg.conf" at the shell prompt.)## This file is automatically updated on xserver-xorg package upgrades *only*# if it has not been modified since the last upgrade of the xserver-xorg# package.## If you have edited this file but would like it to be automatically updated# again, run the following command:#   sudo dpkg-reconfigure -phigh xserver-xorg
