Bom gente, eu irei posteriormente fazer um tutorialzinho mais completo sobre como configurei o linux para trabalhar em dual head, mas como estou meio sem tempo, por hora segue a configuração que eu fiz no /etc/X11/xorg.conf. Qualquer dúvida me adicionem no msn: geleiamocoto@hotmail.com
# /etc/X11/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 /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/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 commands:
#
# cp /etc/X11/xorg.conf /etc/X11/xorg.conf.custom
# sudo sh -c 'md5sum /etc/X11/xorg.conf >/var/lib/xfree86/xorg.conf.md5sum'
# sudo dpkg-reconfigure xserver-xorg
