Dual Head Monitor Setup with a Third Monitor
In IRC, I asked for a bit of help getting my third monitor to become part of my dual monitor display and many posed interested in learning how I accomplished it (if I got it working). Well I got it working, so here is my xorg.conf. I hope it helps.
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 1.0 (buildmeister@builder26) Fri Dec 15 10:40:27 PST 2006
# /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.

# sudo dpkg-reconfigure -phigh xserver-xorg
