1 computer with 2 monitor

so I recently installed ubuntu hardy heron in my laptop (i.e HP Pavilion tx1000). well to tell the truth it was quite nice. Hardy did recognize all the hardware in my laptop. from sound, wireless, bluetooth. it was quite magnificent. I even can use my usb wireless dongle (i.e wireless billionton) and hardy recognized it by default.

well, actually I was a bit confused how activate my dual monitors so I followed the step in this tutorial

here is the screenshot of what my monitors will look like

to have this dual monitor support you must use nvidia graphic card and plug another monitor in your laptop and edit you xorg.conf file matching my own. after you edit your xorg.conf restart the X server by pressing ctrl+alt+backspace. here is my xorg.conf

jacobian@jacobian-HP:~$ sudo vim /etc/X11/xorg.conf

# xorg.conf (X.Org 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

using extended monitor is really useful when you want to do multi tasking task. as you can use two monitor at once.
