デュアルディスプレイ(Ubuntu)

デュアルディスプレイ posted by (C)cubicdaiya

会社でデュアルディスプレイな環境に慣れすぎてしまったので、自宅でもこの環境を構築することにしました。
ただ、Ubunttu*1だとxorg.confいじったりしないといけないので、Windowsみたいに設定は簡単ではないです。
なんか次期バージョンの7.10ではこのへんをGUIでできるようになるみたいですが。

自分のだとこんな感じ。

# /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 command:
#   sudo dpkg-reconfigure -phigh xserver-xorg
