HP2133上のUbuntu8.10の画面解像度を変更する

Hp2133にUbutnu8.10をインストールしたはいいものの、Xの設定がイマイチだったので、ここを参考にして、変更した。

まず、xorg.confを編集

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by reidy90, by copying correct settings from
# the xorg.conf that was provided with the SUSE hp 2133.
#
# 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.
#
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
#
# 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

それで、画面解像度を1280x768へ変更

さらにViaのサイトからドライバをダウンロード
展開したディレクトリの中から「via.ko」ファイルを/usr/lib/xorg/modules/driversへコピー
xorg.ocnfの "Section Device" 中"Driver" を "vesa"から"via"へ変更

これでバッチリ使えるようになりました。
