Ubuntu 8.10 Toshiba Satelite resolução de 1024x768

Apanhei para configurar a resolução:
http://www.vivaolinux.com.br/dica/Configurando-o-xorg.conf-no-Ubuntu
Está bem explicado no link acima,
para mastigar mais um pouco segue:
Abri o console
Aplicativos > Acessorios > Consola
Digitei na tela preta

sudo su
sua senha
gedit /etc/X11/xorg.conf

Irá abrir a conf, coloquei o texto seguindo o vivaolinux:

# 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.
#
# 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
