Ubuntu 9.04 1440x900 em SIS 671

[knife]

Boas, tenho um notebook do e-escolas insys com uma placa SIS671 (mirage 3) com o seguinte problema:

 - Quando instalo o ubuntu 9.04 a resoluçao maxima que posso escolher é de 800x600. Fiz uma pesquisa no forum com um amigo e instalei os drivers que estão neste topico: http://ubuntuforum-pt.org/index.php/topic,48807.0.html

Aconteceu que fiquei com o ecrã dividido em duas partes como mostra a foto:



Segue-se aqui o meu xorg:

# 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

# 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

comando terminal:  sudo gedit /etc/X11/xorg.conf

Procura isto :

Section "Device"
   Identifier   "Configured Video Device"

Depois editado fica assim

   Identifier   "Configured Video Device"
Driver "sis671"
