Problema com Video Intel 945GM - OpenGL - Ubuntu 8.10

[moises.ti]

Oi pessoal!

    Estou com um problema para rodar aplicativos que necessitem de aceleração de 3D. O Google Earth é um deles. Quando utilizo o aplicativo, parte da imagem que deveria estar sendo apresentada é mostrada com se fosse uma "tv fora de sintonia", ou seja, aquele "chuviscado". O Compiz esta funcionando corretamente. O DRI esta ativo no xorg.conf. Estou sem mais idéias para tentar corrigir esse problema. Se alguém conseguir me ajudar, apago o Vista!!
     Minha placa de Vídeo é a Intel X3100 ou 945GM e o drive intel esta instalado no Ubuntu 8.10. Segue o 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.
#
# 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
