Estou com o mesmo problema!!!
já tentei vários tutoriais e nada!!!!
A configuração na resolução de tela no ubuntu 8.10. Ela nao ultrapassa 640x400 85hz. Ja tentei "ns" maneiras de configurar Xorg.conf, entretanto nada resolve.
Minha placa mãe é uma MSI P4M800 (VGA - VIA Technologies, Inc. KM400/KN400/P4M800 [S3 UniChrome).
Meu xorg.conf está assim:
# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuratio$
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf manual pag$
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package up$
# if it has not been modified since the last upgrade of the xse$
# package.
#
# Note that some configuration settings that could be done prev$# in this file, now are automatically configured by the server $
# here are ignored.
#
# If you have edited this file but would like it to be automati$
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
