Xorg.conf problem... can't make the screen go 1024x768

[the8thstar]

Hello all,

I just installed gOS 3.0 (based on Ubuntu 8.04) on an old computer with an ATI Rage Pro card onboard.

The native resolution is 1024x768 bit I can't make it go beyond 800x600 for some reason.

Here is my xorg.conf :


# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
# sudo dpkg-reconfigure -phigh xserver-xorg

I replaced 800 with 1024 and 600 with 768 and now the screen is screwed up. Any great ideas?

1)make backup from your xorg.conf


2)change the "Modline" in your "Monitor" section following the guide on this page (http://www.x.org/wiki/FAQVideoModes) (this will set the settings for your monitor !!CAN BREAK YOUR MONITOR WHEN SET WRONG!!))

3) Remove the "Virtual" option in the "Screen" section (put a "#" in front of it) (not limited by a virtual screen of 640x480)
4)change "Modes" in the "Screen" section to 1024x768@60 (set resolution to 1024x768 )

This should do the trick.
