hii frnds,
I have switched to ubuntu two weeks ago. I have installed ubuntu 8.10 dual boot with XP. My NVIDIA chipset is Geforce 6100 nforce 430.I have installed NVIDIA driver version 180.11 which was recommended. When i checked NVIDIA X SERVER setting it supported GeForce 6150SE nForce 430. My screen resolution changed to 1024x768 but required is 1280x1024. I have tried to change the screen resolution but there is no option of 1280x1024.
I have searched a post which explains the technique to change screen resolution but was posted in Mar 2006 .Here is the link
http://ubuntuforums.org/showthread.php?t=145553
I have also searched a blog post which has method of changing screen resolution.Here is the link
http://www.ubuntugeek.com/common-problems-and-solutions-for-nvidia-restricted-drivers-after-ubuntu-810-intrepid-ibex-upgrade.html
Now i m a bit confused about how to change the resolution manually since this is my 4th installation due to some errors.I need a step by step method so that i make no mistakes and dont crash my system.
Also my monitor is LCD but NVIDIA X SERVER setting displays CRT. Plz help me...
Thankx in advance....

Hi and welcome, you have tried nvidia-settings with
gksu nvidia-settings and the resolution 1280x1024 is not available?

yes i have tried that too.There is no option of 1280x1024 in X SERVER Display configuration. I want to change it manually now by editing the xorg.config but dont have step by step procedure to do so

This Link (https://wiki.ubuntu.com/X/Config/Resolution) maybe of some help.

this is how my xorg.config file looks like

# 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

I would suggest backing up your xorg first
To copy Xorg

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf-backup
To restore backup

sudo cp /etc/X11/xorg.conf.backup /etc/X11/xorg.conf
To edit your xorg you can use this command
sudo gedit /etc/X11/xorg.conf
