Unhappy Resolution Problem in Ubuntu 5.10


Good Evening!

I recently installed Ubuntu and I'm having some issues with my resolution. I cannot raise the resolution to a higher level, my only options in the screen resolution menu are for 640 x 480 at 60 hz. It looks like the ATI drivers are installed correctly (radeon 9600Pro) per the xorg.conf file. I have attached the contents for any help anyone can give me...I basically want to have a duel boot system, Linux for everything, and WinXP for games. Here is the file:

# /etc/X11/xorg.conf (xorg 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 /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/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.
#
# 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

A couple of things in the Device section should the driver not be either radeon or fireglx whatever they call it and in the Monitor section you may want to put in some proper refresh rates for the monitor not all report the correct settings an example from my file.

Code:
# NEC P1250 +
Section "Monitor"
       DisplaySize      384   288     # mm
       Identifier   "Monitor0"
       VendorName   "NEC"
       ModelName    "P1250 +"
       HorizSync    31-110 # DDC-probed
       VertRefresh  55-160 # DDC-probed
       Option       "DPMS"  "true"
       Option       "BackingStore" "On"
EndSection
So you may want to edit the xorg.conf and make some changes.

Ubuntu uses sudo to give you root access so try in a console window sudo export XAUTHORITY=/home/user_name/.Xauthority changing the user_name to your name then sudo gedit /etc/x11/xorg.conf hopefully gedit is installed and the export command works for sudo. Make certain that the refresh rate settings you are trying are for your monitor setting them too high may damage it.

From a terminal, enter:
sudo gedit /ect/X11/xorg.conf

open the "xorg.conf" file
Try with higher refresh rates like this:

Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 28-70
VertRefresh 43-90
EndSection


Save file and exit,
I can't remember if I had to reboot or not.
