You should copy and paste the below mentioned code in the xorg.conf file.

Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "macintosh"
Option "XkbLayout" "fr"
Option "XkbVariant" "latin9"
Option "XkbOptions" "lv3:rwin_switch"
endSection

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
EndSection

Section "Device"
Identifier "Configured Video Device"
#Option "UseFBDev" "true"
Option "CCEusecTimeout" "100000"
EndSection

Section "Monitor"
Identifier "Configured Monitor"
HorizSync 43-62
VertRefresh 74-118 
# ModeLine "1024x768" 78.75 1024 1044 1140 1328 768 781 784 820 +hsync +vsync
ModeLine "800x600" 62.40 800 821 901 1040 600 609 612 644 +hsync +vsync
Modeline "640x480" 49.90 640 657 721 832 480 481 484 514 +hsync +vsync
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
DefaultDepth 24
Subsection "Display"
Modes "1024x768" "800x600" "640x480"
EndSubsection
EndSection

Section "Module"
Disable "dri"
EndSection

Once you have edited the file you should update the same by using below mentioned command.

sudo dpkg-reconfigure -phigh xserver-xorg

Before you go an apply above mentioned settings and went into synaptic package manager in order to install drivers for ATI Rage 128. In order to check the same you have to go for System and click on Administration and click on Synpatic Package Manager and enter ATI into quick search and there will be 18 checkboxes in the below mentioned manner.

As far as I know ubuntu 9.10 is not having /etc/X11/xorg.conf file. If you wanted the same then you will require to create the same by your own.
You can run the below mentioned command to create that particular file.

sudo nano /etc/X11/xorg.conf
