This is /etc/X11/xorg.conf configuration files. If you need more information, please let me know.

Thanks for your help.

Your help is greatly appreciated by me and others.

Your xorg.conf misses two sections, one for mouse and one for monitor.
I can't say exactly what's right for you, here are my two sections as an example:

Section "Monitor"
Identifier "Monitor"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
# HorizSync 40-60
# VertRefresh 60-90
Option "DPMS" "true"
EndSection
Section "InputDevice"
Identifier "Mouse"
Driver "mouse"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPs2"
Option "Emulate3Buttons" "yes"
EndSection

Then add two lines, one for mouse to to the ServerLayout section:

Section "ServerLayout"
Identifier "Single head Configuration"
Screen "Screen0" 0 0
InputDevice "Keyboard0" "Corekeyboard"
InputDevice "Mouse" "Corepointer"
EndSection

another for Section "Screen":

Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor"
Depth 24
SubSection "Display"
viewport 0 0
Depth 24
Modes "800x600" "640x480"
EndSubsection
EndSection

The HorizSync and VertRefresh are not absolutely needed, be somewhat careful.

I don't really understand why you didn't get a correct config, it is normally done by the system?

Is it i have to add two section exactly same as you even though my hardware is not same as you.

My monitor is samsung syncmaster 153v and my mouse is optical mouse.

Perhaps, i install the fedora core 6 with acpi=off. I just guess. I also don't know.

Thanks for your help.

My understanding is that if you rename the xorg.conf file, then x will do a probe for you and create another. Dont delete your xorg.conf but rename it and reboot X.

ctl-alt-backspace should reboot X.

My question: Is it have to add two section exactly same as you even though i have different hardware ?

My monitor is samsung syncmaster 153v and mouse is optical mouse connect via usb ports.

Thanks for your help.

Plese double confirm with me.

You could try entering those 2 sections - mouse is very often the same device ("/dev/input/mice"), if it doesn't work for you you'll have to find out wwhere it is:
# find /dev -name '*mice*' -print
As for monitor, there's nothing specific in my section.
Just give it a try, it can't damage anyhing.

Your help is greatly appreciated by me. I will have a try.

I did not add the section but after i changed the hardwre which is my mouse and keyboard and the problem is solved. By the way, my mouse moded is ps/2 samsung-Smop5000wx-bk and keyboard is samsung-Ak3000SP-BK. This is a combo -lite and the model is k31c.
