Problem with mouse and Keyboard when in X Window
 

Almost all my mouse's click on windows ( Button, Edit Box, etc ) doesn't get any effect at all, but I still can see the mouse cursor move arround when I move my mouse.

And sometimes my keyboard too. when the two input device doesn't get any reaction from the windows. it's give me no other choice except press reset button or power button.

someone knows what's the problem with my computer ?
(I am new in linux ).
using Gnome for Desktop manager.

Spec :
Pentium 4 2.8Ghz
Memory 256
and alot free space in root partition and swap partition.
using FC4
Graphics Card : NVIDIA 4000MX
Mouse : Genius PS2.

if noone else is gonna jump in here before it's too late, try this "brute force" method:
ensure you have written down all the correct hardware info for your box and peripherals.
from the terminal, as root:

#: xorgconfig

follow the on=screen prompts, and enter each as appropriate. take it slow, and be patient. one screw-up and you may have to redo the whole series of steps. no big disaster, but you'll see how irritating it can be if you do...
when you're done, log out, log back in/restart X, and havalottafun!
oh: if you have a wheel, edit /etc/X11/xorg.conf where the "Input Device" is, and include:

Option "ZAxisMapping" "4 5"

{note: one space between the 4 and 5)

hope this helps.
