___ I have a laptop with 915g express chipset. I have enbled dual head using system-config-display Dual head is woking but second secreen is clone of first. even after enbaling xinerama and disabling clone it is still showing clone on sencond monitor. I have changed the resolution of second screen(800x600) by editing xorg.conf. But it still showing exact clone of first moniter (1024x768). I have fresh intalled fc5. ___

First of all the HW (video chip set) needs to support multi head display. There are desktop video cards that support multi (dual) head but I have not come across this feature on a laptop video display.
Are you perhaps referring to the laptop's LCD display and the VGA out at the back as "dual display?" If so, then you are wasting your time trying to configure multi head display. Typically on a laptop, you can toggle the video HW to display on (a) LCD only, (b) Both (LCD+VGA), (c) VGA only.

I too remember quite distinctly reading an article which showed how to setup two individual displays on a laptop even with the chip driver not supporting dual heads. It used xinerama. Right now I cannot find the link. Google around I am pretty sure theres a hack for this.

Xinerama is not the same as Multihead. With Multihead you have two (or more) displays that work independently. With Xinerama two (or more) displays work as one. http://www.tldp.org/HOWTO/Xinerama-HOWTO/intro.html

Read my post correctly. There is a method to make two displays work /independently/ without the chip driver supporting it.

I stand corrected w.r.t my post re dual head display on laptops. Some video chips sets in "newer" laptops do support dual head thru LCD and the VGA port *but* it is chip specific and not generic (from Google search for "dual+head+display+laptop+linux."
The OP needs to do his home work (research his video hardware) and figure if the X server for his chip set supports dual head. If so, then the following can help him http://www.granneman.com/techinfo/linux/installation/dualheadhowto.htm
