Hello
problem
first time i installed fedora(9) on my Dell laptop, i found that i couldn’t use the mouse touchpad as a left click
and that didn’t bother me, because it was useful somehow 
but when i tried to install ubuntu, i found that the toutchpad click is working very well
that doesn’t mean that the solution is to install ubuntu!!!
you must think and search for your problems’ solutions and never give up till you find them!!
Solution
few days later, i found the solution on cat-h4ck3rz forum and i wanted to share it
#vi /etc/X11/xorg.conf
add the following line in the ServerLayout Section
InputDevice "TouchPad" "CorePointer"
then add this new section:
Section "InputDevice"
Driver "synaptics"
Identifier "TouchPad"
Option "SendCoreEvents"
Option "Protocol" "auto-dev"
Option "SHMConfig" "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
EndSection
that’s it!
now restart your X window using (alt+ctrl+backspace)
and you’ll find your touchpad click is working!
good luck
