sure..i am a complete newbie!

so excuse me if i posted something which is very obvious

went to this page which was suggested by the page stephen mentioned!

http://w1.894.telia.com/~u89404340/touchpad/files/

downloaded the latest version which is 0.12.1

then went thru these steps

extracted the .bz2 file by right clicking it and doing extract here...

went to the synaptics folder..and read thru the install file which had the instructions

It was a little misleading at times..but good enough

login as root in a shell

go to synaptics directory

Run "make install"


Then go to /etc/X11/ and open XF86config-4 file ( The install file wasnt clear on this!..did some searching to find how devices are listed and came to know abt this file)

Add/Replace in the InputDevice section for the touchpad the
following lines:

Section "InputDevice"
Driver "synaptics"
Identifier "Mouse[1]"
Option "Device" "/dev/psaux"
Option "Protocol" "auto-dev"
Option "LeftEdge" "1900"
Option "RightEdge" "5400"
Option "TopEdge" "1900"
Option "BottomEdge" "4000"
Option "FingerLow" "25"
Option "FingerHigh" "30"
Option "MaxTapTime" "180"
Option "MaxTapMove" "220"
Option "VertScrollDelta" "100"
Option "MinSpeed" "0.02"
Option "MaxSpeed" "0.18"
Option "AccelFactor" "0.0010"
Option "SHMConfig" "on"
# Option "Repeater" "/dev/ps2mouse"
EndSection


5. Add the "CorePointer" option to the InputDevice line at the ServerLayout section:

Section "ServerLayout"
...
InputDevice "Mouse[1]" "CorePointer"
...

Note! You can not have more than one core pointer, so if you want
to use an external mouse too, you have to set all mouse input
devices except one to "AlwaysCore" instead of "CorePointer".

Restart and it shud work hopefully...

However there are more instructions in the "install" file in the synaptics directory
