Multi touch for any,all synaptics touchpad
Multi-touch became trendy after iphone came up with it. We are seeing many new laptops with multi-touch. At hardware level, there is nothing special that you need, to make multi-touch work. You can also do two-finger scroll and two-finger tap to right/middle click. Also, three-finger tap, but, for me it is very hard to press three fingers at the same time(1 out of 10).
Create new file
gksudo gedit /etc/hal/fdi/policy/11-x11-synaptics.fdi
Paste the following code into the file and save it.
synaptics

Restart hal and enjoy multitouch touchpad.
sudo /etc/init.d/hal restart
Update: Diagnosing your touchpad for multi-finger-sensing-capability
Few people have problem with this not working, while it works for few others. This is posted in ubuntu forums
synclient -m 100
Fifth column in the output f is number of fingers on your touchpad. Put two or more fingers on your touchpad and watch the column. If you see it more than one, this should work for you.

But hal doesn't exist any more in ubuntu 10.04 and 10.10.
And someone advise to try with these command:
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 8 1 1
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 10
xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 32 8
I got response as follow:
-----------------------------------------------------------------------------------------------
peter@peter-K42Jc:~$ xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Two-Finger Scrolling" 8 1
unable to find device SynPS/2 Synaptics TouchPad
-----------------------------------------------------------------------------------------------
Then, I try this:
-----------------------------------------------------------------------------------------------
peter@peter-K42Jc:~$ xinput list
