Having asked about touchpad not only once but twice. I have again come back to same topic :D. Basically I have a working two finger scrolling after adding the following line in /etc/profile after I enabled two finger scrolling in touchpad section of mouse.

xinput set-int-prop "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 32 40

But my touchpad sensitivity quite irritates me as it jumps around sometimes and also behaves scrolling as well as right click on single finger sometimes. Anyone can suggest me any tips to minimize this if not avoid ? Anyone know if I could use pinch zoom(Finally got the right term:)) as my touchpad says it supports such activity as well?

Thanks in advance.
