How to enable Two finger scrolling on Lenovo Thinkpad T400 in Ubuntu 12.04 64 bit

Question

It is disabled (greyed out) in Mouse and Touchpad settings. Edge scrolling works though :) Tried many solutions available online but couldn't succeed.

My touchpad is

SynPS/2 Synaptics TouchPad

Please help.

Answer 1

it can be enabled also using commands:

xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Pressure" 4
xinput --set-prop --type=int --format=32 "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Width" 8
xinput --set-prop --type=int --format=8  "SynPS/2 Synaptics TouchPad" "Synaptics Two-Finger Scrolling" 1 0

Works on my T410...
