How to enable two finger scrolling in Ubuntu gnome 14.04 . The feature is seen enabled in dconf Editor, but it is not working. Also there is no option for scrolling in the mouse and touchpad settings.
When the command xinput; dmesg | grep pnp is typed in the terminal the following output is obtained.(I am copying the terminal output as I cant upload the screenshot image)
karthik@LenovoU41:~$ xinput; dmesg | grep pnp
