For verification, steps I did were:
1. dmesg | grep elan, verify it says "elantech: assuming hardware version 4"
2. Launch Mouse and Touchpad settings, verify there is a Touchpad tab and it includes and has enabled a Two-finger scrolling option
3. In gnome-terminal, run 'dmesg' then verify two-finger scrolling scrolls the output
