Just purchased a new Acer i5 laptop and found its Elantech touchpad not working properly inside Ubuntu. Worked like a charm in Windows though which eliminated any issue with the hardware. On digging more I found that the issue is with the options of ubuntu on how it configures it. To get it working follow the steps below

    cd /etc/modprobe.d/

    sudo gedit options.conf 

In the text editor, type: options psmouse proto=imps

Save the file and close it.

    sudo modprobe -r psmouse 

    sudo modprobe psmouse
