    1. Is your touchpad working fine on Windows? Did you restarted your system after applying the commands in Ubuntu?

    2. You may try another trick for your Lenovo Ideapad 130.

      1. Install UKUU by using the below commands...

      sudo apt-add-repository -y ppa:teejee2008/ppa
      sudo apt-get update
      sudo apt-get install ukuu

      2. Start UKUU using GUI or by running "ukuu-gtk" in terminal.

      3. Choose the latest 4.19 kernel there and press install.

      4. Reboot the system.

      Hope it will help you.
