Right-click on Touchpad not working after update to 18.04 LTS

1. Install gnome-tweak-tool
2. open gnome-tweaks
3. go to Keyboard & Mouse
4. under Mouse Click Emulation, select Area.
5. Reboot.

Install gnome-tweak-tool by typing:

sudo apt-get install gnome-tweak-tool

Write gnome-tweaks in terminal and press Enter. This will open gnome-tweaks. Under Keyboard & Mouse option, go to Mouse Click Emulation. There are three options there. Choose Area.

In my case the issue was with my new lenovo ideapad laptop 330 for which right click will work when you press it with 2 fingers.

Might be case for someone else also so added as an answer.
