Ubuntu 18.04 enable tap to click on touchpad
Recently I installed Ubuntu 18.04 and I got the problem with the touchpad where when I tap on it, it wasn’t detected as a click. There are so many fixes online but there is only one that worked for my machine (Dell 7559 with i7 and nvidia video card).
Just install the following dependency:
sudo apt-install xserver-xorg-input-synaptics-hwe-18.04
And everything seems to magically work.
