I have an HP laptop on which I installed Kubuntu 19.10 (Plasmashell 5.16.5).
I can use the touchpad just fine to move the cursor and click using the touchpad's buttons. However, I cannot click by double-tapping as I would using Windows.
Is there any particular software I need to install for this to work?
To fix this, I had to go into System Settings, then select Input Devices from the left, and finally Touchpad. The Tap-to-click option was what I needed to enable.
