I don't see the "Synaptics Finger" or similar properties. Any ideas on how to reduce the touchpad sensitivity on pressure? Which property may be the equivalent of "Synaptic Finger" in my case? I have already checked related posts but they all mention the "Synaptic Finger" prop.
My Mouse & Touchpad settings screen looks like this: enter image description here

  1. Here is a similar question. I don't know if it will help, as it is for KUbuntu, but it is essentially the same. kubuntu 18.04: My touchpad sensitivity is way to high, configuring the touchpad in system settings doesn't affect anything. It is also in the settings, and that does not seem to work right now. Here is another possibility: https://help.ubuntu.com/community/SynapticsTouchpad. I hope it helps.
