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

  • Have you configured touchpad sensitivity in your settings? – Logan Mar 09 '20 at 14:58
  • No, from the settings the only configurable property seems to be the "Touchpad Speed". I also installed Gnome Tweaks but didn't find any options for the pressure sensitivity. My problem is the touchpad is too sensitive on pressure. – lainatnavi Mar 09 '20 at 15:09
  • That is a bit odd. I will do some research, and I will probably get back to you soon. – Logan Mar 09 '20 at 15:33
  • Here is a similar question. I don't know if it will help, as it is for KUbuntu, but it is essentially the same. https://askubuntu.com/questions/1029999/kubuntu-18-04-my-touchpad-sensitivity-is-way-to-high-configuring-the-touchpad. It is also in the settings, and that does not seem to work right now. I will post these as an answer. – Logan Mar 09 '20 at 15:37
  • Here is another possibility: https://help.ubuntu.com/community/SynapticsTouchpad. I hope it helps. – Logan Mar 09 '20 at 15:38
  • I tried xinput --set-prop 12 "Synaptics Finger" 50 80 257 even if the prop isn't shown in in list output but as expected didn't work. Got error property 'Synaptics Finger' doesn't exist, you need to specify its type and format – lainatnavi Mar 09 '20 at 17:30
  • Are you sure you installed the touchpad drivers for your touchpad? Sometimes, the Ubuntu drivers are not ideal... – Stefi Mar 12 '20 at 18:49

    @NegoescutzStefilutz after the installation the touchpad was working so I chose not to install third party drivers. During the installation process I had an internet connection and I chose "Automatically download third-party drivers". – lainatnavi Mar 12 '20 at 18:56

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.
