As of Ubuntu 17.10 I can no longer configure my touchpad with synclient. The palm detection feature of libinput has an extremely high false positive rate for me and I simply want to turn it off. Thank you for your help.


Touchpad settings in Ubuntu 17.10

You can turn off or modify the touchpad according to these screenshots.

  1. At the top right corner, select the tool symbol to get the Settings window
  2. Select Devices

    enter image description here

  3. Select Mouse & Touchpad settings

    • You can turn off the touchpad completely with the switch at the arrow, or

    • you can modify the other settings in order to get settings that work better than the default settings.

  • sudodus thanks for the reply, but I think you misunderstood my problem. I'm trying to disable the palm detection feature not disable the touchpad. – user757047 Nov 7 '17 at 14:30
  • I am not sure that there is an easy way to disable the palm detection feature (I don't know how to do it). But you can disable the touchpad as a last resort if nothing else works (in Wayland). There may be more possibilities in Xorg (x11). Have you tried that? (You can switch between Wayland and Xorg via the cog wheel symbol in the log in screen). – sudodus Nov 7 '17 at 14:51
  • @user757047, An alternative is to install an Ubuntu community flavour, Kubuntu, Lubuntu ... Xubuntu). None of them use Wayland. At least Lubuntu (and I think most of them) still works with synclient, so I think you can do what you have done before. But try live (booted from USB or DVD) before you decide to install one of the community flavours. – sudodus Nov 7 '17 at 15:09

    Also note that the Touchpad section of Settings does not always exist. On my Dell notebook, running 17.10, I have "General" and "Mouse", with nothing beneath that. – CommonsWare Apr 1 '18 at 11:00
