Two finger scrolling stopped working suddenly

  • 772

I'm running Ubuntu 18.04 on a Thinkpad T480, and two finger scrolling wasn't working at seemingly random times, and now it doesn't work at all.

Could use some help troubleshooting.

    I have this same problem
    You can restart the touchpad by:
    sudo modprobe -r psmouse
    Then,
    sudo modprobe psmouse
    If you have this problem whenever you wake from suspend, then copy this script:

    #!/bin/sh

case $1/$2 in
  pre/*)
    echo "Going to $2..."
    # Place your pre suspend commands here, or `exit 0` if no pre suspend action required
    modprobe -r psmouse
    ;;
  post/*)
    echo "Waking up from $2..."
    # Place your post suspend (resume) commands here, or `exit 0` if no post suspend action required
    sleep 2
    modprobe psmouse
    ;;
esac

    Now, place it in the /usr/systemd/system-sleep folder, and name it whatever you want.
    Now, type sudo chmod +x "whatever you named your script"

  2. There may be an option in the settings. Check under the touch pad settings, or try reinstalling touchpad drivers.

  3. Closing the lid to suspend and waking the laptop back up fixed it for me.
