X11 Thinkpad Synaptics Touchpad Settings

52-thinkpad.conf

# 52-thinkpad.conf
# This is a X11 configuration file that tunes up the synaptics touchpad using the 
# synaptics libinput driver, I made this recopilating settings from different sources.
# Tested in elementaryOS 5.1

# Install HWE synaptics driver for Ubuntu 18.04.3+
# sudo apt install xserver-xorg-input-synaptics-hwe-18.04

# Install this file in:
# /usr/share/X11/xorg.conf.d/52-thinkpad.conf

# Set this to prevent overriding from Gnome Settings:
# gsettings set org.gnome.settings-daemon.plugins.mouse active false

# Reboot is required for synaptics driver to start and logout/login for the settings.
