Decrease libinput Sensitivity

You can simply change the touchpad speed or how fast the cursor moves from the settings but you can't change the sensitivity of gestures and two finger navigation. To do this you need to reduce the sensitivity density

First get the touchpad size

libinput list-devices | grep Size

Then measure the touchpad and generate a custom config/snippet. The size here should be a division of the size returned from the above command.

sudo libinput measure touchpad-size 20x45

Now copy the snippet between the equal marks and paste it in the following file.

sudo nano /etc/udev/hwdb.d/61-evdev-local.hwdb

Now update hwdb

sudo systemd-hwdb update
sudo udevadm trigger /dev/input/event*

Finally reboot to view changes

reboot
