My touchpad speed is too slow (it takes me two full swipes to get the mouse from one side of the screen to the other). This might be because I'm on a 4K monitor. I have increased the touchpad speed to its maximum setting in the Ubuntu 18.04 Settings. I have also checked the speed setting in the terminal using xinput
, e.g.
xinput --list --short
Which returns 15 as the device ID of my touchpad. When I execute xinput --list-props 15
, the libinput Accel Speed
is 1. According to the libinput docs, this must be in the range [-1,1] and is thus at the maximum value. Is there a way to increase the mouse speed further?

List all properties in your mouse/touchpad using
xinput --list-props 11
(MY TOUCHPAD ID IS 11, yours will be different) and see the id of the propertyDevice Accel Constant Deceleration
. Now type the commandxinput --set-prop 11 268 0.3
(MY TOUCHPAD DECELERATION PROPERTY ID IS 268, yours will be different) to decrease your mouse/touchpad deceleration. Since it's pretty tedious to type these two commands everytime you Log in, put these two commands in the end of the /home/{your user name}/.bashrc file so that these get executed automatically whenever you Log in.This solution has a minor error though. With time, you'll notice that your mouse/touchpad ID will often switch between a couple of values. You may also have seen that. Instead of using the device ID you can use its name as shown in
--list-props
. You may then usexinput --set-prop "SYNA8005:00 06CB:CD8C Touchpad" 268 0.3
instead of using the ID.
