Step by step – Xinput Ubuntu 20.04 Tutorial

Getting Started

3. 3. Finding out Device Name

   So to Display Devices List
   Run:

   xinput list

   Select & Copy Device’s Name with Ctrl+x.

   

   Or simply take note of the Device’s ID.
   But if No Device Name but “xwayland” on GNOME Wayland then instead follow the linked Guide:

4. 4. Setting up Xinput Device Emulation

   Now to Enable Xinput Device Emulation on Ubuntu
   First, to list the available Properties run:

   xinput list-props "[DEVICENAME]"

   Or alternatively:

   xinput list-props [DEVICEID]

   So in this case for instance:

   xinput list-props "Kensington      Kensington Expert Mouse"

   Or else:

   xinput list-props 13

   

   Now in this practical Example I show you How to Set up a Trackball Scroll Emulation.
   Next to set up a Trackball Wheel Scroll, first enable it:

   xinput --set-prop "Kensington      Kensington Expert Mouse" "Evdev Wheel Emulation" 1

   So alternatively easier using the ID like:

   xinput --set-prop 13 "Evdev Wheel Emulation" 1

   And then set the Target Button:

   xinput --set-prop 13 "Evdev Wheel Emulation Button" 2

5. 5. Making Permanent Config

   Last, to make a Permanent Xinput Configuration File
   For a Single User using the nano editor, put your both Commands into:

   nano ~/.xsessionrc

   Ctrl+x to Save & Exit from nano Editor.
   So the setup should be consistent also after Reboot.
