Step-by-step – Trackball Scroll Kali 2019 Setup Guide

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.

4. 4. Setting up Xinput Device Emulation

   Now to Enable Xinput Device Emulation on Kali
   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

   

   But if the “Wheel Emulation” Property is Not Found then you have to configure Evdev in Xorg like:

   sudo cp /usr/share/X11/xorg.conf.d/10-evdev.conf /etc/X11/xorg.conf.d/

   And then Reboot with:

   sudo reboot

   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.
   The setup should be consistent also after rebooting.
