Hello, 
 
The ugly thing people tell us is that in KDE NEON preferences, it does 
not appear as a touchopad and can not change anything. 
Many people tell us why it does not appear as a touchpad. 
 
The touchpad can work with evdev or with libinput. 
 
- To get touchpad hardware id: 
     hwinfo --mouse 
     *Previous command returns the line: 'Unique ID: AH6Q.bGO0sOimOM3' 
      and line 'Model:  "ImExPS/2 Generic Explorer Mouse"' 
         (model name used later for setting properties using 'xinput') 
 
- To get touchpad properties we can modify: 
     xinput --list-props "ImExPS/2 Generic Explorer Mouse" 
     *We can use model name (like previous line) or number id related 
with model name obtained when running command 'xinput': xinput 
--list-props 11 
 
- To modify values of properties 'libinput Accel Speed' and 'libinput 
Natural Scrolling Enabled': 
     xinput --set-prop "ImExPS/2 Generic Explorer Mouse" "libinput Accel 
Speed" 1 
     xinput --set-prop "ImExPS/2 Generic Explorer Mouse" "libinput 
Natural Scrolling Enabled" 1 
     *Like in previous step, we can use number id instead of model name. 
Propertie "libinput     Natural Scrolling Enabled" accepts values 0 or 
1. Propertie "libinput Accel Speed" accepts values between -1 and 1. 
 
Thanks for your support,
