After last update (which upgraded plasma from 5 to 6), I missed touchpad settings in System Settings program and it says:
No touchpad found
But my touchpad is actually working!
Here is list of my inputs:
$ xinput list
Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ ETPS/2 Elantech Touchpad id=12 [slave pointer (2)]

Let me know if you need any further information.
I can change the settings of touchpd using synclient
without any problem. Also I enabled tapping for touchpad by creating following file and it worked successfully:
cat /etc/X11/xorg.conf.d/70-synaptics.conf ✔
Section "InputClass"
Identifier "touchpad"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "1"
Option "TapButton2" "3"
EndSection
I’m just wondering why System Settings could not detect my touchpad. Besides that, I prefer to change the settings of touchpad graphically.
