Source: github
If SDDM is running on Xorg, and you use libinput, just add Option "Tapping" "on" to a xorg conf file in /etc//X11/xorg.conf.d/ You can use this:
sudo vim /etc/X11/xorg.conf.d/20-touchpad.conf
Paste the following:
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "on"
Option "NaturalScrolling" "on"
Option "MiddleEmulation" "on"
Option "DisableWhileTyping" "on"
