Lubuntu 18.10 How to activate tap to click

Question

I'm using a fresh install 18.10 on my Samsung Serie 5 Ultra 530U3C A0L notebook.

I really enjoy the Linux experience so far and everything I need works out of the box for me. The only thing missing is tap to click. How can I activate it? I looked for an option in lxqt but couldnt find one. I googled a bit and found this: synclient tapbutton1=1 but typing this in the terminal did not help.

Answer 1

this works for me
https://wiki.archlinux.org/index.php/Libinput#Touchpad_configuration

create:

/etc/X11/xorg.conf.d/30-touchpad.conf  

content:

Section "InputClass"   
  Identifier "touchpad"  
  Driver "libinput"  
  MatchIsTouchpad "on"  
  Option "Tapping" "on"  
EndSection

and finally

reboot

EDIT 06/07/2022 works in Lubuntu 22.04 (presumably works from Lubuntu 20.04 onwards):

1. Open "Keyboard and Mouse Settings"
2. Scroll down to "Mouse and Touchpad"
3. Click on "Device:", select your touchpad (e.g., SynPS/2 Synaptics TouchPad)
4. Check "Tap to click"
5. Select "Apply"

Activating tap-to-click with xinput via command line

1. Find your device id (in my case 13 bellow ):

   # xinput list
   

   Look for:

   ↳ ETPS/2 Elantech Touchpad   id=13   [slave  pointer  (2)]
   

2. Find the "Tapping" desired option code (in my case 283 bellow):

   # xinput list-props 13
   

   Look for:

   libinput Tapping Enabled (283): 0
   

3. Activate it with "1" using:

   # xinput set-prop 13 283 1
   

4. List props once more to confirm:

   # xinput list-props 13
   

   Look for:

   libinput Tapping Enabled (283): 1

I don't know if that was already available in 18.10, but in 20.04 there is a setting for that (see Touchpad > Tap to Click):
