Hi Matthias,

Instead of modifying the X config file that came from the package or
adding your own custom xorg config files, you can use `xinput` to
modify these properties while X is running and, once you're happy,
automate that for startup in your ~/.xinitrc (I do this with all my
customizations, so that all configuration stays in my home directory).

You can list available devices using xinput, example:

$ xinput
⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ System mouse                              id=6    [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=9    [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                     id=10   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ System keyboard multiplexer               id=7    [slave  keyboard (3)]
    ↳ AT keyboard                               id=8    [slave  keyboard (3)]

In my case, the device is"SynPS/2 Synaptics TouchPad".

Using this, I can the drill into available properties:

$ xinput list-props "SynPS/2 Synaptics TouchPad"
Device 'SynPS/2 Synaptics TouchPad':
        Device Enabled (138):   1
        Coordinate Transformation Matrix (139): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
        libinput Tapping Enabled (293): 0

        libinput Scroll Method Enabled Default (265):   1, 0, 0
        libinput Click Methods Available (303): 1, 1
        libinput Click Method Enabled (304):    1, 0
        libinput Click Method Enabled Default (305):    1, 0
        libinput Middle Emulation Enabled (268):        1
        libinput Middle Emulation Enabled Default (269):        0
        libinput Accel Speed (270):     0.000000
        libinput Accel Speed Default (271):     0.000000
        libinput Left Handed Enabled (275):     0
        libinput Left Handed Enabled Default (276):     0
        libinput Send Events Modes Available (277):     1, 1
        libinput Send Events Mode Enabled (278):        0, 0
        libinput Send Events Mode Enabled Default (279):        0, 0
        Device Node (280):      "/dev/input/event3"
        Device Product ID (281):        2, 7
        libinput Drag Lock Buttons (282):       <no items>
        libinput Horizontal Scroll Enabled (283):       1

On my touchpad, using the command

$ xinput set-prop "SynPS/2 Synaptics TouchPad" "libinput Tapping Enabled" 1

enables tapping on my touchpad.

To make this change permanent, I then add the following lines to
my ~/.xinitrc file (obviously before starting the window manager,
probably nearby potentially existing calls to configure keymap with
setxkbmap):

  device="SynPS/2 Synaptics TouchPad"
  xinput set-prop "$device" "libinput Tapping Enabled" 1
  # for those who like "natural" scrolling:
  xinput set-prop "$device" "libinput Natural Scrolling Enabled" 1
  # etc.

You'll need to replace "SynPS/2 Synaptics TouchPad" with the
correct device name you determined using xinput above ("Cyapa
something").

Cheers,
Michael
