Enabling Tap to click function in Manjaro via the command line

In case you have Manjaro installed and your touchpad does not have the Tap-to-click ability, then the following suits you if you would wish to enable it via the command line. Before that, lets have a moment to enjoy some food for thought..

“Be content with what you have;
rejoice in the way things are.
When you realize there is nothing lacking,
the whole world belongs to you.”
— Lao Tzu

Enabling Tap-to-click function

 # xinput set-prop [device number] [option number] [setting]

To get the value of [device number], enter the following on the terminal:

sudo xinput list

You will get something that resembles the following:

Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ SynPS/2 Synaptics TouchPad id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ HP Webcam-101: HP Webcam-101 id=9 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)]
↳ HP WMI hotkeys id=12 [slave keyboard (3)]

Looking carefully, you will see something related to Synaptics from the output. Mine is "SynPS/2 Synaptics TouchPad." It has an id of 11 as it can be clearly seen. This is the [device number] value.

To get the value of [option number] of the device, do:

xinput list-props 11

The following will be the output:

Device 'SynPS/2 Synaptics TouchPad':
Device Enabled (142): 1
Coordinate Transformation Matrix (144): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

Device Node (266): "/dev/input/event5"
Device Product ID (267): 2, 7
libinput Drag Lock Buttons (297):
libinput Horizontal Scroll Enabled (298): 1

Look into the output and find “Tapping enabled” Option. From the output above we have "libinput Tapping Enabled (278): 0."
From that, we get the value of [option number] and value which are 278 and 0 respectively. The 0 is a binary value which means that it is disabled. Another way of checking whether the Tapping option is disabled or enabled, do enter the following on your terminal:

sudo libinput list-devices

You will get a long list of output and for the sake of the article, I have extracted the part related to the Touchpad

----

----

From the output, you can see that Tap-to-click is disabled.

Back to enabling the Tap-to-click functionality, we now have all of the variabled we need to enable it.
Do the following to enable Tap-to-click

# xinput set-prop 11 278 1

Where,
11 is the device number
278 is the device option number and
1 is the binary “True” to enable Tap-to-click

Looking back to see if the functionality is enabled, enter the following on your terminal as previously done:

 # xinput list-props 11

The output will look like the following:

Device 'SynPS/2 Synaptics TouchPad':
Device Enabled (142): 1
Coordinate Transformation Matrix (144): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
