Enable tap to click with touch pad #195

Closed shenron closed 7 years ago

shenron commented 7 years ago

Hello,

Is it possible to have a click with a simple tap with the touch pad ?

Thank you very much.

This would be configured by your DE or via X.org. I have this enabled, for example.

In case you're not running a DE or your DE does not have a way to enable tapping (e.g. i3) an alternative consists of using xinput (this assumes you're using Xorg and not Wayland).

Retrieve the id of the touchpad with:

~ xinput list --id-only "Atmel maXTouch Touchpad"
9
xinput list-props 9
Device 'Atmel maXTouch Touchpad':
        Device Enabled (138):   1
        Coordinate Transformation Matrix (140): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000

        libinput Left Handed Enabled (285):     0
        libinput Left Handed Enabled Default (286):     0

        libinput Click Method Enabled (291):    0, 1
        libinput Click Method Enabled Default (292):    0, 1
        libinput Middle Emulation Enabled (293):        0
        libinput Middle Emulation Enabled Default (294):        0
        libinput Disable While Typing Enabled (295):    1
        libinput Disable While Typing Enabled Default (296):    1
        Device Node (261):      "/dev/input/event11"
        Device Product ID (262):        0, 0
        libinput Drag Lock Buttons (297):       <no items>
        libinput Horizontal Scroll Enabled (298):       1

In this example you'd enable tapping with:

xinput set-prop 9 273 1

A few things to note:

  1. The id for the touchpad it often but not always 9 (sometimes it's 13).
  2. This needs to be done on every reboot.

Hello,

Thank you for your help. In fact I use i3wm, so I use directly a configuration for Xorg.

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

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