Synaptics: configura tu trackpad

Brevísima entrada para recordar lo sencillo que es configurar nuestro trackpad gracias a synaptics.

Instalamos el driver:

$ aptitude install xserver-xorg-input-synaptics

Comprobamos la configuración actual de nuestro trackpad:

$ synclient -l

LeftEdge                = 127
    RightEdge               = 3054

    CircularPad             = 0
    PalmDetect              = 1
    PalmMinWidth            = 10

    PressureMotionMinZ      = 30
    PressureMotionMaxZ      = 160
    PressureMotionMinFactor = 1
    PressureMotionMaxFactor = 1
    GrabEventDevice         = 0
    TapAndDragGesture       = 1
    AreaLeftEdge            = 0
    AreaRightEdge           = 0
    AreaTopEdge             = 0
    AreaBottomEdge          = 0
    HorizHysteresis         = 19
    VertHysteresis          = 19
    ClickPad                = 1
    RightButtonAreaLeft     = 1590
    RightButtonAreaRight    = 0
    RightButtonAreaTop      = 1730
    RightButtonAreaBottom   = 0
    MiddleButtonAreaLeft    = 0
    MiddleButtonAreaRight   = 0
    MiddleButtonAreaTop     = 0
    MiddleButtonAreaBottom  = 0

Cada parámetro se puede ajustar de forma individual mediante el comando synclient:

$ synclient TapButton3=2

(Esta configuración activa el click con 3 dedos para copiar).

Para mantener nuestra configuración cuando reiniciemos las X:

$ vim 50-synaptics.conf

Section "InputClass"
Identifier "Touchpad" # required
MatchIsTouchpad "yes" # required
Driver "synaptics" # required
Option "MinSpeed" "1.0"
Option "MaxSpeed" "1.75"
Option "AccelFactor" "0.054"
Option "TapButton1" "1" # left click with 1 finger
Option "TapButton2" "3" # right click with 2 fingers
Option "TapButton3" "2" # copy with 3 fingers
Option "VertTwoFingerScroll" "1" # scroll with two fingers
Option "HorizTwoFingerScroll" "0" # horizontal scroll off
Option "VertEdgeScroll" "0"
Option "PalmDetect" "1"
EndSection

Y lo copiamos a /etc/X11/xorg.conf.d

Podéis encontrar más información en la wiki de Debian, la wiki de Arch o el man de synaptics.

También existe la opción de configurar el trackpad a través de LibinputTouchpad, una implementación más moderna que synaptics que además soporta Wayland.

Happy point&clicking!!
