Disabling tap-click Sony Vaio Kubuntu 11.10

[fallenstar]

Hi,

Looking through, this has been approached before, but the older workarounds http://ubuntuforums.org/showthread.php?t=875016 just don't apply, as HAL doesn't appear to exist, at least in my /etc/ folder.

Running Kubuntu 11.10 32 bit on a new Sony Vaio E Series.

I have disabled tapclick in the gui, everything involved in the touchpad doing anything but moving the cursor, I have dechecked, and yet it continues to work...

Is there a script I can adjust and make it go away forever? I still need the touchpad itself though...

Sorry for being a pain, this is my 5th OS attempting to get the backlight turned down, now it's dimmed (finally!) and I can't type as the curser buggers off...

With xinput!

Note that your device name will probably be different from the "Alps PS/2 ALPS DualPoint TouchPad" that's used here -- likely something like "SynPS/2 Synaptics TouchPad". Your available options will probably vary too, both depending on your pad and on your version of xserver-xorg-input-synaptics.

From the man page of synaptics;

Synaptics Tap Action
       8 bit, up to MAX_TAP values (see synaptics.h), 0 disables an element. order: RT, RB, LT, LB, F1, F2, F3.

RT is right top corner, RB right bottom corner, LT left top corner, LB left bottom corner, F1 non-corner one finger tap, F2 non-corner two finger tap, F3 non-corner three finger tap.

So to disable all taps everywhere with any number of fingers;

$ xinput set-prop "AlpsPS/2 ALPS DualPoint TouchPad" "Synaptics Tap Action" 0 0 0 0 0 0 0

An example of an easy-to-maintain script with which you can set properties;

#!/bin/bash
# this script sets some touchpad settings
# see 'man synaptics' for information about properties

DEVICE="AlpsPS/2 ALPS DualPoint TouchPad"  # change to match your device name
DELAY=0.1


setprop() {
    # sets a property.
    # arg $1: property name, rest ($@) are property values

    local property="$1"
    # we've saved $1 in $property, so shift it away so only the values remain
    shift

    # print what we're doing
    echo "-- ${property}: "$@""
    xinput set-prop "$DEVICE" "$property" "$@"
    errlvl=$?

    # check if the xinput command output errors and if so, call err() to exit
    [ $errlvl -gt 0 ] && err $? "$property" "$@"

    # pausing a bit to let the driver do its thing
    # some time ago doing this too fast could muck stuff up royally
    sleep $DELAY
}


err() {
    # spouts an error and exits.
    # arg $1: errorlevel, arg $2: property name, rest ($@) are property values

    local errlvl=$1
    local property="$2"
    # shift away $1 and $2 so only the values remain
    shift 2

    echo # padding
    echo "ERROR: xinput threw errorlevel $errlvl when trying to set property \"$property\" with values: "$@""
    exit $errlvl   # end script
}


# ------ execution start

echo "Pad settings for ${DEVICE}:"
# list available properties with 'xinput list-props "$DEVICE"'

setprop "Synaptics Tap Action"  0  0  0  0  0  0  0
# 0 disables an element. order: RT RB LT LB F1 F2 F3.

setprop "Synaptics Edge Scrolling" 1 1 0
# 3 values, vertical, horizontal, corner.

setprop "Synaptics Coasting Speed" 15 15
# FLOAT, 2 values, speed, friction

#setprop "Synaptics PROPERTYNAME" value1 value2 value3 ...

This is more or less what I use, but I set some additional values (Move Speed, Noise Cancellation, etc) -- and I certainly don't disable taps. D:

Save it as executable in ~/.config/autostart/, or in ~/.kde/Autostart/, or wherever as long as it ends up being run upon X start.
