    Synaptics Touchpad - WhatPulse - editing with udev

    Note: The fix can be found on page 2 of this thread.

    Hello,

    I want to install the WhatPulse client on my laptop running Ubuntu 10.04. However, there seems to be an issue with the ability to grab clicks from the touchpad, as described at http://jmrk.whatpulse.org/. The solution described there is one for 9.10 (or earlier) and as such not relevant anymore since a HAL has been dropped in favor of udev rules.

    So, after some research I came across this thread and used
    Code:
    synclient GrabEventDevice=0
    to successfully change that setting. Successfully in the sense that doing
    Code:
    synclient -l
    shows the line "GrabEventDevice = 1".

    However, when clicking the buttons of my touchpad, the clicks still aren't registered by my touchpad. So I used the udev configuration in hopes of fixing it that way. Adding the file /etc/udev/rules.d/touchpad.rules with the following contents
    Code:
    ACTION!="add|change", GOTO="touchpad_end"
    KERNEL!="event*", GOTO="touchpad_end"
    ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="touchpad_end"
    ENV{x11_options.GrabEventDevice}="0"
    LABEL="touchpad_end"
    Then I rebooted in hopes of seeing the effect, but using
    Code:
    synclient -l
    doesn't even show GrabEventDevice as being set to 0. I'm not sure what I do wrong here, I don't really have any experience with udev. The part that troubles me most is that even setting the key-value from the command line doesn't seem to effect my ability to register clicks.

    you are not running Ubuntu 10.04. You are running Ubuntu 10.04 beta that is ment for testing. so maybe you will find more support in some testing forums.

    Have you tried:
    Code:
    ACTION!="add|change", GOTO="touchpad_end"
    KERNEL!="event*", GOTO="touchpad_end"
    ENV{ID_INPUT_TOUCHPAD}!="1", GOTO="touchpad_end"
    ENV{x11_options.SHMConfig}="on"
    ENV{x11_options.GrabEventDevice}="0"
    LABEL="touchpad_end"
    It has been a while since I have configured synaptics, but I think that you need to have SHMConfig turned on but I could be wrong.

    Re: Synaptic Touchpad - editing with udev

    Nop, still doesn't seem to do the trick.

    I went into /var/log/udev to see if things got triggered. It did, but I also noticed some other events that might be relevant (might as in: I really got no clue). So I edited the udev rule to

    Code:
    ACTION!="add|change", GOTO="touchpad_end"
    ENV{DEVPATH}!="/devices/platform/i8042/serio4/input/input7*", GOTO="touchpad_end"
    ENV{x11_options.SHMConfig}="on"
    ENV{x11_options.GrabEventDevice}="0"
    LABEL="touchpad_end"
    In hopes that would cover them all, which it did, going by /var/log/udev
    Code:
    UDEV  [1273146397.853934] add      /devices/platform/i8042/serio4/input/input7 (input)

    However, the WhatPulse program still doesn't seem to notice any clicks I make.

    It looks like it is missing:
    Code:
    ENV{x11_driver}="synaptics"

    Sadly enough, that also didn't do the trick
