    Touchpad Tap Stopped working & Synaptiks crashing

    Hi,

    Having followed the instructions here to enable proprietary video drivers for my laptop, it appears that my touchpad tap function has stopped working under KDE. Any help to get it back working would be appreciated. Here are the details:

    Laptop: Acer Aspire 5920
    Kubuntu & Ubuntu 12.10
    Xorg Downgraded to 1.12 to allow use of legacy ATI drivers.

    Tapping works fine in Ubuntu; it just fails in KDE.

    Error output when running 'synaptiks' from console:
    Code:
    QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
    Output of xinput -list
    Code:

    "synclient | grep Tap" produces:

        MaxDoubleTapTime        = 180
        SingleTapTimeout        = 180
        TapButton1              = 0
        TapButton2              = 0
        TapButton3              = 0
        TapAndDragGesture       = 1
    Things I've tried:
    • Re-installed kde-config-touchpad


    I think I just need to enable tapping in Xorg, but not sure how to go about this.

    Also, should I file a bug report with KDE regarding Synaptiks crashing? If so, how to I go about getting them the right information?

    Thanks.

    Re: Touchpad Tap Stopped working & Synaptiks crashing

    Well, I've not been able to get synaptiks workings, so I'll probably try file a bug report with them.

    However, after some looking around I've managed to create a custom xorg.conf file in /etc and it contains:

    Code:
     Section "InputClass"
           Identifier "touchpad"
           Driver "synaptics"
           MatchIsTouchpad "on"
                  Option "TapButton1" "1"
     EndSection
    This enables TouchPad tapping across the board in X.

    For others investigating such things, then this page is helpful.
