    two finger scroll synaptic touchpad...

    i have an Acer 5920g notebook
    it has a synaptic touchpad and a lateral touch-sensitive multimedia bar that the system sees as a second touchpad
    i have configured the last one to work (with xinput and xbindkey). that's ok.
    I'm not able to make two fingers gesture works!
    in preference/mouse and touchpad/touchpad tab i cannot select it
    even if i activate TwoFingerScroll with synclient it doesn't work
    **all the previous system in the forum seem not work**
    any idea?

    ubuntu precise x64

    Re: two finger scroll synaptic touchpad...

    i have a dv6 hp pavilion ,and have the same problem,mine is also a synaptics touch pad,everything works except for the '2 finger scroll'.
    In the system settings ,on the touch-pad options the 2 finger scroll button is grayed out and hence I can't select it.
    I currently use the lateral edge scrolling for vertical scrolling.
    To make the 2 finger scroll work I have to add the following lines to the etc/x11/xorg.conf file

    Section "InputClass"
    Identifier "Default touchpad buttons"
    Driver "synaptics"
    MatchIsTouchpad "on"
    Option "LockedDrags" "1"
    Option "VertTwoFingerScroll" "1"
    Option "EmulateTwoFingerMinZ" "10"
    Option "EmulateTwoFingerMinW" "5"
    EndSection

    ------------------------------------------------------------------------------

    #!/bin/sh
    synclient VertTwoFingerScroll=1
    synclient HorizTwoFingerScroll=1
    synclient EmulateTwoFingerMinW=5
    synclient EmulateTwoFingerMinZ=10
    synclient VertEdgeScroll = 1
    synclient HorizEdgeScroll = 1

    and make this above script run at every boot by adding it to start up applications.

    No other method works,if someone can make the default settings work then it would be great.

    hope it helps

    I followed your instructions but it wasn't succesful.
    if i get synclient it responds:
    LeftEdge = 1752
    RightEdge = 5192
    TopEdge = 1620
    BottomEdge = 4236
    FingerLow = 25

    FingerPress = 256

    EmulateMidButtonTime = 75
    EmulateTwoFingerMinZ = 10
    EmulateTwoFingerMinW = 5

    VertEdgeScroll = 1
    HorizEdgeScroll = 1

    HorizTwoFingerScroll = 1

    AccelFactor = 0.0398089
    TrackstickSpeed = 40
    EdgeMotionMinZ = 30
    EdgeMotionMaxZ = 160
    EdgeMotionMinSpeed = 1
    EdgeMotionMaxSpeed = 401
    EdgeMotionUseAlways = 0
    UpDownScrolling = 1
    LeftRightScrolling = 1
    UpDownScrollRepeat = 1
    LeftRightScrollRepeat = 1
    ScrollButtonRepeat = 100
    TouchpadOff = 2
    LockedDrags = 1
    LockedDragTimeout = 5000
    RTCornerButton = 2
    RBCornerButton = 3
    LTCornerButton = 0
    LBCornerButton = 0
    TapButton1 = 1
    TapButton2 = 3
    TapButton3 = 0
    ClickFinger1 = 1
    ClickFinger2 = 1
    ClickFinger3 = 0
    CircularScrolling = 0
    CircScrollDelta = 0.1
    CircScrollTrigger = 0
    CircularPad = 0
    PalmDetect = 0
    PalmMinWidth = 10
    PalmMinZ = 200
    CoastingSpeed = 20
    CoastingFriction = 50
    PressureMotionMinZ = 30
    PressureMotionMaxZ = 160
    PressureMotionMinFactor = 1
    PressureMotionMaxFactor = 1
    ResolutionDetect = 1
    GrabEventDevice = 1
    TapAndDragGesture = 1
    AreaLeftEdge = 0
    AreaRightEdge = 0
    AreaTopEdge = 0
    AreaBottomEdge = 0
    HorizHysteresis = 25
    VertHysteresis = 25
    ClickPad = 0

    so i can check that the commands are recived, but there is no effect.
    (two fingers doesn't works, in the mouse properties is still greied).
