Virtual scrolling with Alps trackpad on Dell Inspiron 1420n laptop


I'm having trouble configuring X to allow virtual scrolling using my trackpad. I know virutal scrolling (dragging along the right and bottom edges of the trackpad) works, because I previously had it working; however, I had to reinstall Fedora and I forgot to keep the settings, and now I can't get it working again.

The trackpad uses the synaptics driver, and X is recognising the trackpad correctly (I can see this from /var/log/Xorg.0.log), and the synclient program is able to adjust the settings in realtime.

Here's the section from xorg.conf:

Code:
Section "InputDevice"
        Identifier "Alps Touchpad"
        Driver "synaptics"
        Option "SendCoreEvents" "true"
        Option "Device" "/dev/input/mouse2"
        Option "Protocol" "alps"
        Option "Emulate3Buttons" "on"
        Option "SHMConfig" "true"

        Option "VertScrollDelta" "100"
        Option "MaxSpeed" "0.6"
        Option "AccelFactor" "0.2"
EndSection
And here's the output from synclient -l:

Code:
Parameter settings:
    LeftEdge             = 1900
    RightEdge            = 5400
    TopEdge              = 1900
    BottomEdge           = 4000
    FingerLow            = 53
    FingerHigh           = 58
    MaxTapTime           = 180
    MaxTapMove           = 220
    MaxDoubleTapTime     = 180
    SingleTapTimeout     = 180
    ClickTime            = 100
    FastTaps             = 0
    EmulateMidButtonTime = 75
    VertScrollDelta      = 50
    HorizScrollDelta     = 0
    VertEdgeScroll       = 1
    HorizEdgeScroll      = 1
    VertTwoFingerScroll  = 0
    HorizTwoFingerScroll = 0
    MinSpeed             = 0.09
    MaxSpeed             = 0.6
    AccelFactor          = 0.2
    EdgeMotionMinZ       = 30
    EdgeMotionMaxZ       = 160
    EdgeMotionMinSpeed   = 1
    EdgeMotionMaxSpeed   = 400
    EdgeMotionUseAlways  = 0
    UpDownScrolling      = 1
    LeftRightScrolling   = 1
    UpDownRepeat         = 1
    LeftRightRepeat      = 1
    ScrollButtonRepeat   = 100
    TouchpadOff          = 0
    GuestMouseOff        = 0
    LockedDrags          = 0
    RTCornerButton       = 2
    RBCornerButton       = 3
    LTCornerButton       = 0
    LBCornerButton       = 0
    TapButton1           = 1
    TapButton2           = 2
    TapButton3           = 3
    CircularScrolling    = 0
    CircScrollDelta      = 0.01
    CircScrollTrigger    = 3
    CircularPad          = 0
    PalmDetect           = 1
    PalmMinWidth         = 10
    PalmMinZ             = 200
    CoastingSpeed        = 0
    PressureMotionMinZ   = 30
    PressureMotionMaxZ   = 160
    PressureMotionMinFactor = 1
    PressureMotionMaxFactor = 1
I'm running Fedora 8 with the stock 2.6.24.4-64.fc8 Fedora kernel.

Can anyone suggest why virtual scrolling isn't working? From what I can see, it should be because UpDownScrolling and VertEdgeScrolling are both enabled.

Thanks in advance
David
