Public bug reported:
Some settings that I have set in xorg.conf for the synaptics driver are
not being accepted or overwritten at some point during the start of X11.
My relevant parts from xorg.conf look like this:
Section "InputDevice"

EndSection
[...]
Section "ServerLayout"

EndSection
Which results in the following actual settings, as displayed by $synclient -l
Parameter settings:
LeftEdge = 160
RightEdge = 910
TopEdge = 150
BottomEdge = 640
FingerLow = 25
FingerHigh = 30
MaxTapTime = 87
MaxTapMove = 40
MaxDoubleTapTime = 60
SingleTapTimeout = 120
ClickTime = 20
FastTaps = 0
EmulateMidButtonTime = 75
VertScrollDelta = 12
HorizScrollDelta = 0
VertEdgeScroll = 1
HorizEdgeScroll = 0
VertTwoFingerScroll = 0
HorizTwoFingerScroll = 0
MinSpeed = 0.7
MaxSpeed = 1
AccelFactor = 0.05
EdgeMotionMinZ = 100
EdgeMotionMaxZ = 130
EdgeMotionMinSpeed = 100
EdgeMotionMaxSpeed = 230
EdgeMotionUseAlways = 0
UpDownScrolling = 1
LeftRightScrolling = 1
UpDownRepeat = 1
LeftRightRepeat = 1
ScrollButtonRepeat = 100
TouchpadOff = 0
GuestMouseOff = 0
LockedDrags = 0
RTCornerButton = 3
RBCornerButton = 2
LTCornerButton = 0
LBCornerButton = 0
TapButton1 = 1
TapButton2 = 2
TapButton3 = 3
CircularScrolling = 0
CircScrollDelta = 0.01
CircScrollTrigger = 0
CircularPad = 0
PalmDetect = 1
PalmMinWidth = 10
PalmMinZ = 200
CoastingSpeed = 0
PressureMotionMinZ = 30
PressureMotionMaxZ = 160
PressureMotionMinFactor = 1
PressureMotionMaxFactor = 1
Notice how FingerLow, FingerHigh, MaxTapTime, VertScrollDelta differ. They are
apparently set to some kind of default value.
