My laptop is: "Lenovo G580" and it comes with a very sensitive touchpad. Specially, when I place my hands comfortably to type, it "thinks" I'm touching the top-left corner. This becomes really annoying when I have to use both (the keyboard and touchpad), as it thinks I'm performing a 2 finger click (the mouse stop moving). I have disabled the 2 finger click, which defaults to right click, in order to prevent the right-click-menu randomly (imagine that!).

Using Xubuntu 12.10. These are my settings:

LeftEdge                = 2300
RightEdge               = 5000
TopEdge                 = 1652
BottomEdge              = 4658

MaxDoubleTapTime        = 180
SingleTapTimeout        = 180
ClickTime               = 100
FastTaps                = 0
EmulateMidButtonTime    = 75
EmulateTwoFingerMinZ    = 282
EmulateTwoFingerMinW    = 7
VertScrollDelta         = 110
HorizScrollDelta        = 110
VertEdgeScroll          = 0
HorizEdgeScroll         = 0
CornerCoasting          = 0
VertTwoFingerScroll     = 1
HorizTwoFingerScroll    = 0
MinSpeed                = 1

EdgeMotionMaxZ          = 160
EdgeMotionMinSpeed      = 1
EdgeMotionMaxSpeed      = 440
EdgeMotionUseAlways     = 0
TouchpadOff             = 0
LockedDrags             = 0
LockedDragTimeout       = 5000
RTCornerButton          = 0
RBCornerButton          = 0
LTCornerButton          = 0
LBCornerButton          = 0
TapButton1              = 1
TapButton2              = 0
TapButton3              = 2
ClickFinger1            = 1
ClickFinger2            = 1
ClickFinger3            = 0
CircularScrolling       = 0
CircScrollDelta         = 0.1
CircScrollTrigger       = 0
CircularPad             = 1
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         = 8
VertHysteresis          = 8
ClickPad                = 0

What I have tried:

1) The "CircularPad" option could solve my problem, but for some reason it doesn't work :(

2) Palm detection seems to fail as well... (currently disabled)

3) The "Block touchpad while typing" option resulted annoying as well, as I often use both input methods at the same time (like when you are searching for a file in a directory and type part of its name, and then clicking on the correct file). With that option, I have to wait about 3 secs in order to be able to use the touchpad, which I think is too much.

4) I could disable 2-finger scroll, but I use it a lot.

5) I thought that changing the Edges could be the easy way to go. I checked X and Y values in: "synclient -m 100" , and change the LeftEdge and RightEdge values as shown above. But even after setting them (using synclient LeftEdge=...) the cursor still moves below the LeftEdge and after the RightEdge, what am I doing wrong?

It seems that many options have no effect (like TapAndDragGesture), while changing others do (like setting 3 finger middle-click, etc.). Is that possible?

What other alternatives could I try to solve it? Thanks in advance!
