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

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!
