Optimizing behaviour of Synaptics Clickpad on Sony Vaio Z13

[Markus Ellinger]

Hi everyone,

I am using Linux Mint Nadia which ships with X.Org 1.13.0 on a Sony Vaio 
Z13. I experience two problems with the Synaptics driver which do not 
occur on the Windows 7 Professional installation on the same machine:

1. Moving the mouse pointer using the touchpad works fine, however, 
everytime when I release the finger from the touchpad, the mouse pointer 
"jumps" a little bit from its reached position. I guess this is because 
I do not release the finger steady enough and thus releasing the finger 
triggers some additional mouse pointer movement. This really is annoying 
because e.g. when I hover on a button, then release the finger to tap 
the button, often the mouse pointer jumps away from the button and the 
tap clicks the wrong button. Is there any way to tell the Synaptics 
driver in X.org to ignore movements when the finger is released? The 
Synaptics Windows driver does not have this problem, here when I release 
the finger, the mouse pointer never jumps. I already tried to play with 
some synclient options but to no avail.

2. The Sony Vaio Z13 has "ClickPad" buttons. They do react to clicks, 
however, the buttons itself are sensitive to cursor movements. I tried 
to set AreaBottomEdge to exclude the button area but when I do this, 
detection of the right button (as facilitated by RightButtonArea... 
settings in synclient) fails. Is there a way to exclude the button area 
from creating pointer movements and still allow the right button to work?

Below I'm giving you my synclient settings. Please let me know if you 
need any more info.

Any help or pointers is greatly appreciated.

Best regards
Markus
