disabling clickpad with synaptics

Tue Sep 9 14:48:11 PDT 2014

Hello,
    I was using synaptics (syndaemon -d -i 1) for long time with the old 
notebook that had synaptic touchpad (Dell E6500). Now I have Lenovo 
Thinkpad T431s, which has clickpad built-in. Even if using
      syndaemon -d -i 1.0 -R
I often get the cursor unintentionally moved in the window I am writing 
in. Apparently, syndaemon does not fully disable the clickpad for the 
specified time. On the other hand, if I do
     synclient TouchpadOff=1
then the clickpad really get disabled, leaving only active clicks. I use 
this feature within udev when plugging-in external mouse 
https://wiki.archlinux.org/index.php/Touchpad_Synaptics#Disable_touchpad_upon_external_mouse_detection, 
but I guess syndaemon could be extended to "switch off completely" the 
touchpad for the specified time. Could this be implemented, or do you 
see another way to avoid unintentional cursor moves & clicks resulting 
in writing somewhere else?

Thanks a lot for any hint,

best regards,
                            Tomas
