What I am trying to achieve is this:
|------------------------------|
|                              |
|                              |
|                              |
|                              |
|                              |
|               |--------------|
|               |RIGHT SOFT BTN|
|---------------|--------------|

But motion is ignored like so:
|------------------------------|
|                              |
|                              |
|                              |
|                              |
|                              |
|------------------------------|
| No motion initiated in here  |
|------------------------------|

Looking at the function "is_inside_top_or_bottom_button_area" here:
http://cgit.freedesktop.org/xorg/driver/xf86-input-synaptics/tree/src/synaptics.c?id=xf86-input-synaptics-1.8.0#n1542

I see that only the "y" coordinate is checked, see comment:
/* We don't have a left button area, so we only check the y axis */

Best regards,
Joschi
