I try to have good touchpad experience when enable "tap to click".
Here is my properties that I feel the touchpad would not annoy me when I typping.

In xinput:
Synaptics Tap Time: 60

In syndaemon:
PalmDetect = 0
PalmMinWidth = 7
ref: https://wiki.archlinux.org/index.php/Touchpad_Synaptics#Disable_touchpad_while_typing

More detail:
1. Synaptics Tap Time:
 The default value is 180.
 The "tap to click" is too sensitive.
 My tap time around 0.04 ~ 0.08 second.
 So, I set it to 60 (0.06 second).
 The side effect is the "tap to click" will lost function when the tap time longer than 0.06 second.

2. The syndaemon settings:
PalmDetect = 1
PalmMinWidth = 10
On XPS13, the touchpad won't sent out the z (pressure) value.
When I set the PalmMinWidth = 7. I feel the "tap to click" is seldom to be emit.
But, actually, I don't know if this is the effect of this value.
