Synaptics Touchpad configuration

[Malcolm Matalka]

I'm curious how to properly configure a laptop with a synaptics
touchpad.  The wikipage suggests using moused and turning off X11
Synaptics driver.  Is this still the proper setup?  There is also a man
page for the X11 synaptics driver so it seems like that is still
supported?

The reason I ask is that by using the wiki setup I'm having issues with
palm detection.  I've tweaked my settings a lot but I cannot get around
stray mouse clicks cased by my palm while typing.  I've even got
settings to the point where it is almost difficult click intentionally
but I still get stray clicks.

My current sysctl's are below and I'm using a Dell XPS 9370.
