I love my brand new laptop. Fast processor, m.2 ssd, memory to spare, xUbuntu runs great.
However, the tocuhpad is driving me nuts! As I'm typing the the mouse clicks on whatever window it's over. The worst part is that the feature "Disable Touchpad while typing" that should take care of this does not work.
Lets start with some specs:

Please note the the ETPS/2 Elantech Touchpad is disabled in the mouse and touchpad settings window. When ELAN1010:00 04F3:3012 Touchpad is disabled, the touchpad no longer works (so that is the one that is used.)
What I've tried (with it not making a difference):
- Standard "Disable Touchpad while typing" option in interface
- disabling above and running syndaemon -i 3 -DK
- disabling above and running syndaemon -i 3
- running syndaemon as root (just in case)
How I know if it works/doesn't work:
- Continuously tap one key in a window
- while doing the above tap on the touchpad in another window
- if focus changes to the other window, the touchpad is not disabling while typing
A couple theory's as to what may be happening:
- Touchpad driver is just plain not working right
- syndaemon disabling wrong touchpad entry (how to test/fix?)
- syndaemon not detecting keyboard activity (how to test/fix?)
I don't want to be a jerk when asking for help, but before someone suggests the "create a batch file to disable the touchpad and map it to a key" workaround. I already know about that, but it's just not a viable solution for me. Most of my time is spent clicking, typing a few lines, clicking again. etc. I am specifically looking to get disable touchpad while typing working. I am quite technical, have been using different flavors of linux for about 18 years, and have been programming for 20 years. However, I do not know the codebases involved and would love some help getting this tracked down.
