Touchpad issues

[drufusb]

Thank you evilbunny, I have been following that thread pretty closely and am looking forward to the update.

I did notice that the lower left corner of the touchpad can get stuck down/pressed, due to sticky material on the back side of the touchpad. When I checked by removing the back cover as per the wiki Accessing the Internals, I also did notice that its ability to detect touch events was worse when the laptop was on my lap vs a table or desk. But I am still getting random "clicks" when nothing is touching the touchpad, and I have made sure that it is not stuck in the pressed position.

I have also noticed that if I do press and hold the touchpad "click" down, I am better able to move the mouse around the screen and more touch events are registered, but that also causes all contents on the screen to be selected. When I release pressure from the touchpad and it "un-clicks", the mouse often quits responding to any light touches for moving the mouse around and no longer registers events for movement of mouse on the desktop.

When running evtest to look at the usb input device events, with no "clicks" pressed (that I can tell) on the touchpad, the output from the tool is:

At the end of the log it shows DOUBLETAP, but all I did was remove a single finger from touching the touchpad, I did not touch it with more then a single finger and I removed it without pressing.
Thank you all for your help in trying to figure this out, any help is greatly appreciated. I would like to not have to have an external mouse plugged in if possible, it makes it way less "take on the go" friendly.
