fennel/fennel14: Disable Zero Finger Click Disable zero finger click to avoid mechanic issue around the touchpad: Namely hold the device and shake it intensively, it would generate false input events, which potentially causes an involuntary UI event from user's perspective. This patch disable "Zero Finger Clicks" to mitigate ghost events; even click is reported physically, the higher level gesture-interpreter will suppress it so there will be no fingers action on the UI layer. BUG=b:174507423 TEST=emerge and deploy, check conf install onto DUT, intensively shake device while watching stream video, make sure video won't suddenly stop playing while no fingers touch the touchpad.

This repository contains configuration files that were originally for the X Windowing System (a.k.a. X11 or Xorg). CrOS moved away from using X around 2015, but these files are still used to configure input devices. Thankfully this reduction in scope greatly reduces their effect on life satisfaction.
The syntax is now a subset of Xorg's configuration syntax, and using anything outside of that subset will either cause an error or just be ignored. Specifically, only InputClass
sections are supported. Within those, the following entries are supported:
Identifier
;Match
directives (MatchProduct
, MatchDevicePath
, MatchUSBID
, MatchIsPointer
, MatchIsTouchpad
, and MatchIsTouchscreen
);Driver
, which is ignored; andOption
, which is used to specify gesture properties instead of X11 input device options (though some old X11 options may be hanging around).For more details, see the parsing code in Chromium's GesturePropertyProvider
