FYI this sort of works (had to suspend/resume a few times) on xps 15z
too (same touchpad AFAIK):
* two finger scroll works - needs to be enabled in "all settings -> mouse and
touchpad -> touchpad (tab)"
* pinch zoom works (with a vertical motion) in gnome image viewer - needs to be
enabled in "all settings -> mouse and touchpad -> touchpad (tab)"
* two finger tap does open context menu in firefox and gnome-terminal
* disable touchpad while typing works (two finger tap doesn't open context menu
while typing this comment)
* changing pointer acceleration (in touchpad config) works, but setting
acceleration & sensitivity to the max I expected (subjective) the curosr to be
crazy fast/sensitive.
Seems when the touchpad is correctly "recognized" (or whatever the term
is), everything works. But sometimes (after cold boot or resume), it's
recognized only partially e.g. cursor doesn't move, but clicks register,
but not where the cursor is.
