Are there touchpad-specific drivers for the Dell XPS 13 9350, beyond the generic Windows 10 drivers? I don't see any on the web site and contacting technical support only resulted in running a bunch of diagnostics. My touchpad works fine on the generic drivers except that I can't horizontal scroll (e.g. going through folders in File Explorer). Is this normal or are there laptop-specific drivers that improve functionality? For example is the touchpad Synaptics, Elan, etc.? Thanks...please respond as this is bugging me...lol.
