I'm on the same laptop and on the latest version of stretch. My desktop environment is mate. I'm using the nouveau driver for my Nvidia card and not the proprietary driver.
Using the proprietary driver consistently borked my docking station setup and caused the main screen to flicker. This is not an issue with nouveau.
/sys/class/backlight is empty, xbacklight returns "No outputs have backlight property". I can't figure out any way to alter the screen brightness.
