Title:
  [Lenovo S431, 531, S5]: Brightness keys to not function properly.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  [Problem]:

  Pushing the brightness "down" key causes the brightess to immediately
  go to a value of 0 yet the actual brightness has not change on the
  screen.

  Pushing brightness "up" causes the brightness value to go up to around
  5% and immediately sets the actual corresponding brightness level on
  the display.

  At this point pressing the brightness "up" or "down" keys causes the
  brightness slider to jump between 0 and 5% but will not go any higher
  value setting.

  You have to open gnome-control-center "brightness and lock" to reset
  the brightness to desired value.

  This particular bug is present on a few recent lenovos models.
