Title:
  Lenovo Ideapad S205] Brightness keys do not change brightness after
  the last update

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Using either the increase or decrease brightness key results in osd-
  message showing the slider value going up or down. However, the actual
  brightness of the screen stays the same.

  It worked before this update^
