Title:
  HP Envy 23 AIO - No way to dim display

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  There is a test for cert that dims the display automatically to 50%
  and then raises the brightness back to 100%.  This test failed to
  change the brightness at all on the Envy 23.

  I then tried using the Brightness and Lock too in the System Settings
  menu, and the Brightness slider had no effect at all on the display.

  There is no working method to alter screen brightness.
