  [Compaq Presario CQ60-300EO Notebook PC] kernel doesn't recognize
  backlight fn keys

Status in linux package in Ubuntu:

Bug description:
  I'm using Ubuntu 15.04 and fn+f7 and fn+f8 use to lower and higher the brightness of the screen.
  In slackware using kernel 3.14.33 those keys works and give output from acpi_listen.
  In kernel 3.16 to 4.0 those keys don't work and acpi_listen outputs nothing.

  I expected fn+f7 and fn+f8 to work
