Martin Bångens, if you tested 14.04.1 that's fine, as I was trying to
find the most recent release where this was not reproducible. So, please
disregard the 14.04.0 test.

Despite this, the next step is to fully commit bisect from kernel 3.13
to 3.19 in order to identify the last good kernel commit, followed
immediately by the first bad one. This will allow for a more expedited
analysis of the root cause of your issue. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Please note, finding adjacent kernel versions is not fully commit
bisecting.

Thank you for your understanding.

Title:
  kernel don't recognize laptop backlight fn keys

Status in linux package in Ubuntu:
  Incomplete

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
