Thomas Christensen, bugzilla is legacy, and largely ignored by upstream
developers. As well, it holds none of the information requested by
upstream, as previously and fully documented to you in
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1181927/comments/21
. Instead, you would want to utilize the kernel.org format and repost to
the linux-acpi mailing list with the latest mainline kernel results.

Title:
  [Aspire V5-431]13.04: Brightness control visible but does nothing

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Brightness control visible but does nothing on 13.04...

  The brightness up down buttons shows the overlay brightness icon going
  up and down but it does not change the brightness (backlight).

  I have tried adjusting the kernel options acpi_osi=<x> and
  acpi_backlight=<y> (that did work with 12.10) to make it work but to
  no avail.

  WORKAROUND: echo 20 > /sys/class/backlight/intel_backlight/brightness
