["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Max Oropeza, thank you for updating your BIOS. Could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.11-rc3

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your
understanding.

Title:
  [Gateway NV55C] Two backlight interfaces that wont adjust backlight.

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I couldn't get the backlight to work after I upgraded to 13.04.

  WORKAROUND: The only grub lines that seem to work are these:
  GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"
  GRUB_CMDLINE_LINUX="acpi_osi="

  I tried changing the grub parameters, and after several trys, nothing.
  I was asked to run     grep . /sys/class/backlight/*/* and got the
  results of:

  maxo@Dayman:~$ grep . /sys/class/backlight/*/*
  /sys/class/backlight/acpi_video0/actual_brightness:9
  /sys/class/backlight/acpi_video0/bl_power:0
  /sys/class/backlight/acpi_video0/brightness:9
  grep: /sys/class/backlight/acpi_video0/device: Is a directory
  /sys/class/backlight/acpi_video0/max_brightness:9
  grep: /sys/class/backlight/acpi_video0/power: Is a directory
  grep: /sys/class/backlight/acpi_video0/subsystem: Is a directory
  /sys/class/backlight/acpi_video0/type:firmware
  /sys/class/backlight/intel_backlight/actual_brightness:976
  /sys/class/backlight/intel_backlight/bl_power:0
  /sys/class/backlight/intel_backlight/brightness:976
  grep: /sys/class/backlight/intel_backlight/device: Is a directory
  /sys/class/backlight/intel_backlight/max_brightness:976
  grep: /sys/class/backlight/intel_backlight/power: Is a directory
  grep: /sys/class/backlight/intel_backlight/subsystem: Is a directory
  /sys/class/backlight/intel_backlight/type:raw

  But using the Fn Keys, you can only adjust it a little, like from full
  brightness to about half. To add something else, with the other
  parameters when I adjust with the Fn Keys, the brightness bubble you
  get on the top right of your screen doesn't appear.
