Thank you for taking the time to report this bug and helping to make
Ubuntu better. The issue that you reported is one that should be
reproducible with the live environment of the Desktop CD of the stable
release - Oneiric Ocelot. It would help us greatly if you could test
with it so we can work on getting it fixed. You can find out more about
the development release at http://www.ubuntu.com/testing/ . Thanks again
and we appreciate your help.

Title:
  brightness keys don't work on HP Elitebook 8540p

Status in “gnome-power-manager” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: gnome-power-manager

  Pressing either the fn f9 (brightness down) or fn f10 (brightness up)
  results in the brightness control appearing on screen, however the
  brightness level is not adjusted, and the on-screen brightness slider
  does not change the position.

  Description:	Ubuntu 10.10
  Release:	10.10

  gnome-power-manager               2.32.0-0ubuntu1
  policykit-1                          0.96-2ubuntu1

  Running gnome-power-manager -v reveals this error when attempting to
  adjust the brightness level

  pkexec /usr/sbin/gnome-power-backlight-helper --set-brightness 23
  **
  ERROR:pkexec.c:124:pam_conversation_function: code should not be reached
  Aborted

  Running the command manually also results in the same error.

  Manually adjusting the brightness via the command line works, for example
  sudo echo 50 >/proc/acpi/video/DGFX/LCD/brightness
