Jeremie Tamburini, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available (3.15-rc7) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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-3.15-rc6

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

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:
  [Fujitsu Lifebook A512] Brightness hot keys Fn+F6/Fn+F7 don't work

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Pressing Fn+F6 or Fn+F7 the brightness doesn't change.

  WORKAROUND: Execute at a terminal:
  for i in /sys/class/backlight/*; do echo $i;cat $i/brightness;cat $i/max_brightness;done

  shows this output:
  /sys/class/backlight/acpi_video0
  1
  100
  /sys/class/backlight/intel_backlight
  4882
  4882

  Create /usr/share/X11/xorg.conf.d/20-intel.conf to set the "intel_backlight" interface, which will make the brightness shortcuts Fn+F6 and Fn+F7 work:
  Section "Device"
          Identifier "card0"
          Driver "intel"
          Option "Backlight" "intel_backlight"
          BusID "PCI:0:2:0"
