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"
EndSection
