Public bug reported:

Brightness keys Fn+F4 and Fn+F5 (decrease and increase brightness) do not work on 13.10 and 14.04.
On 12.04 (up to 12.04.3) and 13.04 worked ok. 
That is, up to ubuntu repository kernel 3.8 the brightness keys worked ok.

On ubuntu repository kernels 3.11 and 3.13, the brightness keys do not
work. (this includes 12.04.4 that has kernel 3.11).

I currently have installed 14.04 with kernel 3.13.0-8.
