Re: bug 1263368

Even after updating kernel version 3.11.0-15.23, the brightness
regulation continues to work on an apparently random basis, never as
expected. One day, I find that the brightness can only be regulated by
using the System Preferences, as well as the 'right' and 'left' keys;
there is no slider to be seen on the monitor, and the Fn key does not
function. But then, the next time I start the computer, everything works
as it should – I press the Fn key + right or left, the slider is there,
everything works properly! Where can I find the random number generator
that's causing this?! 

With hope for some help and best regards
                                                      Fritz
