Public bug reported:

My laptop is an HP Pavilion dv6 TR7040x.  Every time I (re)boot into
Ubuntu 14.04, the screen brightness is set to maximum.  This happens
independent of my earlier setting.  I reduce the brightness, and
continue my work.  When I reboot, it is reset to maximum brightness.

This is a regression, and has existed since the daily builds of early
February.  On the same laptop, Ubuntu 12.04.4 does not exhibit this
problem.
