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.
