Comment 4 for bug 659780

Apart from the 8 instead of 15 steps, not really. But regarding this, I noticed something strange however. It seems like increasing or decreasing the brightness is done by two steps instead of one, that is when you compare it with the initial 15 steps you got. This means that when you start at maximum brightness (15) and you start dimming to zero, you got 15 - 13 - 11 - ... - 3 - 1 - 0. But when you increase the brightness once you reached zero (which is absolutely dimmed), you got 0 - 2 - 4 - ... - 10 - 12 - 14. As 16 is not a valid value, the maximum brightness you got is 14 instead of 15.
So although the 0.25.1 version does support the MacBook pro better compared to 0.25, version 0.24.3 is still more accurate.
