Description

B4 Q2D03 OS build-joyride-259

User choice of backlight brightness is lost as a result of the idle detection. Discussed in #olpc with cjb, this needs a change to get brightness, calculate an approprate lower value, and restore brightness, instead of setting to an absolute value.

By comparison, a MAC OS X laptop I have here will not dim below the minimum brightness setting.

Fix pushed to Joyride. We now preserve user choice of brightness after dimming, and don't dim if it would *increase* brightness.

Tested on 3 joyride-1520, Q2D08a machines with brightness level 2:

While being resumed, the back light would come back on to level 8. If press the adjustment key to make it darker, the screen immediately goes down to brightness level 1 with one key press.
