Bug Description
Hello,
For some days, my brightness control do not work on mbp 6.2 + Lucid.
Although the brightness level is displayed in the upper-right corner of the screen when I press the F1 and F2 keys, the brightness level does not change at all.
However, trying sudo pommed -d in a terminal gives me:
KEY: LCD backlight down
LCD stepping -1 -> 29464
E: Not primary DBus name owner
KBD: inhibit clear 0x08 -> 0x00
KEY: LCD backlight down
LCD stepping -1 -> 29463
E: Not primary DBus name owner
when I press two times the F1 key (=>decrease brightness). So it seems the stepping (-1) is just too small compared to the number representing the brightness (here: 29464), the brightness control is just too slow to be visible on a human time scale..
Using f1 and f2 does change brightness levels, but the increment is tiny compared to the value.
