Bug Description
When pressing fn+brighten, fn+darken on laptop, the brightness first gets adjusted, then the osd pops up and restores previous setting and after a delay changes it again. If pressing rapidly, brightness alternates between two strengths until osd-control has caught up.
Changing through /proc/acpi/
Sometimes when changing with keys, the control gets confused and darkens instead of brighten, or vice versa.
cat /proc/acpi/
levels: 100 60 20 28 36 44 52 60 68 76 84 92 100
current: 76
1. hardy 8.04, intrepid 8.10
2. unkown
3. Change of brightness without delay
4. Change of contrast has delay, and also jumps between levels.
