In contrast, the Audio indicator does appear when the Audio Up and Audio Down buttons are activated.

For example in Aggressive Powersave profile (Level set at 50% brightness, Dim Display after 2 mins, with screen off after 3 mins), afer 1 minute, the Brightness indicator appears, showing about 25%, then after another 30 seconds, the Brightness indicator appears, showing fully dimmed (0%). (These times are half the set times, which is probably a separate bug). If the mouse is then moved, the Brightness indicator appears, showing 50% level. Of note though, is that the screen brightness does not actually change when these indicator events occur; it stays at the same level throughout. When triggered manually by explicitly activating these profiles through mouse, menu or power button action, the screen brightness settings are again not followed. The screen brightness also does not change when different powersave profiles are selected. For example, with these settings: Powersave 75% Aggressive Powersave 50% Performance ??? the screen brightness stays at the same level as when the machine first started, regardless of which profile is activated. Note that the Performance level can't be stated, as the slider is absent in the settings dialog (see attached screenshot).

Screen brightness controls are not working with a Samsung NF310-A01AU on 11.4 M5, in KDE. These are the xev outputs for Brightness Up (Fn-Up Arrow) and
It works a bit with KDE4.6.0 on a Samsung NF310: The brightness can be dimmed, but only between very low (indicator at minimum) and very bright (indicator at maximum), not discreetly.

Brightness scaling works, but starts to scale down to the lowest/highest brightness available. Looks like a keyboard event<->brightness scaling hooks issue. E.g. no key release sent. The workarounds (force_release hack in sysfs) doesn't solve this here.
