Version: unspecified (using KDE 4.5.1) OS: Linux For various reasons (external keyboard, kernel acpi bug), a user might be forced to use the desktop environment instead of the keys to adjust the brightness level. This should be very quick and easy to do. Reproducible: Always Actual Results: Scrolling over the battery meter's tray icon does nothing. Expected Results: Scrolling over the meter should adjust brightness in appropriate steps, in a similar way volume is adjusted now when scrolling over KMix's tray icon.
Wasn‘t there a debate about this and plasma developers decided against this so useful idea? Voted for that. It should work the same way KMix‘ icon adjusts volume. Yes, we have the Fn-keys but why not make a more consistent overall look? Scrolling the volume icon -> Adjust volume, Scrolling the battery -> Adjust power comsumption, i.e. screen brightness. It‘s not too far away from being logical.
