--- Comment #1 from Daniel <daniel-other+kde...@dadosch.de> --- Can confirm this. I think there are a couple of separate issues: 1. The screenbrightness of external screens isn't affected when changing the screenbrightness using the applet or the hardware keys. (wishlist) 2. When setting the screenbrightness using xrandr, while redshift/Night color is active: The screen gets darker, but the color temperature is totally off (too much blue, when it should be more red) (bug) 3. Redshift reset the brightness which was set by xrandr after about 10-30 seconds. (bug) Marcos, please note, that KCM_Nightcolor doesn't change the screen brightness yet AFAIK, but the color tone (see #413165) -- You are receiving this mail because: You are watching all bug changes.
