Even with powerdevil 6.2.1-1 the system overrides my manual brightness settings on the monitors after powersaving or sometimes without any reason i am able to understand.
When i set the brightness in plasma, the problem appears that my 2nd monitor is also adjusted althogh it doesnt support brightness control - so a kind of grey layer is applied.
This is not a serious method. Calibrated colors and contrast a no longer valid.
