Apparently I can't reproduce this, so idk

Ok now I get it, kde has introduced the protocol thing that modifies the backlight of desktop monitors attached by displayport, just like laptops, but I've never seen this before on a desktop computer, for some reason one of my monitors remembers the default brightness, the other one does not, and this caused the bug when the power interrupted, so not a kde bug
