Hello, I use Fedora 41 KDE, recently I noticed a problem where laptop’s backlight stops working after sleep when on energy saving mode. After waking up it starts bouncing between max and low brightness until it turns off. Turning on performance mode fixed the issue but I feel that is the workaround and there should be a permanent solution.
