Actually, we have now integrated most Steam Deck OLED stuff quite well.
We are not sure, how this run on the LCD Steam Deck, but it should be improved.
In the future we will also add an own chwd profile to automatically detect OLED / LCD or any other device and configure to it needs instead of shipping an all in one package.
Would be cool, if you test and give some feedback.
@nekoh is mainly maintaining this package.
