On my ACER laptop with windows 10 and an AMD HD5000 card. The possibility to change screen light has stop working after migrating to windows 10.
it worked before with windows 7. If I now with windows 10 force machine to use the basic Microsoft graphical driver it also works. But with the latest, downloaded yesterday, drivers from AMD it does not.
Could it be a flaw in the latest driver pack from AMD?
If you use Fn + "key for light up/down" the onscreen symbol get present and you see that it moves up and down accordingly. Changing sound with Fn + "sound up/down key" it works.
