Hello everyone. This morning I installed a new AMD driver update. I believe it was the 15.7.1. update. After returning home from the day, I find I am unable to adjust my laptop's brightness, both via f2 and f3 on the keyboard and manually via the AMD Catalyst Center (I can move the slider, but nothing happens). I am using Windows 10. Is there a way to go back before I installed 15.7.1. or whatever it was or just re-install the older one instead? Thank you.
