Well, you say you're running an up-to-date F22. And, I think, you've said it used to work OK but has been giving you trouble at some point after the initial install.
If that is the case, then booting to a LiveCD of the original F22 should not fail. I would try that first as well as trying a LiveCD of F23 which is the current version.
Oh, one more thing.....
I just noticed that on a laptop that I have if I set the brightness to MAX in the system-settings (I'm using KDE) but I use the FN key of the laptop and use the brightness UP/DOWN keys on the laptop I can control the brightness of the screen even though the settings remain at MAX.
So, maybe you have a laptop HW Function that you can play with?
