Hi guys, I have a problem. I just installed Mavericks with #####, everything's fine. But my screen was kinda dark and I couldn't find the slider to increase screen brightness. So I patched DSDT and I got the brightness slider. But it was still dark even when I set max brightness. And there's a weird thing, while using Fn + F6 to increase screen brightness, I got the brightness as I want, but the slider didn't change. And if I tried using the slider, the screen got dark again.
How can I fix this? Thank you.
PS: My graphics card is Intel HD 3000
