I have an issue with the screen brightness of my computer. I have a Dell Inspiron 7520. I have a AMD Radeon HD 7730m 2gb with a Intel HD 4000, I am currently using the kernel lastest kernel from X-edgers I believe. 3.7 something like that. Anyways, this isn't the problem. I'm sure there's a way to change the level of brightness from the terminal, or even just change the range, cause it looks the be range that isn't enough. In fact, when I try to lower the brightness, it drops but slightly but it doesn't go lower on the bar. If I want to make the screen go brighter, well it can't because it is at the max.

this is unfortunately no answer to your problem, but i have the same laptop model and i also tried out the 3.7 kernel, because i have problems with the fan which is all the time running at full speed (did you solve that?). i experienced the same thing with the brightness. i swiched back to the 3.5 kernel. there it works fine.
