Hello,
I wrote this before but on the wrong place, sorry about that. Well the problem is still the same, thank you for taking a look at this:
I have a macbook 5,1 and I have ubuntu 12.04 only. Once booted I cannot increase or decrease the brigthness of the screen and mantains at its maximum but the graphics besides that works fine. What shall I do in order to fix that? Well I passed through some posts and did this on the terminal:
the file does not exist
I don't know what to do at this moment because I have almost no experience with linux and IF I want to keep on going with linux (which I will) I need to reduce the brightness of my screen because is killing me
Thank you for your help.!
