I am using a Macbook (Aluminum Late 2008 version) and dual booting ubuntu 12.10
After installation the keyboard controls for volume and brightness worked perfectly,but a few days later the brightness got stuck on high and it's been giving me headaches and is super annoying. I can't use the keyboard controls for brightness or change it in the settings. I've tried searching for a fix but nothing has worked so far. Any suggestions?
Also i have played around with the graphics drivers and i'm currently using: NVIDIA binary Xorg driver. Should i change this?
(Go easy on me, i'm a newbie :))
Graphics: Nvidia GeForce 9400M/integrated/SSE2
OS Type: 32-bit
I'll provide any extra information needed

♡ I found a solution! Hopefully someone finds this useful. I probably did more steps than required but here is what worked for me. ♡ (Nvidia users only)
Open Terminal and enter the command below to open the xorg.conf file for editing:
Once the file opens, find Section “Device” and add
(as shown below in bold line), and hit CtrlS to save it.
In my case, this file was empty so I entered the exact text and saved it to
/etc/X11
.Source
After restarting, if this did not work for you I also did the following:
Just create a file in
/etc/X11/xorg.conf.d/50-nvidia.conf
with the following content:Again, in my case some of these files didn't exist so I created them myself. When everything was in place I restarted and now my brightness controls are working
In order to create them manually open terminal and enter:
From there on navigate to:
/etc/X11/
and create a folder namedxorg.conf.d
. Then inside that folder create a file named50-nvidia.conf
using gedit with the content listed in the step 3.Now restart your computer.
