I am new to Ubuntu and recently installed it on my Mac.
I have ran all of the update i.e.: (apt-get update), and have as well installed the proprietary nVidia driver (nvidia-current-updates).
After having installed that driver, the brightness control stopped working (which seems to be rather common).
I have tried to tackle this issue for a while now, but have been unable to fix it.
I have followed the instructions in this post but to no avail: Brightness controls doesn't work on a MacBook Pro 5.5 (ubuntu 12.04 LTS)
When I run this command:
lspci -v | grep -i -A 15 vga
This is what I get:
Capabilities: <access denied> Kernel driver in use: nvidia Kernel modules: nvidia_current_updates, nouveau, nvidiafb
I have created and modified the xorg.conf file, and have added the lines mentioned in the other post, I have restarted the computer and pressed F1 and F2 but the brightness of the screen won't budge.
Any ideas what else I could do to solve this problem?
Thank you in advance for any suggestions!
EDIT: I have also tried all 6 steps in this link: https://help.ubuntu.com/community/MacBookPro5-5/Precise#LCD_Brightness_Control as well as https://help.ubuntu.com/community/MacBookPro5-5/Precise#Keyboard (for the keyboard keys)
