Hi All The solution from wvengen does work perfectly for me. I also have a macbook pro 5.5 and at the moment I'm running Ubuntu 13.10. My Nvidia Driver at the time of typing is 304 but I will try 319 soon. Just install git via: "sudo apt-get install git" if no already done. Next step is clone the mentioned repo. So type:
git clone https://github.com/guillaumezin/nvidiabl.git Next step is to install the latest package in the install/deb folder. First enter the install/deb folder via cd nvidiabl/install/deb next is to actually install the driver via sudo dpkg -i nvidiabl-dkms_0.85_all.deb if a newer version (higher number thant 0.85) is available install this one instead. After installation has completed one needs to restart and backlight control does work again :) Credits go to guillaumezin and wvengen for coding and pointing me to the solution. I'm very greatfull for your work and pointing me to the solution after Hours of research. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-313-updates in Ubuntu. https://bugs.launchpad.net/bugs/1171729 Title: no backlight controls with nvidia driver on MacbookPro5,5 Status in “nvidia-graphics-drivers-313-updates” package in Ubuntu: Confirmed Bug description: With the open source nouveau driver, the backlight control in /sys/class/backlight/apple_backlight works.
