@WindPower: This isn't relevant, since you installed both drivers nvidia-bl-dkms and mbp-nvidia-bl-dkms. (If you didn't install the latter from the mactel repo, the version provided by the linux kernel should also have been sufficient.) However, until nvidia-bl 0.15.0 nvidia-bl didn't auto-load. mbp-nvidia-bl always does. So, if you added a line to /etc/modules for nvidia-bl, you ended up loading both drivers providing two interfaces in /sys/class/backlight. Furthermore, if the brightness keys didn't work, HAL has just used the wrong interface.
As of nvidia-bl version 0.15.1, I got auto-loading to work. That also means the package now installs a file in /etc/modprobe.d, that blacklists mbp-nvidia-bl. That's why your scripting approach doesn't work anymore - the driver you used is just missing. Finally, for some strange reason nvidia-bl doesn't work on some MacBook Pro 5 models. Probably those incorporating two graphics adapters. But due to a lack of information, I don't really know. That means, if you can confirm that nvidia-bl doesn't work (as you did), just deinstall it. There's no reason to have both drivers installed. Unfortunately, mbp-nvidia-bl is also known to not work on some Apple machines. That's why there are both in the repos. Btw: They aren't completely redundant. While nvidia-bl (in theory) should support a wide range of machine incorporating Nvidia graphics adapters (not just from Apple), does mbp-nvidia-bl only work on Apple machines. In contrast to his name, not just MacBook Pros with Nvidia graphics, but all models incorporating Intel processors. -- nvidia-bl-dkms 0.15.1 update breaks backlight https://bugs.launchpad.net/bugs/516354 You received this bug notification because you are a member of Mactel Support, which is the registrant for Mactel Support. Status in Mactel Support: New Status in Ubuntu: New Bug description: Since February 1st's 0.15.1 update of the nvidia-bl-dkms package, the backlight of the screen cannot be changed. This happens on my Macbook Pro 5-3 but also happens to the 5-5 model according to http://ubuntuforums.org/showthread.php?p=8756152 , so it doesn't seem very far-fetched to say that might happen to all Macbook Pros. Downgrading nvidia-bl-dkms to version 0.15 makes the screen backlight slider "slidable" again but it has no impact on the screen's actual backlight. Using Kubuntu 9.10 64-bit on a Macbook Pro 5-3 with kernel 2.6.31-17-generic (but it does the same on the previous kernels as well). _______________________________________________ Mailing list: https://launchpad.net/~mactel-support Post to : [email protected] Unsubscribe : https://launchpad.net/~mactel-support More help : https://help.launchpad.net/ListHelp
