Since the F1 and F2 brightness keys and the slider applet also require additional HAL support to work, can someone please confirm whether it works or not by running:
$ cat /sys/class/dmi/id/product_name $ echo <value between 0 and 1023> | sudo tee /sys/class/backlight/nvidia_backlight/brightness That's because I got inconsistent reports so far. -- 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
