I agree - I've sent nVidia problems from bug #173652 to this bug. As I understand it, sony-laptop generates ACPI events for the key-presses but the script that it calls doesn't do anything to affect backlight brightness. I'm not sure who's responsible for setting LED backlight: sony-laptop or nvidia driver? Possibly the backlight is an SNC method http://tjworld.net/snc/ or a CMOS register http://tjworld.net/wiki/Sony/Vaio/FE41Z/HackingBiosNvram (please note, I am clueless here...)
And for those who set their 'brightness' with the nVidia tool, you are only changing LCD values, not LED values, i.e. you are changing the colours of the screen not the intensity of the backlight so there is no power saving (only eye saving!). -- Brightness keys on Sony Vaio with nvidia doesn't work https://bugs.launchpad.net/bugs/95444 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
