Maybe this is an -nvidia bug, but if so there's not much we can do about it at the distro level. So I think this would be better to be reviewed by the g-p-m guys first.
If it does turn out to be something to do with -nvidia particularly, it should be reported upstream - see http://www.nvnews.net/vbulletin/showthread.php?t=46678 ** Package changed: nvidia-graphics-drivers (Ubuntu) => gnome-power- manager (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/726692 Title: Screen backlight adjustment stopped working on MacBook Pro 5,4 and other hardware -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
