I have an Asus N56VJ that exhibited the same behavior on 12.10. I installed kernel 3.7.0-7 from Xorg-edgers and the F5-F6 backlight keys now work correctly. I consider the backlight adjustment to be critical as in a dimly lit room, the screen is so bright it hurts your eyes.
I tried a 13.04 live distro from one of the magazine DVDs. Activating the backlight keys showed the previous incorrect behaviour as described in this bug. The Bios on this N56VJ is verion 203 and that is the only one shown on the Asus web site. I asked Asus support if there was a 214 update for this model and they said no. So I will not be doing 13.04. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1165590 Title: Unable to adjust backlight brightness after upgrade to raring - Asus UX32VD To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1165590/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
