I also suffer from this bug. I have used 12.10 for the past year and upgraded to 14.04 but aside from the fact that it seemed generally buggy this did not work. Going over all the versions between 12.10 and 14.04 revealed that 13.04 is the only one where the brightness keys still work. After that they don't work on any other release.

Thank you for your reply. I will test kernel 3.15 and revert with news (probably later on today). In the meantime and after reading various reported bugs, I came accross this one: http://www.aristofunnies.gr/wp-content/uploads/2010/12/photo-12.jpeg It regards dell xps13, but refers to the exact same GPU (id 8086:0116). As you will read, the same problem persists especially on kernels after the 3.8, and they way to fix the fn function of the brightness keys in newer kernels is to set from the BIOS the Load Legacy Option Rom to Enabled. Unfortunately even if I have installed the lasted version of BIOS proposed by the DELL manufacturer (i.e. version A06), there is no option for legacy option. I am just throwing ideas. It may help you go towards the right direction for solving the bug. I will revert with news about the 3.15 kernel.

I installed today kernel 3.14.1. The problem is still present. I have not tried yet kernel 3.15 as it is in a very early (RC2) stage yet. I have also tried hundreds of grub parameters and conf files inside X11 (following the ARCH wiki here: https://wiki.archlinux.org/index.php/backlight) but still I could not make the brightness keys work. My opinion is that this is clearly a kernel problem. Something that will not be fixed by just adding parameters in grub etc. The buttons do not produce any kind of result in acpi_listen. Since this function was working just fine in earlier kernels, it must mean that there is a change or breakage as regards this aspect in the newer kernels. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1229591 Title: 8086:0116 [Dell Inspiron 14z (N411z)] Display brightness keys don't generate evdev events after saucy upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1229591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi. Thanx for your reply. Since I have exactly the same laptop with the same GPU (id 8086:0116) would it be better just to keep updating this bug report and provide additional info? (rather than opening a new bug report?) I could provide additional info by running: apport-collect -p linux #1229591 For your info I am using for the moment the ubuntu repository kernel 3.13.0-8.

I have exactly the same problem and exactly the same laptop. I would be very very happy to see this fixed at least for 14.04.

No change I'm afraid. I might be misunderstanding what those options do, but the problem isn't the backlight itself. As I stated in the original bug report, changing the value in /sys/class/backlight/intel_backlight/brightness does dim the screen (as does the slider in system settings / brightness lock). The problem is that the brightness function keys (Fn+F4 and Fn+F5) stopped working after upgrading to Saucy. Somehow, what appears to be a keyboard issue seems to have morphed into hunting for a backlight-related problem (unless the two are more intertwined than I think) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1229591 Title: 8086:0116 [Dell Inspiron 14z (N411z)] Display brightness keys don't generate evdev events after saucy upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1229591/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

For my Trusty test it would not have been used (at least not intentionally), as that was from a pure live CD boot. For all other tests, it would be.
