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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
