Title: display brightness keys don't generate evdev events after saucy upgrade Status in “linux” package in Ubuntu: Confirmed Bug description: On raring (and precise) the display brightness keys (fn+f4 and fn+f5) on my Dell Inspiron 14z turned the brightness up and down. After a saucy upgrade this no longer happens (I don't see the popup brightness bubble either). The other, similar keys (volume adjustment, etc) still work fine. Changing the values in /sys/class/backlight/intel_backlight/brightness works (temporarily - it gets reset after the screen lock kicks in) I tried following the instructions in https://wiki.ubuntu.com/Hotkeys/Troubleshooting but this appears to be out of date (it references /usr/share/doc/udev/README.keymap.txt which does not exist) Ubuntu kernel version bisect revealed: First bad Ubuntu kernel: 3.11.0-0.2 last good Ubuntu kernel: 3.10.0-6.17 The results of a commit bisect are pending. --- ApportVersion: 2.12.4-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: chris 2646 F.... pulseaudio DistroRelease: Ubuntu 13.10 EcryptfsInUse: Yes InstallationDate: Installed on 2011-11-18 (675 days ago) InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) MachineType: Dell Inc.
