Chris Stratford, this bug was reported a while ago and there hasn't been
any activity in it recently. We were wondering if this is still an
issue? If so, could you please test for this with the latest development
release of Ubuntu? ISO images are available from
http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please just make a comment to this?

Title:
8086:0116 [Dell Inspiron 14z (N411z)] Display brightness keys don't
generate evdev events after saucy upgrade
Status in “linux” package in Ubuntu:
Incomplete
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out of date (it references /usr/share/doc/udev/README.keymap.txt which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.
