Just tried xubuntu 13.10 on the same laptop, keeping 12.10 on its partition to
boot on one or another as will.
Xubuntu 13.10 is freshly installed, not much customized but updates applied and
rebooted.
Kernel is 3.11.0-12-generic .
lsb_release -rd
Description: Ubuntu 13.10
Release: 13.10
On xubuntu 13.10, things that worked still work (hotkeys, etc), things
that were unusual did as on 12.10 (e.g. Fn-F7). The good news is that
Fn-F5 and Fn-F6 changed.
The following misbehavior that were true on 12.10 have changed:
> * pressing Fn-F5 and Fn-F6 *does not* show on-screen notification ->
minor
Now there *is* an on-screen notification.
> Fn-F5 (brightness down) cause no event seen by xev
Now it causes this:
MappingNotify event, serial 37, synthetic NO, window 0x0,
request MappingKeyboard, first_keycode 8, count 248
FocusOut event, serial 37, synthetic NO, window 0x3400001,

RRNotify event, serial 38, synthetic NO, window 0x3400001,
subtype XRROutputPropertyChangeNotifyEvent
output LVDS1, property Backlight, timestamp 848645, state NewValue
> Fn-F6 (brightness up) cause no event seen by xev
Now it causes this:

mode NotifyGrab, detail NotifyAncestor
FocusOut event, serial 41, synthetic NO, window 0x3400001,

mode NotifyUngrab, detail NotifyAncestor
KeymapNotify event, serial 41, synthetic NO, window 0x0,
keys: 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
RRNotify event, serial 41, synthetic NO, window 0x3400001,
subtype XRROutputPropertyChangeNotifyEvent
output LVDS1, property Backlight, timestamp 853274, state NewValue
Just in case this difference in behavior could be due to a different set of
installed packages, here is the an output on the working Xubuntu 13.10:

As you can see, the only difference is gnome-power-manager installed.

Title:
Brightness hotkeys not seen by kernel on Asus n55s, other hotkeys ok.
Status in “xserver-xorg-input-evdev” package in Ubuntu:
Confirmed
Bug description:
On an Asus n55sf, there is an issue with the handling of brightness
adjust keys.
## Severity: consistent annoyance for the target human user
Rationale:
* On this laptop, the most natural way to set LCD brightness (hotkeys)
*seems* to work at first.
* But the user's choice is consistently overriden.
* More precisely: it is overriden whenever, on batteries, there is a pause in
keyboard/mouse activity (e.g. when the user reads text on-screen, or comes back
to the laptop after a minute).
* Caveat: the problem is *not* the laptop dimming the brightness to
save power, this is expected behavior. The problem is, when user
provides events again, brightness is not reverted to value set by
hotkeys.
## Context
* X session, it can be Unity or other (e.g. xfce), scenario is the same.
* Bug noticeable when running on batteries (due to automatic brightness
change on idle).
## Expected behavior
* pressing Fn-F5 and Fn-F6 changes the brightness
* pressing Fn-F5 and Fn-F6 show on-screen notification
* on battery after 30 seconds without key/mouse event, backlight is dimmed.
Then, pressing any key or moving mouse restores brigthness at the value set
using keys
## Observed behavior
* pressing Fn-F5 and Fn-F6 changes the brightness -> OK
* pressing Fn-F5 and Fn-F6 *does not* show on-screen notification -> minor
* on battery after 30 seconds without key/mouse event, backlight is dimmed.
Then, pressing any key or moving mouse restores brigthness at the last value
set using software (gnome-control-center, xbacklight, whatever, but *not* the
brightness set using keys) -> bad
## Steps to reproduce
* set backlight to 100% (using gnome-control-center or "xbacklight =100"
(usage scenario : on AC, need bright display)
* unplug AC power to run on battery
* change brightness using Fn-F5, e.g. some value halfway (usage scenario :
now on the move, need to save power)
* count a little more than 30 seconds without touching
keyboard/touchpad/mouse, see brightness reduces to minimum
* press e.g. shift, or move mouse or touchpad
* expected : brightness jumps to halfway (set using hotkeys)
* observed : brightness jumps to maximum (set using software)
## Additional information
* Other keys work: sound volume, wifi toggle, touchpad toggle, sound
play/pause/previous/next/stop
* Some working keys *do* display OSD feedback (at least volume up/down/mute,
touchpad toggle, sound play/pause/previous/next/stop)
* Some working keys do not display OSD feedback (wifi toggle, supend, LCD
toggle, LCD/external display toggle)
* On a different laptop, Asus X77VN, brightness keys do show on-screen
notification with percentage bar, and the bug is never experienced.
Laptop is different model but same brand and software, same packages,
same system and user settings (Unity or xfce, same behaviour).
## Interpretation
* Everything seems consistent with the interpretation that although
brightness hotkeys do work, Ubuntu is never aware of that. So when
Ubuntu changes the brightness, it can not do better than use the value
set using software.
## Workaround
* In gnome control center, uncheck "Dim screen to save power". A quick
test shows that Ubuntu does not change brightness, so user preference
set by hotkey is preserved.
