--- Comment #27 from Luca Viggiani <lviggiani at gmail.com> ---
@Jani: sorry again, I've read more carefully your comments and saw that will
most likely flow into 3.15.

For now I've created a custom systemd service as workaround on Arch Linux:

*******
/etc/systemd/system/brightness-fix.service :

[Unit]
Description=Fixes intel backlight control with Kernel 3.14

[Service]
Type=forking
ExecStart=/usr/bin/brightness-fix
TimeoutSec=0
StandardOutput=syslog
#RemainAfterExit=yes
#SysVStartPriority=99

[Install]
WantedBy=multi-user.target


*******
/usr/bin/brightness-fix :

#!/bin/bash

echo 0 > /sys/class/backlight/intel_backlight/brightnes
