DetailsOn ASUS A8He isn't possible control rightness with xf86-video-intel-2.2.0-1, the 2.1.1-2 works fine. On virtual console it's working but if a Xserver is running it's broken.

I suggest you set xrandr to use the legacy method of accessing the backlight with:
xrandr --output LVDS --set BACKLIGHT_CONTROL legacy
OUTPUT CONFIGURATION
On 830M and better chipsets, the driver supports runtime configuration of detected outputs. You can use the xrandr tool to control outputs on the command line. Each output listed below may have one or more properties associated with it (like a binary EDID block if one is found). Some outputs have unique properties which are described below.
VGA
VGA output port (typically exposed via an HD15 connector).
LVDS
Low Voltage Differential Signalling output (typically a laptop LCD panel). Available properties:
BACKLIGHT - current backlight level (adjustable)
By adjusting the BACKLIGHT property, the brightness on the LVDS output can be adjusted. In some cases, this property may be unavailable (for example if your platform uses an external microcontroller to control the backlight).
BACKLIGHT_CONTROL - method used to control backlight
The driver will attempt to automatically detect the backlight control method for your platform. If this fails however, you can select another method which may allow you to control your backlight. Available methods include:
NATIVE
Intel chipsets include backlight control registers, which on some platforms may be wired to control the backlight directly. This method uses those registers.
LEGACY
The legacy backlight control registers exist in PCI configuration space, and have fewer available backlight levels than the native registers. However, some platforms are wired this way and so need to use this method.
COMBO
This method attempts to use the native registers where possible, resorting to the legacy, configuration space registers only to enable the backlight if needed. On platforms that have both wired this can be a good choice as it allows the fine grained backlight control of the native interface.
KERNEL
On some system, the kernel may provide a backlight control driver. In that case, using the kernel interfaces is preferable, as the same driver may respond to hotkey events or external APIs.
