sys-backlight 0.1

Control linux screen brightness from commandline

Set Linux display brightness from console
=========================================

The ``backlight`` program is a commandline interface to adjust your linux lcd
panels brightness through the linux kernel sys interface

Installation
------------

The ``sys_backlight`` package is written in Python and is
available on PyPI_ which means installation should be as simple as::

$ pip install sys_backlight
Getting started
---------------

The ``sys_backlight`` package can be configured with a configuration file
in the ini format. Here is a example of a config file:

.. code-block:: ini

# Default variables
[DEFAULT]
StepRelative = 2
StepAbsolute = 10
MinBrightness = 2
MaxBrightness = 100

The configuration file is loaded from the following location:

- ``~/.conf/backlight.ini``

The structure of the configuration file is as follows:

- The ``[DEFAULT]`` section has four items, all of which are optional
(``StepRelative``, ``StepAbsolute``, ``MinBrightness``, and ``MaxBrightness``).

- Currently two types of brightness control are supported:

1. The physical brightness of the backlight of laptop screens. This uses
the Linux sysfs_ virtual file system's `/sys/class/backlight`_ interface
to control backlight brightness. The only required item is
``sys-directory`` which is expected to contain the absolute pathname of
the directory that controls the backlight brightness of your laptop
screen (you'll have to figure this out for yourself).
