Chapter 3. Usage

GTK+ GUI

If GTK+>=2.4 is installed on your computer, the configure process will detect it, and build the

GTK+ application.

The GTK+ GUI is designed to be user-friendly, so it should be easy to use it. To launch this GUI,

simply type:

# gddccontrol

Gnome panel applet

If Gnome>=2.10 is installed on your computer, the configure process will detect it, and build the

Gnome panel applet.

The Gnome panel applet is useful to switch between different monitor profiles created with the

GTK+ GUI. To add it to your Gnome Panel, simply right-click on the panel, choose “Add to Panel”,

and select “Monitor Profile Switcher”.

Command line tool

The command line tool is useful for debugging purpose, and to create automatic scripts.

Note

We won't present everything you can do with ddccontrol, if you want more information, type:

# ddccontrol -h

Usage example

This example explains how to list all available controls and then change the brightness parameter.

List available controls

To list available controls, type:

# ddccontrol -p

This probes for available monitors, then takes the first probed monitor and lists controls supported

by it. This should give you an output like this (this example uses a Samsung Syncmaster 173P and a

nVidia GeForce FX 5700):

ddccontrol version 0.1
