DisplayConfigGTK allows you to configure the screens and graphics cards of your Linux/GNU system. The editing of the x.org configuration is done by the guidance backend which is developed by the KDE community.
Please report any problems or crashes in our bug tracker at Launchpad.
Getting DisplayConfigGTK into Ubuntu is a feature goal of Ubuntu Gutsy as specified. The specification includes an overview of the current features and our plans for the future.
The source code is hosted at Launchpad too.
