Line 1: Line 1:
Once upon a time, long long ago, Linux users had to manually configure their X Window System in order to use graphical programs. Then came Linux distributions which provided install scripts that (most of the time) created a basic configuration file for the user, that they could then customize and/or fix. Today, we are transitioning towards a "config-less" X, that figures out everything those install scripts used to, but all inside X itself. #title X Configuration
<<Include(X/MenuBar)>>
Line 3: Line 4:
Of course, such a transition is not without some rough patches, and it's possible users may find themselves in a spot where they may still need to do some manual configuration. And that is what this page is for. Today's X rarely requires manual configuration. X now automatically configures itself with reasonable defaults. Both GNOME and KDE provide GUI utilities for customizing settings beyond these defaults if you like.

To create an initial /etc/xorg.conf file, you can have Xorg's autoconfiguration output a full blown static one for you:
{{{
sudo Xorg -configure
}}}

or create an /etc/xorg.conf containing only those sections and options that you need to override Xorg's autoconfigurated settings.

== Configuring using xorg.conf.d ==

Files ending in *.conf in the /etc/xorg.conf.d/ directory are automatically loaded by X at start prior to reading the xorg.conf. These files can each contain one or more Sections in the same format used by {{{xorg.conf}}}.

Users can continue making custom configuration in /etc/xorg.conf as usual; the .conf snippets are mainly there for the distro or hw vendor to ship custom overrides.
