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.

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.
