[[File:Schema of the layers of the graphical user interface.svg|upright=1.5|thumb|A display server, such as X.Org Server, implements the [[windowing system]] and serves its clients.]]
The modern [[X.Org Foundation]] came into being in 2004 when the body that oversaw X standards and published the official reference implementation joined forces with former [[XFree86]] developers.<ref>{{cite web|last=Coopersmith|first=Alan|title=The difference between Xorg and XFree86|url=https://blogs.oracle.com/solaris/the-difference-between-xorg-and-xfree86-v2|date=28 May 2004|access-date=17 September 2018}}</ref> X11R6.7.0, the first version of the X.Org Server, was [[Fork (software development)|fork]]ed from XFree86 4.4 RC2.<ref name="announceX11R6.7" /> The immediate reason for the fork was a disagreement with the new license for the final release version of XFree86 4.4, but several disagreements among the contributors surfaced prior to the split. Many of the previous XFree86 developers have joined the X.Org Server project.

In 2005, a great effort was put in the modularization of the X.Org server source code,<ref>{{cite web|title=X.Org Foundation Modularization Working Group|url=http://www.x.org/wiki/ModularizationWorkingGroup/|publisher=X.Org Foundation|access-date=6 February 2014}}</ref> resulting in a dual release by the end of the year. The X11R7.0.0 release added a new modular build system based on the [[GNU Autotools]], while X11R6.9.0 kept the old [[imake]] build system, both releases sharing the same codebase. Since then the X11R6.9 branch is maintained frozen and all the ongoing development is done to the modular branch. The new build system also brought the use of dlloader standard [[dynamic linker]] to load plugins and drivers, deprecating the old own method. As a consequence of the modularization, the X11 binaries were moving out of their own <code>/usr/X11R6</code> subdirectory tree and into the global <code>/usr</code> tree on many [[Unix]] systems.

In June 2006, another effort was done to move the X.Org server source codebase from [[Concurrent Versions System|CVS]] to [[Git (software)|git]].<ref>{{cite web|last=Høgsberg|first=Kristian|title=Doing git migration now|date=July 2006 |url=http://lists.x.org/archives/xorg/2006-June/016439.html|access-date=6 February 2014}}</ref> Both efforts had the long-term goal of bringing new developers to the project. In the words of Alan Coopersmith:<ref>{{cite web|last=Coopersmith|first=Alan|title=Some times it's a book sprint, other times it's a marathon|url=https://blogs.oracle.com/solaris/some-times-its-a-book-sprint%2c-other-times-its-a-marathon-v2|access-date=12 January 2019}}</ref>

{{quote|Some of our efforts here have been technological - one of the driving efforts of the conversions from Imake to automake and from CVS to git was to make use of tools developers would already be familiar and productive with from other projects. The Modularization project, which broke up X.Org from one giant tree into over 200 small ones, had the goal of making it possible to fix a bug in a single library or driver without having to download and build many megabytes of software & fonts that were not being changed.}}

In the 7.1 release, the KDrive framework (a small implementation of X written by [[Keith Packard]], which was not based on [[XFree86]] that X.Org developers used as a testing ground for new ideas, such as [[EXA]]) was integrated into the main codebase of X.Org server.

In 2008, the new DRI2, based on the [[kernel mode-setting]] (KMS) driver, replaced DRI. This change also set a major milestone in the X.Org server architecture, as the drivers were moved out from the server and [[user space]] (UMS) to the [[kernel space]].

In 2013, the initial versions of DRI3 and Present extensions were written and coded by Keith Packard to provide a faster and [[Screen tearing|tearing]]-free 2D rendering. By the end of the year the implementation of [[GLX]] was rewritten by Adam Jackson at [[Red Hat]].<ref>{{cite web |url=https://www.phoronix.com/scan.php?page=news_item&px=MTQ2OTY |title=The X.Org Server's GLX Is Being Rewritten |date=26 October 2013}}</ref>
