The X.Org project provides an open source implementation of the X Window System. The development work is being done in conjunction with the community. The X.Org Foundation is the educational non-profit corporation whose Board serves this effort, and whose Members lead this work.

The last full release of the entire X.Org stack was X11R7.7 - since then individual X.Org modules have been released independently as needed - see the xorg-announce archives for details of those releases, and for downloads. Information about all releases is available. (Important: If you have an older release, please see the Security page for information on security updates.)

Getting X

The best place to get X is from your operating system or distribution vendor. X.Org currently provides no binaries.

There are many Mirrors from which you can download source code to the X Window System. If you would like to be a mirror, feel free to do so and add yourself to the Mirrors page.

Development snapshots are currently on hiatus; most modules now update slowly enough that frequent snapshots aren't needed.
