The X.Org project provides an open source implementation of the X Window System. The development work is being done in conjunction with the freedesktop.org community. The X.Org Foundation is the educational non-profit corporation whose Board serves this effort, and whose Members lead this work.
The current X.Org release is X11R7.7. The next major release will be X11R7.8. Information about all releases is available. (Important: If you have an older release, please see the Security page for information on security updates.)

Reporting problems, asking questions and getting help
Check to see if your question is answered in the FAQ.
Use the xorg product in the freedesktop bugzilla to report bugs against X.Org. (Gnome's bugzilla suggestions are well worth looking over if you are new to reporting bugs with systems like bugzilla.)

Development
The DeveloperStart page includes information for developers along with links to per-module developer pages.
Mailing Lists
On XorgMailingLists you can find a list of X-related mailing lists hosted on lists.freedesktop.org. More mailing lists on X Window System and related technologies along with subscription directions are available at XOrg Foundation.
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.

Sponsorship
The X.Org Foundation welcomes sponsorship (both cash and in-kind), and tries hard to put the donations of sponsors to transparent good use. The Foundation is an extremely low-overhead all-volunteer organization. If you are interested in contributing, please see our SponsorshipPage.
