This is the eighth release of the new modular source code tree. The source code has been split into nine logical modules: app, data, doc, driver, font, lib. proto, util and xserver. Each of these modules contain one or more packages that can be configured, built and installed separately. Please see an X11R7.7 release site for a complete list of the tarballs.
For information on how to build the modular tree packages see the Modular Developer's Guide. This guide also contains information for developers who want to help improve the modular build system and modular code base.
The X source code for this and all releases/snapshots as well as development versions can also be accessed via the Freedesktop.org git repository. It's also possible to browse the freedesktop git repository.
To check out the latest development version, don't specify any tag.
Bugs should be reported to freedesktop.org's bug tracking system
using the xorg component. Before
reporting bugs, please check the server log file, which can be found at
/var/log/Xorg.0.log on most platforms. If you can't
resolve the problem yourself, send the entire log file with your bug report but
not the operating system core dump. Do not edit the log file as our
developers use it to reproduce and debug your problem. Please attach it
to your bug report.
