Si hace unos dias hablabamos sobre XGL, ahora toca hablar de AIGLX.

AIGLX es la apuesta por el servidor X acelerado de RedHat.
Segun ellos AIGLX es:

AIGLX is a project that aims to enable GL-accelerated effects on a standard desktop. We have a lightly modified X server (that includes a couple of extensions), an updated Mesa package that adds some new protocol support and a version of metacity with a composite manager. The end result is that you can use GL effects on your desktop with very few changes, the ability to turn it on and off at will, and you don’t have to replace your X server in the process.

XGL is a different X server. This is a more incremental change which is slated to become part of Xorg. We don’t believe that replacing the entire X server is the right path, and that improving it incrementally is a better way to modernize it. After talking to people at xdevconf, it felt like much of the upstream Xorg community shares this view. You can search Adam Jackson’s notes for “large work for Xgl” to get the blow-by-blow or NVidia’s presentation from XDevConf 2006 on using the existing model.
