As was mentioned previously in the
Phoronix News, there were speculations AIGLX or Accelerated Indirect GL X could run atop Compiz/XGL. Rumors initially were that these were two impeding projects and would ultimately be Red Hat versus Novell competition, however, this is simply not the case. Christopher Blizzard has
posted that Kristian has managed to get Compiz running on AIGLX from the Fedora Rendering Project. It did not require many modifications and more information is available on the Free Desktop
mailing list.
