I have been occasionally trying to follow developments of various graphics technology in Linux. Compared to competitors, Linux lags behind graphically on the desktop.
Recently various X developers have often talked about new developments such as EXA, xgl, egl, xegl, glitz among others. This has become a bit confusing since some of these are complimentary technologies but some are competing altertatives. None is finished and available yet and there is still debate about which are better anyway.
I keep checking fairly regularly to see if there is anything I can download and test yet. Looking at xorg list indicates that EXA support is now being added to most popular drivers.
Two interesting things happened today. Firstly, a patch for EXA support for the radeon driver was posted. (most of my gfx hardware at home is radeon based) The second thing was a post to LKML by Jon Smirl linking to a summary of what all these technologies are. It gives a good explanation which has certainly clarified things for me, even if he does appear a little biased against EXA. (perhaps understandable for a egl/xgl developer)
