EXA solution was to move to hardware acceleration with OpenGL for both 2D and 3D graphics with 2D graphics becoming just a subset of 3D rendering. Switching entirely over is unfortunately not so simple and not without some major obstacles. EXA was adapted from KAA, the KDrive Acceleration Architecture, from the experimental Freedesktop.org Xserver. Per the initial mailing list announcement, the goals are: Many XAA drivers had EXA support added for X11R6.9/7.0 and support continues to be added to more drivers. Making this transition as easy as possible was an important design consideration. UXA is a reimplementation of the EXA API
