X11, Window Managers It has been one year and four days since X.Org 7.3 was released and a number of months since X.Org 7.4 was supposed to be released, but today X.Org 7.4 is scheduled to finally make it out the door! This release is shipping quite late and with a slimmed down set of features, but in this article we have more details on what this release holds in store for the Linux desktop community and why it may be a short-lived release.

Glucose, AFAIK, isn't needed anymore with the memory manager(s).

It was supposed to provide Xrender acceleration when AIGLX was running, by implementing it in OpenGL(using glitz?) and sending indirectly to X server which would run as part of its rendering context (so glucose is "indirectly" rendered). Same thing was done with Xgl, using glitz library to translate XRender calls to OpenGL.

Now, the new EXA-TTM(GEM,UXA?) plays nicely with memory manager which can now take offline pixmaps rendered by accelerated EXA Xrender and composite them with the window manager running on AIGLX. Same as with Glucose, if not even simpler and without GL indirection.

it is funny that nvidia which has been doing this as they have their own memory manager and probably have an architecture similar in function to uxa to accelerate render. Yet, using xgl is still faster than nvidia's render acceleration, especially as with the use of a compositing manager, the gpu is accelerating pure opengl only (not render+opengl)

Only the most recent beta drivers seem to be approaching the speed of xgl (using kde4).
