[ubuntu] X.org Architecture Diagram

[millie95]

I've been somewhat confused by the acronyms and architecture of the Xorg server for years, so I've put together a map (PDF, zipped) of what I understanding of it. Interested in any comments or feedback.

Wow, thank you. Extremely helpful.

[millie95]

Thanks for the feedback. Here is a link to version 2, which covers a bit more topics.

If it's no secret, what did you use to create the graph?

As long as I can recall, EXA was introduce by Zack Rusin, former Trolltech employee.

http://en.wikipedia.org/wiki/EXA .

He actually work on Gallium 3D for Tungsten Graphic, and pushed another acceleration achitecture named Glucose (http://zrusin.blogspot.com/2006/08/g...-graphics.html) that other at
Tungsten Graphic found interesting (mean : contribute code).

Keith Packard created Xrandr (1.1, 1.2 and actually working on 1.3)

You must have put a lot of time in to this, but I'm not going to pretent I understand it

Cmap Tools, from http://cmap.ihmc.us/

Very cool. I've been spending some time this weekend trying to understand some of these concepts. I'm still confused but this is nice and helps a bit.

May I ask you where have you found the documentation for the topics you covered (very effectively) in your graph?

Thanks

That is very cool and very enlightening.

It makes me wonder why the compiz will not run on latest ati driver (9.7) when xinerama is used for multiple monitors on multiple gpus (randr1.2 is currently incapable of this task).

The offscreen pixmap capability does not seem to be compromised. Perhaps it is compiz looking for randr but finding xinerama and not knowing what to do. But that cannot be since the big desktop mode also disables randr, at least it did with the previous driver and that did not effect compiz.....but ati claims to have fixed some randr problems with his release....so maybe the driver is somehow losing the composite extensions when it switches to xinerama but the Xorg.0.log says they are loaded and offscreen rendering space is available...or maybe compiz is not seeing them anymore....

Hmmm....

So many questions are now ponderable when viewing these charts.

kudos to you millie95
