X11, Window Managers A new acceleration architecture is being ported from kdrive by some QT developers, which will make composition managers like xcompmgr really fast and able to do some of the "display tricks" MacOS X has been doing for awhile.

Ok so I now have an okay-ish handle on what all these new components are supposed to do. People care about this, and people care about when it will be ready for them to use.

Xgl: Accelerates X through GL. Basically, if GL supports your vid card, you get liquid smooth eye candy effects

Cairo: Provides screen antialiasing. If you take a linux desktop now and look at any rounded corner, you'll see it's very jagged and pixelly (for a prime example, see rounded corners in metacity themes). Cairo fixes this kind of thing, making everything smooth and sexy.

KAA: First I've heard of this. It seems that it permits you to do some of the stuff that Xgl does but instead of using GL it uses...something else. Works on more hardware and makes composite managers fast, essentially bringing drop shadows and transparency effects to everyone who couldn't use them up until now because their video cards had poor linux support.

Does that sound about right?

Now what I'm interested in is timelines. I know that Cairo will be in GTK 2.8. The Gnome guys are very hesitantly suggesting its inclusion for Gnome hesitantly that it makes me think it might be pushed back to Gnome 2.14. But either way, within a year Linux will have OSX-like smooth graphics.

What about Xgl/KAA? The fact that KAA is a solution until Xgl is stable makes me think that KAA will be available soon, and Xgl in the distant future. Am I right?
