Vladimir, Your page looks very helpful. Thanks for putting it together. The only comment I have is regarding your first miscellaneous comment: "While hardware 3d is active nothing except your Xserver should be accessing your video card - or your system will lockup hard. In particular, frame grabber cards that write directly to video memory should be turned off. If you want to use these cards try out v4l module in XFree 4.x.x." I think the intent of this message is good for users--but it's misleading to developers trying to understand our architecture. To clarify, direct rendering is completely based on the idea of a client side driver accessing the hardware directly without using the Xserver to exclusively access the device. However, all access to the video device must be closely coordinated, and come from a suite of drivers that know each other well. Using drivers that don't cooperate closely, or even mixing older and newer driver components can introduce the lockups you describe. I hope this helps.
