Direct Graphics Access (I think). Just means your client application gets
direct access to the video hardware, the mouse hardware, etc, without any
intervention from X. You get raw mouse events. Raw framebuffers. No pixel
translations. No nothing. You do it all yourself.

Good for games, mostly.

It's nothing to do with DRI.
