Actually you should be using Xlib. There are some tutorials around, just google for it. Xlib talks to the Xserver. The Xserver talks to a HAL type driver. I guess you could get the source code to the Xserver and be a replacement Xserver. But you would need to talk to the HAL driver. The HAL drivers talks to a driver supplied by the guys who made the video card. I have heard complaints that they don't open-source their drivers. But I have never looked into that. I really have never peeked inside Xserver, but I gather that you cannot talk directly to the graphics hardware.

I suggest you stick with Xlib.
