Well, there hasn't changed a lot - at least for the basic stuff. A pixel
is still a rather crude dot on some bitplane. So if you still got some
old paper, use it. Beside that,  http://www.the-labs.com/ is a primer
source for online-information about X11 - at least if you got some prior
programming knowledge :)

Check:

Beside that, if you want to draw (vector based) stuff, the antigrain lib
( http://www.antigrain.com/ ) is worth a look. Extreme fast rendering and
complete OS independent.
