No, they don't, and haven't for a long time now.

In fact, you can bypass X for a lot of drawing and have been able to for
years.  This is one of the major features of the XFree 4.x releases, and
pushed even further with Xorg 11R7.x.

OpenGL and DRI both go direct to the hardware, not through X.

In fact, if you have OpenGL, parts of X are now accelerated on top of it
instead.

There is talk to move X completely to this model.

One of the biggest benefits is it takes all of the driver complexity out of
X.  The first step is to remove all drivers from X, and put them under OpenGL.

It's a lot simpler this way.  Not only that, but now OpenGL can be used as an
independent graphics server for all kinds of different graphics systems.
Very flexible.

Of course, there would be pain involved, and open source politics would be a
difficult obstacle to overcome.
