GLX extension adds OpenGL commands to the protocol. So X clients can use
OpenGL.

XGL is an X Server built *on top of* OpenGL. Xegl and Xglx are two
flavors of XGL. To use XGL on desktop, you'll need "--enable-xgl
--enable-xglx".

What do you want to do?
1.  Enable X clients(applications) to use OpenGL ES + EGL?
or
2.  Make X Server itself use OpenGL ES + EGL for rendering?

I don't know of any open source solution for (2). And it is a
significant development effort.
XGL uses OpenGL(through glitz). Few months back, XGL support was removed
from the xserver master branch.
