Fixed my problem. I was totally wrongfooted by the GLX 1.4 prescription
3.3.4 On Screen Rendering
To create an onscreen rendering area, first create an X Window with a
visual that
corresponds to the desired GLXFBConfig, then call
GLXWindow glXCreateWindow(Display *dpy,
GLXFBConfig c
Just to add to my mail of a few minutes ago. I had a look at the GLX 1.4
manual and glXMakeCurrent should never return a BadValue error.
I am even more foxed

Good to get on a sidetrack again. You are right. XF86 does appear not to
support rendering to GLXPixmaps with a direct context.
But I was using an GLXWin

It might have been a good idea to start with that in the first place. :)

I only called XF86...Capable to confirm that the software recognized my
video card as *capable* of direct rendering.

I think DRI is properly installed on my system, at least glxinfo
confirms Direct rendering: Yes.
As a first step I just want to draw a trangle in a
