I presume the following tests with es2gears_x11 are using EGL, right?

I attached the output of es2_info. es2tri and es2gears_x11 open a window and
display a color triangle, respectively the rotating gears. glxgears works as
well.

> I assume OpenGL apps on GLX work just fine?
If glxgears is enough to verify that, then yes.

> Have you ever built and installed Mesa manually, from source?
I think so, but I don’t think any artifacts of that remain. I verified that no
files matching *mesa* or *dri* are in /usr/local. Also, none of the paths in
the weston output contain /usr/local.

Indeed, when adding --with-cairo=image, I can run weston under X11 (haven’t
tried it under DRM). I’ve attached the log output so that you can compare.
