To narrow the problem, does eglinfo (from
http://cgit.freedesktop.org/mesa/demos in src/egl/opengl) say that
OpenGL_ES3 is an EGL client API? My Sandybridge system says

EGL API version: 1.4
EGL vendor string: Mesa Project
EGL version string: 1.4 (DRI2)
EGL client APIs: OpenGL OpenGL_ES OpenGL_ES2 OpenGL_ES3
