The EGL driver you are using uses GLX protocol to get a list of
supported visuals from the server.

With i915, you might prefer

  $ ./configure --enable-gles2 --with-dri-drivers=i915 --disable-gallium

and be sure egl_dri2 is listed in "EGL drivers:" (which depends on
xcb-dri2 and xcb-fixes).

You may also want to use Mesa 7.10.
