Nope. You should specifiy EGL_RENDERABLE_TYPE (0x3040) in the test program.
It is default to EGL_OPENGL_ES1_BIT (0x1), and egl_glx only supports
EGL_OPENGL_BIT (0x8).

Those suffixed with _screen do not work with egl_glx. They requre
EGL_MESA_screen_surface extension. They should output better error message
though.
