With GLVND, whenever we have both Mesa's and NVIDIA's drives installed in the system, initializing the GBM backend will always succeed, regardless of what GPU you have on your system. This is due to GBM's software rendering fallback. It seems better to initialize the EGLDevice backend first, which will fail to find a device match when given a non-NVIDIA GPU. https://bugzilla.gnome.org/show_bug.cgi?id=784272
