Mmmh, the X11 startup has a "multiple different attempts" feature (trying with vesa, trying with no-ecore-vsync, etc...) options, which are not much tested but they are meant to work, in the end, it suggest to start a shell in failed cases
In other words, with this "auto" configurator should not be needed a configurator and it should manage it better, which they are very delicated (not always compatible). By other side it has not been tested much (not easy to simulate a "failed with intel, try with vesa" state but it should generate the configurations correctly by itself, see also this screenshot:
