How can you prevent the console switch to hires which disables the
LVDS display?

so no crtc->config or pipe_config

        !intel_pipe_config_compare(dev, &crtc->config, &pipe_config)) {
            WARN(1, "pipe state doesn't match!\n");
            intel_dump_pipe_config(crtc, &pipe_config,
                                   "[hw state]");
            intel_dump_pipe_config(crtc, &crtc->config,
                                   "[sw state]");

Any ideas on why?
