I have found a workaround to ensure that the screen always comes up after resume from sleep: keep an application like Blender open. Perhaps it's because Blender uses OpenGL, which might have an effect on the graphics card upon resume, or in some other way it triggers whatever is necessary to make this laptop's screen work.
