Oh maybe we could fix this in Plymouth without disabling the laptop display...

If the CRTC_X / CRTC_Y / CRTC_W / CRTC_H properties behave how I think they should then we could use them to maintain correct aspect ratio and each monitor in its own native preferred resolution.

For example, displaying a 1920x1080 buffer in a 1920x1200 mode:

  CRTC_X = 0
  CRTC_Y = 60
  CRTC_W = 1920
  CRTC_H = 1080

Maybe those only exist for atomic KMS drivers though (like i915).
