Hmmm. For a while now we've had display calibration+profiling
applications compel full screen mode so they're not really usable
alongside anything else. They are in effect taking over. So if it's
possible for the calibration app to set aside the Wayland session, use
drm/kms full screen, and then restore the Wayland session I might be
OK with it. But if I have to log out, not OK.
