There was (not sure whether still is) an issue with the igt_kms library
that it kept the existing config, and that then lead to impossible
configs. I think we're now clearing just the sw state correctly though, so
doing it with a full commit (and all the time-wasting implied) would be
overkill.
Anyway, that was the reason, worth to double check this is indeed working
now. You probably need multiple screens to make it go boom.
