Please reproduce the bug from a boot without ever loading the Nvidia driver. If you can still reoproduce it then can you update the bug and confirm the adapter in use and what it is connected to (eg is this a panel with USB connector or an adapter to a monitor ?)
Can't recreate the identical symptom using either nouveau/intel/udl or even intel/udl, which would seem to suggest it isn't actually a bug in udl or even modesetting in general.
There are bugs with nouveau and intel, but the symptoms are obviously different and I'm guessing I should file seperate bug reports.
