Comment 5 for bug 1799232

I'm currently going down the road of replacing the startech device. The only thing that made me wonder if it was a software problem is that using the 'screen display' utility to move one screen, apply, then revert, seemed to fix the problem, albeit temporarily.
I noticed while debugging on Windows that the same problem happens there, so that seems to suggest it isn't software...but the same trick to temporarily fix it, using the corresponding Windows utility to move the displays, does not seem to fix it.
I wonder if the ubuntu 'screen display' utility does some kind of 'reset' on the thunderbolt interface and/or the startech adaptor.
In any case, it is looking like hardware...what do you think?
