See [Up to date hardware recommendations - #6 by Ian-Max-Andolina](https://psychtoolbox.discourse.group/t/up-to-date-hardware-recommendations/3351/6) by Ian and my followup message for the likely fix. This is likely a Matlab bug, for which the workaround mentioned in that post is needed.

If that doesn’t work, i’d just reinstall the operating system, as maybe something got screwed up during your adventures in installing and uninstalling the proprietary drivers. Or you can buy priority support from us, so i can try to help you unmuddle this thing.

End of free advice for this thread from my side,
