I was thinking about the video driver and vBox module interdependencies. It makes me think your Nvidia closed source driver may be why we could not compile the Oracle vBox module as part of apt install.
I cannot see how it would break the video module the other way around. Especially since the module build failed before it got a chance to compile anything. All is possible... I just do not see a causation. Unless, you would like to try breaking it by removing the oss vBox, installing Oracle vBox, then rebooting to see what happens. Followed by removing broken Oracle vBox and reinstalling oss vBox and rebooting. If it breaks your video, you will know what happened. If it doesn't you could still blame the weather in Mozambique.
