I chose re running AV wizard from Advance options menu, had a hard time to go though the AV wizard as the screen was too big but I made it through. The system now as overlay UI and following is the output of the command.
dpkg -l | grep nvidia

I see, driver 304 in the list. not sure is that the one being used by system?
The system is running fine at the moment.
I would mark the post as solved. For now.
Do you still want me to create the ticket for the same? I think you said you already fixed it. If yes, I do not know how to submit a ticket
Need log in credentials for git.
