Hi brs-sebascova (and community). I apologize for the late response, I didn’t realize there would be a response so quickly. Although I did download the latest drivers from Nvidia’s website, the preferred method is to go through the Linux Distro’s depository. And there’s the problem. I am getting repeated error messages (which I won’t go into here- specifically a Linux issue) that I have to solve/work around before I can upgrade. Hopefully I will have this solved and get back to you all regarding the original issue of the error message after shutdown. To be continued…
