UPDATE: I downloaded and burned a Kubuntu 17.10 Live DVD, and booted into it. Everything worked fine, the screen never went blank.
This is a relief because now I have a way to rescue the system (or the data) if and when that becomes necessary. A final word of thanks to @batman23 for the invaluable help. |
