You know… I used to be a darn good tech, back when I was in support. I seem to have forgotten the basics. I will do a new install and let y’all know what happens.
OK, unplugging the extra monitor lets the new install boot. Unfortunately, after it boots, it apparently performs a soft restart. All of a sudden, I am looking at the login screen. Log back in and everything is closed. Right now, I am using the live boot to access the internet and talk to you fine people.
