Also, during the black screen the mouse is sluggish and the keyboard is not responsive until desktop finally shows (not even ctrl-alt-F2), except the num-lock key does turn light on and off. Caps lock has no affect.

Another thing is that after clicking unlock on the greeter the mouse cursor jumps to a location near the top right corner (about 1" down and half inch over) on 19.10 and to center of screen on 20.04 and that cursor shows as the correct cursor type for what will be at that location when the screen finally shows up (so if a terminal is at that location it will show as the I shaped text cursor).

And I do get some log activity during the black screen, so my PC isn't locked up totally, but there is nothing consistent.
