The "Troubleshooting" menu item lets you select "basic graphics mode".
After a day of futzing, this was the only way to get to the
installation screen.  Using the regular install selection yielded disk
accesses (when I was trying with a DVD) and a black screen.

My assumption was that this would get me through the installation and
not set it forever and ever.

I've never been good at deciphering Xorg.0.log files, but ...

[  1638.443] (==) Matched nouveau as autoconfigured driver 0
[  1638.443] (==) Matched modesetting as autoconfigured driver 1
[  1638.443] (==) Matched fbdev as autoconfigured driver 2
[  1638.443] (==) Matched vesa as autoconfigured driver 3

Who do I tell which one is being used and then how do I manipulate it?

Oh, good idea.  Hang on ...

OK, see if this works:
