After some trial and error, I was able to get the on-off switch to respond (!).
After even more trial and error, I was able to launch the flash drive with Ubuntu 22.04, by selecting a boot-up option I'd never selected (or even seen?) before: UEFI: Generic Flash Disk 8.07, Partiion 2. Ubuntu 22.04 loaded. From terminal, I entered
and this is what I got:

I *know* there's something there. The purple Ubuntu load screen with the row of bubbles loads at start-up, and re-appears when I shut down.
