Megathanks to Nathan Adams for post #14 on this page. My Unity desktop had been functioning perfectly since upgrading to 16.04 nearly 10 months ago, but it suddenly broke yesterday for no reason I can fathom. (Last system action I had performed was to enable the system firewall - ufw.) I tried uninstalling and reinstalling Unity and LightDM, but neither action solved the problem
Then I entered each of Nathan's 10 lines above in a terminal, and when the last line executed, Unity sprang back to life.
