Answering my own question, it would appear that you can set screen
blanking (DPMS) in the command-line/TUI tool, raspi-config...
pi at raspberrypi:~ $ sudo raspi-config
pi at raspberrypi:~ $ tail -2 .config/wayfire.ini
[idle]
dpms_timeout=600
pi at raspberrypi:~ $
In raspi-config, select "2 Display Options", then "D2 Screen Blanking",
then enable. The above change to .config/wayfire.ini seems to be the
net effect. The timeout is set to 600 seconds, and could probably be
changed to any reasonable value, and likely 0 would disable it again.
Funny that there wasn't a more obvious way to set this, via GUI screen
preferences.
