[RndTbl] Raspberry Pi OS 12 bookworm and Wayland - no screen saver?

[Gilbert Detillieux]

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.
