FAQ

Q: How do I turn off or turn on the screen on Raspberry Pi OS Trixie / Bookworm?

A: In the Labwc or Wayfire graphical environment, you can control the display state using wlr-randr. Modify DSI-2 according to the system's detected output.

# Turn off the screen
wlr-randr --output DSI-2 --off

# Turn on the screen
wlr-randr --output DSI-2 --on
Q: What should I do if there is no display after connecting the screen?

A: Check the DSI cable orientation, power connection, and config.txt configuration. When using DSI0, you need to enable the overlay with the dsi0 parameter; when using DSI1, keep the default DSI1 configuration.
