How to hide desktop to show only black screen

Question

How to hide desktop or to show black screen so I can display images and videos by fbi and omxplayer without seeing desktop when next image is loaded?

Answer 1

You can try to switch off the backlight if available for your display. On the command line you can do it with:

rpi ~$ sudo /bin/sh -c 'echo "0" > /sys/class/backlight/soc\:backlight/brightness'

and on again:

rpi ~$ sudo /bin/sh -c 'echo "1" > /sys/class/backlight/soc\:backlight/brightness'

Answer 2

fbi doesn't need a GUI so don't use one.
