Fake screen saver on Raspberry PI
If you want to make fake screen saver to cover display you can use "feh" to do it.setup root cron:
17 16 * * * su - pi -c '/usr/bin/export DISPLAY=:0 && /usr/bin/timeout 120 /usr/bin/feh -Y -x -q -D 5 -B black -F -Z -z -r /media/pic/'
so It will activate screen saver for 120 minutes, displaying pictures from/media/pic folder starting at 16:17 everyday
