Small script, which starts slide as screensaver
pi-screensaver-slide needs xprintidle and slide (https://github.com/NautiluX/slide) to work.
- Change values at configuration section
- Run install.sh (or manually add this script to autostart of LXDE/-pi, see https://www.raspberrypi.org/forums/viewtopic.php?t=131659)
