Kiosk Computer

If you have any questions or get stuck as you work through this in-class exercise, please ask the instructor for assistance. Enjoy!

Installing Necessary Software

In order to set up the Raspberry Pi as a Kiosk Computer, you will need to significantly alter the Pi’s software. The first handout has instructions on how to do so: http://bit.ly/2MCdL7r
Firstly, prepare the pi by entering these commands:
```
sudo apt-get clean
sudo apt-get autoremove -y
```
Now the latest versions must be installed, to do so, enter the command sudo apt-get update
This may take a while, so as it is updating, let’s set up the slides we will display.
- You can display any website you like, or you can use a google slideshow.
- You can either create one now or use this one here: http://bit.ly/dsc-signage2

Once the Pi is done updating, install xdotool and sed using this command:

sudo apt-get install xdotool unclutter sed
sudo apt-get install x11-xserver-utils

Navigate to the autostart directory, to do this, enter the command
```
cd /etc/xdg/lxsession/LXDE-pi/
```
Now, enter the command sudo nano autostart

In this nano editor, copy in these lines:

@chromium-browser --kiosk --incognito [your url]
@xset s noblank
@xset s off
@xset -dpms
@unclutter -idle 0.1 -root

Now save and exit from nano by pressing “ctrl” and “X” then “Y”.
Enter in this command to the command line: sudo nano /etc/lightdm/lightdm.conf
Add the following line to the end of the file, then save and exit: Xserver-command = X -s 0 -dpms
Reboot the Pi: sudo reboot
To exit kiosk mode, do the keystroke ctrl+w
It is best practice to run kiosk mode on a Raspberry Pi with no log in prompt and no valuable data stored anywhere on the SD card. This way it can boot into the kiosk screen without interruption.
