Welcome to chilipie-kiosk

Looks like this is your first boot!

This document lists some things you can do to customize your kiosk. You'll need to plug in a keyboard for this initial setup, but after that, it's perfectly fine to leave the kiosk running without any peripherals plugged in.

Setting the URL

Press F11 to exit the full screen mode, and Ctrl + L to focus the location bar. Navigate away! Once done, press F11 again to re-enter full screen mode.

Chromium is configured to remember the URL where you left off (and all logins, etc), so this might be all the configuration you need to do!

Getting to a terminal

You can get to a virtual terminal by pressing Ctrl + Alt + F2, and logging in with username pi and password raspberry. Use Ctrl + Alt + F1 to switch back to Chromium.

System configuration

Use sudo raspi-config in the terminal to do things like:

  • Join a WiFi network
  • Change the system timezone
  • Change your keyboard layout
  • Enable SSH access (it's disabled by default for security reasons)

Automating things

There's a few commonly useful snippets already on the crontab, such as:

  • Rebooting the Pi every night at 3 AM. If you run resource intensive pages on your dashboard, the Pi can eventually start to slow down. A nightly reboot keeps it rested and refreshed! This is enabled by default.
  • Turning the display off for the night. This helps save energy when there's no-one there to look at your dashboard. Sometimes also useful for reasons of vanity, when bright displays in the middle of a dark office would look ridiculous. Do make sure your display/television comes back on, however: especially older TV's sometimes won't know to automatically turn back on when the HDMI signal comes back on. In those cases, you may have luck with CEC signals, but also you may not. If nothing else works, you can always just blank the display.
  • Automatically reloading the active page every hour. If the page you're displaying doesn't automatically update itself, this is effectively the same as hitting Ctrl + R every hour. Very crude. Very effective.
  • Cycling between open tabs every 5 minutes. Same as above, but for Ctrl + Tab. Note that if you use both at the same time, you can combine them, to send the reload command just before sending the tab cycle command. This causes the pages to reload while they're in the background, so the user never sees it happening.

Use crontab -e to check these out, enable the ones you want, or customize them to your heart's content.

Customizing Chromium

Because you're running a fully-featured Chromium, you can customize it further by installing browser extensions. For instance, Tampermonkey can be useful for injecting custom JS or CSS to a page you're displaying.

Adjusting your resolution

If the display auto-detection fails and chooses a funky default resolution for you, there's a few things you can do to try and fix that.

Replacing the boot graphics

The image that's displayed while the kiosk is starting can be changed by just replacing ~/background.png.

To change the default chilipie-kiosk boot graphics to a nice doge, for example, try wget -O background.png https://bit.ly/2w1P4Il.

Increasing boot show delay

By default, the browser window is hidden for a few seconds after boot, to give the page time to load. You can increase (or decrease) this delay in ~/.xsession.
