Fixing a Pi on site
Get to the console or desktop with a keyboard, for example to change Wi-Fi.
When a Pi moves to a new building or the Wi-Fi changes, it can’t be reached over SSH. Fix it from the Pi itself:
- Plug a USB keyboard into the Pi and press Ctrl+Alt+T. Ctrl+Alt+F1 through F12 work too.
- The slideshow stops and the screen shows the console login. Press Enter if you don’t see a prompt, then log in with the Pi’s account.
- Change Wi-Fi with
sudo raspi-config, under System Options, Wireless LAN. - Bring the slideshow back:
sudo pi-display startA reboot brings it back too.
The desktop
If the Pi has the desktop installed (not Raspberry Pi OS Lite), you can use it instead of the console:
sudo pi-display desktopThe slideshow stops and the desktop starts, so you can change Wi-Fi and other settings with a mouse. It lasts until the next reboot, and the Pi still boots into the slideshow. To go back sooner, open a terminal and run sudo pi-display start.
While it’s offline
Media already on the Pi keeps playing from its local copy, so the screen shows the last synced files until the network is back. New files arrive within 30 seconds once it is.
