Ubuntu Server for Digital Signage with Chromium starting fullscreen and Teamviewer

Install Ubuntu Server then

sudo apt-get update
sudo apt-get upgrade

Install X Server and openbox

sudo apt-get install --no-install-recommends xserver-xorg x11-xserver-utils xinit openbox

Install Chromium

sudo apt-get install --no-install-recommends chromium-browser

Openbox configuration

sudo vim /etc/xdg/openbox/autostart

File content to paste in autostart

# Disable any form of screen saver / screen blanking / power management
xset s off
xset s noblank
xset -dpms

# Allow quitting the X server with CTRL-ATL-Backspace
setxkbmap -option terminate:ctrl_alt_bksp

# Start Chromium in kiosk mode
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/' ~/.config/chromium/'Local State'
sed -i 's/"exited_cleanly":false/"exited_cleanly":true/; s/"exit_type":"[^"]\+"/"exit_type":"Normal"/' ~/.config/chromium/Default/Preferences
chromium-browser --disable-infobars --kiosk 'http://your-url-here'

If you want to try it run

startx -- -nocursor

Start X automatically on boot

sudo vim .bashrc

Add the following line to the file

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && startx -- -nocursor

If Chromium (or the X server) crashes, press Ctrl-Alt-Backspace to kill the X server and restart it with

startx -- -nocursor.

If you need a terminal session, you can switch to one of the other consoles by pressing Ctrl-Alt-F2 (or any other function key).

Pressing Ctrl-Alt-F1 brings you back to the first console where Chromium is running.

Autologin

sudo systemctl edit getty@tty1.service

Add the following, replacing myusername with your user name:

[Service]
ExecStart=
ExecStart=-/sbin/agetty --noissue --autologin myusername %I $TERM
Type=idle
