Chromium makes it easy to be started in "kiosk" mode, that is to say to launch in full screen, without any window border, toolbar or notification (surprisingly, this feature is not offered by Mozilla Firefox).
Our goal will be to get:
- a minimal installation of the graphical server, without desktop environment or window manager;
- an automatic launch on startup, in full screen;
- no toolbar or notification.
To display the browser, we will have to install an X server. There is no need to install a desktop environment or window manager, unnecessarily large, since the browser will be launched directly in full screen.
sudo apt-get install xserver-xorg-video-all xserver-xorg-input-all xserver-xorg-core xinit x11-xserver-utils
To start the server automatically at startup, edit the `~/.bash_profile` file, which is executed when the user logs in, to put the following content (the server starts with `startx`, but it is also necessary to check that a screen is available to avoid an error, for example, with SSH):
if ( -z $DISPLAY ) && ( $(tty) = /dev/tty1 ); then
startx
fi
Your system must also be configured so that the user is automatically logged in at startup. How to proceed depends on your configuration.
We will install, of course, Chromium, but also `unclutter`, which will allow us to hide the pointer of the mouse:
sudo apt-get install chromium-browser sudo apt-get install unclutter
To start them automatically at startup, we create a file`~/.xinitrc` (this file is executed when the X server starts) which contains the following commands (take care to choose your URL and indicate the screen resolution) :
#!/bin/sh xset -dpms xset s off xset s noblank unclutter & chromium-browser /path/to/your/file.html --window-size=1920,1080 --start-fullscreen --kiosk --incognito --noerrdialogs --disable-translate --no-first-run --fast --fast-start --disable-infobars --disable-features=TranslateUI --disk-cache-dir=/dev/null --password-store=basic
The `xset` commands are used to avoid the automatic standby of the system, which will otherwise interrupt the display after a specified time.
The option `--window-size=` is essential, otherwise Chromium will only be displayed on half of the screen, despite the other instructions, in the absence of a window manager.
