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).
This makes it possible to display a presentation, or a page, on a standalone display or on a terminal…
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
Launch at startup
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):
# ~/.bash_profile 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 platform.
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
Launch at startup
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 # ~/.xinitrc 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
xset commands are used to avoid the automatic standby of the system, which will otherwise interrupt the display after a specified time.
--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.
