Debian Kiosk

I have configured a kiosk using Debian GNU/Linux with blackbox window manager.

The challenges:
1. Touchscreen configuration.
2. Autometic login and start X server.
3. Start desired application for kiosk.
4. A boot splash for booting and shutdown.
 
1. Touchscreen configuration:
First, setup touchscreen driver and configure it according to your device specification.
I was using eGalax driver, which I have downloaded from

2. Automatic login:
Edit /etc/inittab and comment the following line:

#1:2345:respawn:/sbin/getty 38400 tty1

add the following line below:

1:2345:respawn:/bin/login -f USER_LOGIN tty1 /dev/tty1 2>&1 

Edit .bash_profile (create if require) and add the following line at bottom:

startx

Blackbox window manager:
Edit ~/.xinitrc (or ~/.Xsession), create if require, and add the following line:

exec blackbox

3. Autostart application:
To autostart iceweasel/firefox:
Again edit ~/.xinitrc (or ~/.Xsession) and add the following line:

firefox &
exec blackbox

source: http://blackboxwm.sourceforge.net/BlackboxFAQ/StartupAndShutdown

Install iceweasel/firefox plugin “R-kiosk” from https://addons.mozilla.org/en-US/firefox/addon/1659

3. Bootsplash:
Install a bootsplash

apt-get install splashy

Create your own bootsplash and set it

# splashy_config -c

To enable splashy, you may need to edit grub.config and add the following after “kernel…ro quiet”

vga=791 splash

Tips and tricks:
“X: user not authorized to run the X server”
You can allow the user to use run startx by:

#dpkg-reconfigure x11-common

or edit  /etc/X11/Xwrapper.config

allowed_users=anybody 

“Auto login problem”
 If you have setup GDM (XDM) earlier, then you need to disable it for automatic log in

#update-rc.d -f gdm remove

If you want to enable it simply run (experiment purpose):

#update-rc.d -f gdm defaults

Kiosk performance tuning:
Install the CPU frequency related tools and configure it.
