Raspberry Pi in Browser Kiosk Mode with HDMI Monitor

// remove the cursor
sudo apt-get install unclutter

// install Google Chrome on Raspberry Pi
sudo apt-get install chromium

// Open Chromium in Fullscreen mode after booting the Raspberry Pi
sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

It should look like this:

@lxpanel –profile LXDE
@pcmanfm –desktop –profile LXDE
@xscreensaver -no-splash

@xset s off
@xset s noblank
@xset -dpms
@chromium –kiosk



// Disable Screen to become black

How to set dd (disc dump) verbose (mac / bsd / linux)

Because of the missing verbose mode in GNU dd there is an other application with verbose mode by default. It’s dcfldd.

dcfldd is an enhanced version of GNU dd written by Nicholas Harbour

I especially used it for duplicating Raspberry Pi SD Cards. Without dcfldd you don’t know what time it will take to create the backup or SD Card.

Running Example:

Mac:Downloads andreas$ sudo dcfldd if=RaspberryPi.img of=/dev/disk1 bs=512
1798144 blocks (878Mb) written.

How to install dcfldd:

  1. Download dcfldd-1.3.4-1 :
  2. tar -xvf dcfldd-1.3.4-1.tar
  3. cd dcfldd-1.3.4-1
  4. ./configure
  5. sudo make install clean

Raspberry Pi – set sound interface shell script

For selecting the audio output I wrote a little script.






if test $1  #check if parameter 1 / 0=auto, 1=analog, 2=hdmi is set

        echo "Try to select sound Interface:" $1
        sudo amixer cset numid=3  $1

        echo " select interface :" 
        echo "0=auto"
        echo "1=analog"
        echo "2=hdmi"
        read -p "Which interface should be used? " interfaceID
        echo "Try to select sound Interface:"  $interfaceID
        sudo amixer cset numid=3 interfaceID
