Using the cubieboard (A10) to display class schedules and updates using chromium-browser in kiosk mode

First of all download an A10 image

e.g. one of these: http://linux-sunxi.org/Install_Ubuntu_Linux_for_Cubieboard

or here: http://linux-sunxi.org/Bootable_OS_images

or here: http://cubieboard.org/download/

The next step is to download and install LiveSuit (http://linux-sunxi.org/LiveSuit), which is an application to flash the NAND.

Start LiveSuite, select the downloaded image and press the FEL key when powering up (the FEL key is the one under the USB OTG port), The CPU automatically enters FEL mode. Livesuit will start to write the image to Nand on board.

After that, you will be able to log into your cubieboard, with the appropriate credentials. In my case linaro/linaro.

Depending on the image you used, you need to resize some partitions

sudo resize2fs /dev/nandc

sudo resize2fs /dev/nandd

sudo resize2fs /dev/nande

sudo resize2fs /dev/nandf

Now we are ready make changes and install software. These are the changes I made

1.) Change default password and root password using passwd

2.) Edit /etc/network/interfaces and set a fixed hardware address

           auto eth0

iface eth0 inet dhcp
   hwaddress ether xx:xx:xx:xx:xx:xx

You could use a generated mac address, which ifconfig will display.

3.) To enable autologin edit /etc/lightdm/lightdm.conf and add

autologin-user=<YOUR USER>
autologin-user-timeout=0

In a terminal run

sudo groupadd autologin

sudo gpasswd -a linaro autologin

4.) Install/uninstall software

sudo apt-get update

sudo apt-get install unclutter xvkbd -y icedtea-6-plugin vino x11-xserver-utils vino openssh-server

sudo apt-get remove xscreensaver

5.) To change the locale settings, run the following commands in a terminal

sudo locale-gen de_DE.UTF-8

export LANG=de_DE.UTF-8

export LC_ALL=de_DE.UTF-8

sudo update-locale

sudo dpkg-reconfigure locales

6.) reconfigure the time zone

sudo dpkg-reconfigure tzdata

7.) Modify your autostart. vi /etc/xdg/lxsession/Lubuntu/autostart

@lxpanel --profile Lubuntu

@pcmanfm --desktop --profile lubuntu

@/usr/lib/policykit-1-gnome/polkit-gnome-authentication-agent-1

@xset s off

@xset s 0 0

@xset -dpms

@xset s noblank

@ntpdate 0.de.pool.ntp.org

@/usr/lib/vino/vino-server &

@chromium-browser --kiosk --incognito --disable-translate --allow-outadated-plugins --disk-cache-dir=/tmpfs --always-authorize-plugins http://yourwebsite

The xset stuff is there to disable any screen saving mode.

ntpdate updates your time. As an alternative you coud install ntp daemon (apt-get install ntp)

vino-server is a vnc-server, so i can have a remote look at the screen.

An alternative to vino is x11vnc (apt-get install x11vnc), which did not work due to a bug. (It crashed on connect).

The last line starts the browser in kiosk mode and opens a certain website.

8.) If you are using vino, make sure you set appropriate preferences using

vino-preferences

9.) I also had some issues with screen resolution, so i created a xorg.conf in /etc/X11

Section "Monitor"

       Identifier      "Monitor0"

       ModelName    "Monitor Model"

       DisplaySize     240 320

       Option          "DPMS" "false"

       Option       "UseEDID" "false"

EndSection

Section "Device"

       #Option "ShadowFB"      "true"

       Identifier  "Card0"

       Driver      "fbdev"

       Option  "fbdev" "/dev/fb0"

EndSection

Section "Screen"

       Identifier      "Screen0"

       Device     "Card0"

       Monitor     "Monitor0"

    DefaultDepth    24

    SubSection "Display"

           Depth           24       

       Modes   "1280x1024"

    EndSubSection

EndSection

10.) Last thing I did, was create a crontab, which shuts down the cubieboard, a few minutes, before the TV-screen turns off. As the board is hooked up to the TV usb, the TV will turn on the cubieboard again in the morning. Yes, the TV has a timer function, so it turns itself on automatically.
