Creating a thin client terminal using Raspberry Debian OS, customized for industrial settings, leveraging the Raspberry Pi barebone built on ARM architecture.
Raspberry Pi OS Lite (64-bit)
Debian version: 12 (bookworm)
System: 64-bit
Kernel version: 6.1
Release: December 5th 2023
Compatible: 3B, 3B+, 3A+, 4B, 400, 5, CM3, CM3+, CM4, CM4S, Zero 2 W
Utilizing the official Raspberry Pi Imager program version 1.8.1 to install the image onto an 8 GB SD Card for system deployment.
2023-12-05-raspios-bookworm-arm64-lite.img.xz
This will give you a list of the disks and volumes inside or connected to your computer. The Pi SD card will contain a Linux partition under TYPE NAME:
diskutil list
diskutil unmountDisk /dev/diskX
Now you’re ready to duplicate the SD card, saving it as a disk image file on your hard drive:
sudo dd if=/dev/rdiskX of=2024-01-27-terminal.img bs=1m
Re-flashing the SD card then becomes:
sudo dd if=2024-01-27-terminal.img of=/dev/rdiskX bs=1m
Essential configurations for Raspberry Debian-based systems.
User: pi
Password: [PASS]
Using the configuration utility, access advanced settings for both the barebone hardware and Debian OS to ensure optimal SD card storage utilization, with automatic file system expansion during installation.
sudo raspi-config
raspi-config :: 3 Interface Options :: I1 SSH
raspi-config :: 6 Advanced Options :: A1 Expand filesystem
To address special key issues, such as arrow keys and delete functions, within the console editor, you can use the following commands:
For the current user (pi):
echo "set nocompatible" > ~/.vimrc
echo "set backspace=indent,eol,start" >> ~/.vimrc
For the root user:
sudo su
echo "set nocompatible" > ~/.vimrc
echo "set backspace=indent,eol,start" >> ~/.vimrc
To improve network identification, change the default hostname 'raspberrypi' to 'terminal' using the following commands. Replace 'raspberrypi' with 'terminal' and save the file:
sudo vi /etc/hostname
terminal
sudo vi /etc/hosts
127.0.1.1 terminal
Ensure that the changes take effect immediately, you can either log out and log back in or reboot your system
sudo reboot
Automatically installs essential dependencies required for compiling applications from source code on Linux Debian systems, ensuring a smooth and successful compilation process.
sudo apt-get install -y build-essential
sudo apt-get install -y make
sudo apt-get install -y automake
sudo apt-get install -y cmake
sudo apt-get install -y git
sudo apt-get install -y checkinstall
sudo apt-get install -y unzip
sudo apt-get install -y libtool
Update the software repository using the following command which update library dependencies, clean and purge system libraries:
sudo apt-get update
sudo apt-get autoremove -y --purge
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get clean
sudo ldconfig
To set up a minimal X-Window system, use the following command. This command will install the necessary components for a minimal X-Window environment without additional recommended packages.
sudo apt-get install -y --no-install-recommends xinit xserver-xorg
Install the graphical Xterm console with the following command:
sudo apt-get install -y xterm
Once installed, you can enhance the console by adjusting colors and font settings in the following file:
vi ~/.Xresources
These adjustments will help you customize and improve your XTerminal experience. NOTE: Leave a space at the beginning and end of the file!
XTerm*background: black
XTerm*foreground: WhiteSmoke
XTerm*faceName: DejaVu Sans Mono
XTerm*faceSize: 10
XTerm*renderFont: true
Para que los cambios surtan efecto, debes fusionar el archivo .Xresources con tu base de recursos actual ejecutando desde XWindow:
xrdb -merge ~/.Xresources
Raspberry Debian Linux Thinclient system should now be using SPANISH (es_ES.UTF-8) as the default system language and have the correct time zone set to Europe/Madrid.
In the configuration dialog, scroll down and find es_ES.UTF-8 in the list. Use the arrow keys to select it and press the spacebar to mark it with an asterisk (*). Press "Tab" to highlight the "OK" button, and then press "Enter" to confirm your selection:
sudo dpkg-reconfigure locales
Navigate through the menu to find EUROPE and then select MADRID. This will set your time zone to Europe/Madrid:
sudo dpkg-reconfigure tzdata
Set system default language and character encoding permanent in operatin system environment:
sudo vi /etc/bash.bashrc
# System Default Language
export LANGUAGE="es_ES.UTF-8"
export LC_ALL="es_ES.UTF-8"
export LC_CTYPE="es_ES.UTF-8"
export LC_LANG="es_ES.UTF-8"
export LANG="es_ES.UTF-8"
Set keyboard layout to SPANISH with Debian command-line utility:
sudo dpkg-reconfigure keyboard-configuration
Generic 105-key (Intl) PC ->
Spanish ->
The default for the keyboard layout ->
No compose key ->
Control+Alt+Backspace to terminate the X server? NO
Ensure that the changes take effect immediately, you can either log out and log back in or reboot your system
sudo reboot
Disabling terminal/console switching in Windows is preferable for the user experience of a thin client system. It prevents users from accessing unnecessary features, simplifying the user experience to the essentials.
Open or create the file /etc/X11/xorg.conf using the following command:
sudo vi /etc/X11/xorg.conf
Add the following lines inside the file:
Section "ServerFlags"
Option "DontVTSwitch" "true"
EndSection
The Openbox window manager for XWindow is a minimalist option that consumes only 7MB of memory, making it ideal for low-capacity devices like Raspberry Pi. After installing Openbox, you can apply the 'win10mod.obt' theme to give your windows a Windows 10-style appearance.
To install Openbox, use the following command:
sudo apt-get install -y openbox
For VNC server functionality, we recommend using x11vnc.
Install necessary fonts and VNC server:
sudo apt-get install -y xfonts-75dpi
sudo apt-get install -y xfonts-100dpi
sudo apt-get install -y x11vnc
Create a password for your VNC access credentials:
x11vnc -storepasswd
In Raspberry 5, if you're trying to build up an X11 GUI-ful on Bookworm Lite, you may have already discovered that it doesn't work, while the exact same disk popped into a Pi4 works as it always has, and the GUI comes up.
The error in Xorg.0.log is:
Cannot run in framebuffer mode. Please specify busIDs.
sudo apt-get install gldriver-test
Nos vamos a la utilidad de raspi-config y establecemos las opciones de X11 como systema de ventanas por defecto.
sudo raspi-config
Raspi-Config :: 6 Advanced Options :: A6 Wayland to X11
Desde la utilidad raspi-config podemos preparar el arranque automatico en modo grafico. Instalamos el gestor de login para poder disponer del arranque automatico grafico:
sudo apt-get install -y lightdm
Nos vamos a la utilidad de raspi-config y establecemos las opciones de arranque automático
sudo raspi-config
Raspi-Config :: 1 System Options :: S5 Boot / Auto Login :: B4 Desktop Autologin (pi user)
XWindow desactivar modo reposo (pantalla negra) y configurar el box para evitar que se active el modo reposo:
sudo vi /etc/lightdm/lightdm.conf
[Seat:*]
xserver-command=X -s 0 -dpms
This will set your blanking timeout to 0 seconds and turn off your display power management singling. Se puede modificar el tiempo de 0 a n segundos para configurarlo.
[EXTRA] Start X-Window with x11vnc with password authentication, repeat, sharing, and continuous operation:
starts & x11vnc -usepw -repeat -shared -forever &
Para comenzar hay que disponer de la estructura de directorios y recursos necesarios para poner en marcha el sistema thinclient. Descomprimir el archivo control-terms.tgz que contiene toda la estrucutra y ficheros necesarios para el sistema:
git clone https://github.com/jalopezsuarez/RaspberryTerminal24.git
mv RaspberryTerminal24/control-terms/terms ~

Los sistemas de inicialización SysV o Upstart están prácticamente en desuso, o al menos la intención es migrar a systemd. Aún se conservan servicios con scripts de inicio SysV y distribuciones que prefieren Upstart para inicializar y administrar los niveles de ejecución. Por defecto Debian (Raspiban) ya tiene preinstalado systemd para la gestion de servicios.

Con el siguiente scripts se automáticamente en cada inicio del sistema se sincronizaran todos las configuraciones que existan en la utilidad Remmina como enlaces en el escritorio. Basicamente limpirara todos los accesos existentes en iDesk (.idesktop) y convertirá todos los enlaces de Remmina en accesos directos preconfigurados (.remmina). El archivo que deberá ejecutarse cada vez que use inicie el sistema de ventanas OpenBox (autostart.sh) /home/pi/terms/bin/remmina.py contiene un script que sera necesario ejecutarlo al inicio de cada sesión para sincronizar los accesos remotos.
import os
import shutil

Plymouth presents a graphic animation (also known as a bootsplash) while the system boots:
sudo cp ~/terms/share/plymouth/darwin-170649.tgz /usr/share/plymouth/themes/
cd /usr/share/plymouth/themes/
sudo tar zxvf darwin-170649.tgz
sudo rm -rf darwin-170649.tgz
sudo plymouth-set-default-theme darwin
sudo update-initramfs -u
sudo vi /boot/cmdline.txt
El contenido del archivo original es el siguiente (cambiando el PARTUUID por el correspondiente):
console=serial0,115200 console=tty1 root=PARTUUID=fb5e9b5d-02 rootfstype=ext4 fsck.repair=yes rootwait
Add following commands after rootwait:
loglevel=0 vt.global_cursor_default=0 logo.nologo quiet splash plymouth.enable=1 plymouth.ignore-serial-consoles
Here are brief explanations:
loglevel=0: removes most of the messages from the boot
vt.global_cursor_default=0: removes blinking cursor.
logo.nologo: removes Raspberry Pi logo in top left corner.
quiet: disable boot message texts
splash: enables splash image
plymouth.enable=1: enable Plymouth splash
plymouth.ignore-serial-consoles: if you are going to use Plymouth, add this.
You might also try adding the following to /boot/config.txt to disable the rainbow splash if it bothers you:
sudo vi /boot/config.txt
# Suppress splash/warnings
disable_splash=1
avoid_warnings=1

Graphical User Interface (GUI) tool designed for configuring Wi-Fi networks on the Debian Linux system. It is built upon the QT libraries from the KDE environment and serves as a graphical frontend for interacting with wpa_supplicant. This tool enables users to query the current network status, modify configuration settings, and request interactive user input when needed.
sudo apt-get install -y wpagui
This issue, indicated by the message "RTNETLINK answers: Operation not possible due to RF-kill," can occur on Raspberry Pi 3B and 3B+ models, potentially leading to WiFi dysfunction.
Try Enabling the Wireless Interface: After ensuring that there are no blocks (either hardware or software), try to bring the interface up again with:
sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operación imposible por estar la radiofrecuencia desactivada
sudo ip link set wlan0 up
RTNETLINK answers: Operation not possible due to RF-kill
Check RF-kill Status: Use the rfkill command to check the status of all RF devices on your system, including wireless interfaces, to see if they are blocked.
sudo apt-get install rfkill
sudo rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: yes
Hard blocked: no
Unblock RF Devices: If the device is blocked by software, unblock it using:
sudo rfkill unblock wifi
