Raspberry pi learnings

Some life issues

• A RPi with an old firmware version may cause errors to create the SD card partitions with a latest raspbianOS full installed. The work around was to boot with a basic raspianOS and run rpi-update. More info can be found here

Create SD card with BSPWM

Dowloand and create

Get the latest version from here , preferable the Raspberry Pi OS Lite 64-bit

Decompress the image

xz -d <image>-arm64-lite.img.xz

Create the copy in the SD card

dd of=/dev/sdx if=<image>-arm64-lite.img status=progress

First boot it will resize and generate ssh keys, and reboot. If a screen is connected, will ask to: Select keyboard layout Create user and password

Start NetworkManager and setup network

sudo systemctl start NetworkManager
sudo systemctl enable NetworkManager
sudo nmtui

It’s also possible to change hostname

Enable and start ssh

sudo systemctl start ssh
sudo systemctl enable ssh

reboot

Install and setup

Update and upgrade the system

sudo apt update
sudo apt full-upgrade

Install and configure BSPWM

sudo apt update
sudo apt install -y bspwm sxhkd xinit lxterminal fonts-firacode feh \
fonts-font-awesome wget rofi chromium-browser cups neofetch cmatrix \
slurm glances nmap micro xsel xclip compton

This script should download and configure the BSPWM for raspbery pi

wget -O - www.33co.de/scripts/bspwm/setup | bash

RPi autologin

To create autologin when systemd is in charge

Create a directory:

mkdir -pv /etc/systemd/system/getty@tty1.service.d/

Create a configuration file:

nano /etc/systemd/system/getty@tty1.service.d/autologin.conf

Copy and paste this code, and change the $username:

[Service]
ExecStart=
ExecStart=-/sbin/agetty --autologin $username --noclear %I 38400 linux

Enable the service:

systemctl enable getty@tty1.service

RPi run startx after login

Edit .bash_profile

sudo nano ~/.bash_profile

Copy and paste this code

if [[ -z $DISPLAY ]] && [[ $(tty) = /dev/tty1 ]]; then
 exec startx
fi

Edit .xinitrc and make sure the DE is being executed

sudo nano ~/.xinitrc

Copy and paste this code

exec bspwm
