# AUR Package Manager
|
||||
|
||||
This project uses some packages from the Arch Linux AUR repos. As such, we are going to setup a package manager for those packages. Pacman doesn't support the AUR repos natively and this is the most accessible approach for installing AUR packages.
|
||||
|
||||
The commands below will setup the ```yay``` AUR package manager.
|
||||
|
||||
``` sh
|
||||
|
||||
pacman -S --needed base-devel go
|
||||
useradd yay -s /usr/bin/nologin
|
||||
mkdir /home/yay
|
||||
chown yay: -R /home/yay
|
||||
git clone https://aur.archlinux.org/yay.git /opt/yay
|

chown yay: -R /opt/yay/

# Base Firmware Setup
|
||||
|
||||
The ```PiFrame``` uses Arch Linux at its core. This document will outline a way to setup a micro sd card with Arch Linux.
|
||||
The ```PiFrame``` uses Ubuntu Linux at its core.
|
||||
|
||||
# Please Note
|
||||
There are a lot of documents online on how to flash Ubuntu to an sd card for the Raspberry Pi 4.
|
||||
|
||||
We assume you're going to use the Raspberry Pi itself for setting up an Arch Linux environment. In order to do this properly and safely, you'll need 2 micro sd cards and a USB to micro sd card adapter.
|
||||
|
||||
# Setup an Ubuntu SD Card
|
||||
|
||||
The first step is to setup a basic Ubuntu boot environment for the Raspberry Pi, we will use this to boot strap (initialize) the Arch Linux micro sd card. This Ubuntu micro sd card can also be used to recover a broken Arch Linux system if necessary.
|
||||
|
||||
1. Download Ubuntu from their main [download site](https://ubuntu.com/download/raspberry-pi/thank-you?version=20.04&architecture=arm64+raspi) and flash it to the sd card. There are a lot of guides on how to do this online.
|
||||
1. Boot the Ubuntu installation
|
||||
1. Check the ip address with ```ip addr`` and ssh into the environment if desired. This step can be skipped if you have a keyboard/monitor setup.
|
||||
1. Login to the Ubuntu envrionment
|
||||
1. Open a terminal
|
||||
1. Run ```sudo -sHu root``` to elevate your privileges
|
||||

||||

|
||||
|
||||
## Arch Linux Disk Setup
|
||||
|
||||
Run the following commands to prep the Arch Linux micro sd card. Please note the device nodes like ```/dev/sda``` may be different depending on the usb adapter used.
|
||||
|
||||
``` sh
|
||||
|
||||
parted /dev/sda
|
||||
mklabel msdos

q
|
||||
|
||||
mkfs.fat /dev/sda1
|
||||
mkfs.btrfs /dev/sda2
|
||||
|
||||
```
|
||||
|
||||
## Arch Linux Bootstrap
|
||||
|
||||
Run the following commands to bootstrap (initialize) a fundamental Arch Linux installation.
|
||||
|
||||
``` sh
|
||||
|
||||
mkdir /mnt/arch
|
||||
mount -o nodiratime,noatime,compress /dev/sda2 /mnt/arch
|
||||
mkdir /mnt/arch/boot
|
||||
mount /dev/sda1 /mnt/arch/boot
|
||||
cd /mnt/arch
|
||||
wget http://os.archlinuxarm.org/os/ArchLinuxARM-rpi-4-latest.tar.gz
|
||||
tar -xpf ArchLinuxARM-rpi-4-latest.tar.gz
|
||||
rm ArchLinuxARM-rpi-4-latest.tar.gz
|
||||
|
||||
```
|
||||
|
||||
## Tweak Bootstrapped System
|
||||
|
||||
The following commands will tweak the base Arch Linux distro to facilitate the needs of a photo frame as well as tune some of the debugging that's present in the default setup.
|
||||
|
||||
``` sh
|
||||
|
||||
cat > /mnt/arch/boot/config.txt <<EOF
|
||||
# KmN: Borrowed some stuff from majaro

|
||||
|
||||
# Make sure hdmi low power mode is set for when the feature is implemented on the Pi4
|
||||
hdmi_blanking=1
|
||||
|
||||
# you may need to add hdmi settings specific to your lcd display panel
|
||||
# for example, the below settings are for a 2560x1600 50Hz panel
|
||||
# see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md
|
||||
# for additional details
|
||||
#hdmi_cvt=2560 1600 50 5 0 0 1
|
||||
#hdmi_group=2
|
||||
#hdmi_mode=88
|
||||

||||
|
||||
nano -w /mnt/arch/boot/cmdline.txt
|
||||
root=/dev/mmcblk0p2 rootflags=nodiratime,noatime,compress rw rootwait
|
||||
remove kgdboc=ttyAMA0,115200
|
||||
|
||||
|
||||
parted /dev/sda
|
||||
set 1 boot on
|
||||
set 1 lba on
|
||||
set 2 lba on
|
||||
q
|
||||
```
|
||||
|
||||
## Boot Arch Linux
|
||||
|
||||
That should do it for the bootstrapping process. You can now shutdown the Ubuntu environment via ```systemctl poweroff```, swap the micro sd cards and boot into the Arch Linux environment.
|
||||
|
||||
You should not need the Ubuntu micro sd card at this point unless you need to recover or fix a broken Arch Linux installation.
|
||||
**Please Note: You'll want the most recent LTS 64bit server version of Ubuntu for your PiFrame**

# Slideshow
|
||||
|
||||
The below commands will setup ```feh``` as a slideshow on your display.
|
||||
The below commands will setup ```fim``` as a slideshow on your display.
|
||||
|
||||
## Important Notes
|
||||
|
||||
* ```feh``` will crash if there are no photos for it to use as a slideshow
|
||||
* You will likely want to tweak the ```feh``` command invocation below. These are great settings as a starting point but you'll probably want to make adjustments for your use case.
|
||||
* This setup uses ```incron``` to restart ```feh``` when photos are deleted from the pictures folder. Without this piece ```feh``` will crash if a picture is removed from the pictures directory prior to ```feh``` rescaning the pictures directory.
|
||||
* We default to ```DejaVuSansMono``` as the font for display of EXIF data and filename. This is an open font and looks great on most displays. Any ```fontconfig``` font can be used in its place. Adjust according to your preferences.
|
||||
* ```fim``` will crash if there are no photos for it to use as a slideshow
|
||||
* You will likely want to tweak the ```fim``` command invocation below. These are great settings as a starting point but you'll probably want to make adjustments for your use case.
|
||||
* This setup uses ```incron``` to restart ```fim``` when photos are deleted from the pictures folder. Without this piece ```fim``` will crash if a picture is removed from the pictures directory prior to ```fim``` rescaning the pictures directory.
