Archi3 Linux is a lean desktop environment for Arch Linux running on x86_64 or AArch64 systems. It is based on the window manager i3, and it is by design as lightweight as possible and thus only contains the absolutely necessary components, such as a status bar (Polybar), a file manager (Thunar), an application launcher (Rofi) - here you find a more detailed list of the contained software.

A browser, a mail client etc. do not come with Archi3 Linux. It is up to the user to install the applications of his/her choice.

Technically, Archi3 Linux is a package group that can be installed during the normal Arch Linux installation process - see here for details.

The table gives an overview of the software that comes with Archi3 Linux:

A browser, mail client etc. is not contained. It is up to the user to install the desired software on top of Archi3 Linux.

To ensure that the Archi3 system is running in a consistent and integrated fashion, it comes with a predefined configuration.

The i3 configuration of Archi3 is not opinionated in the sense that the i3 default key bindings are substituted by Archi3-specific bindings. Instead, wherever possible, the i3 standard is used.

In some rare cases, the default i3 bindings do not launch i3 default applications but Archi3-specific scripts ($mod+D is starting a Rofi-based application launcher instead of dmenu, for example).

The i3 modifier key can be selected by the user upon first login after installation via the i3-config-wizard.

It is up to the user to adjust the system configuration to his/her needs and desires. Read more about automation of Arch Linux installation and the utilization of meta packages.

The installation on x86_64 systems follows in essence the standard guide from archlinux.org, while the installation on AArch64 systems follows the platform and device specific installation procedures from archlinuxarm.org extended by parts of the standard guide.

The $ sign is used as system prompt.

1. Start the installation of Arch Linux on your machine (by following this guide, for example).

   For the rest of this guide, we assume that you have mounted the new root to /mnt. If that’s not the case in your environment, adjust the commands accordingly.

2. To install the basic system, execute

    $ pacstrap /mnt base linux-firmware <KERNEL> <MICROCODE> <EDITOR> <MISC_PKGS>
   

   Whereas, …

   • <KERNEL> means the Linux kernel of your choice
   • <MICROCODE> means the microcode for your platform
   • <EDITOR> stands for the text editor of your choice
   • <MISC_PKGS> represents further packages that might be needed. Some file systems can require additional tools - if you use Btrfs for your root partition, the package btrfs-progs is required, for example.

3. Go forward with the installation and configuration of your system. Finally, install and configure the boot loader.

   Remain in the chroot environment and do not reboot yet!

4. Adjust /etc/pacman.conf:

   • (Optional, but this makes the installation faster) Enable parallel download of packages by removing the comment sign from the line

       #ParallelDownloads = 5
     

   • Make the Archi3 Linux package repository known to pacman by adding the following lines at the end of the file:

       [archi3linux]  
       SigLevel = Optional TrustAll  
       Server = https://archi3linux.org/repo/$arch  
     

5. Update the system and install Archi3 Linux by executing

    $ pacman -Syu archi3linux
   

6. Create an (admin) user and set a password for the new user:

    $ useradd -mU -s /usr/bin/zsh -G wheel,uucp,sys,users <USER>
    $ passwd <USER>
   

7. Exit the chroot environment, unmount /mnt and reboot.

8. The i3-config-wizard starts upon first login of the new user asks you to make some basic decisions as described here.

9. Have fun with your system!

1. Choose the correct installation guide for the AArch64 platform for your specific device from archlinuxarm.org. This one is for the Raspberry Pi 4, for example.

2. Follow the instructions of the installation guide until the end (the RPi4 guide contains a section for ARMv7 and another one for AArch64 - go for the latter).

3. Execute the following steps from the standard guide (the examples below are for a German system, please adjust that according to your needs):

   • Set the host name:

       $ echo <YOUR-HOSTNAME> > /etc/hostname
     

   • Set locale:

       $ echo LANG=de_DE.UTF-8 > /etc/locale.conf
     

     Uncomment the following rows of /etc/locale.gen:

       #de_DE.UTF-8 UTF-8
       #de_DE ISO-8859-1
       #de_DE@euro ISO-8859-15
     

     Generate locale:

       $ locale-gen
     

   • Set keyboard layout and font:

       $ echo KEYMAP=de-latin1 > /etc/vconsole.conf
       $ echo FONT=lat9w-16 >> /etc/vconsole.conf
     

   • Set time zone:

       $ ln -sf /usr/share/zoneinfo/Europe/Berlin /etc/localtime
     

   • Define hosts in /etc/hosts:

       #<ip-address>	<hostname.domain.org>	<hostname>
       127.0.0.1	<YOUR-HOSTNAME>.localdomain	<YOUR-HOSTNAME>
       ::1		localhost.localdomain	localhost
     

   • Set the root password:

       $ passwd
     

4. Adjust /etc/pacman.conf:

   • (Optional, but this makes the installation faster) Enable parallel download of packages by removing the comment sign from the line

       #ParallelDownloads = 5
     

   • Make the Archi3 Linux package repository known to pacman by adding the following lines at the end of the file:

       [archi3linux]  
       SigLevel = Optional TrustAll  
       Server = https://archi3linux.org/repo/$arch  
     

5. Update the system and install Archi3 Linux by executing

    $ pacman -Syu archi3linux
   

6. Create an (admin) user and set a password for the new user:

    $ useradd -mU -s /usr/bin/zsh -G wheel,uucp,sys,users <USER>
    $ passwd <USER>
   

7. Reboot the system

8. The i3-config-wizard starts upon first login of the new user and asks you to make some basic decisions as described here.

9. Have fun with your system!

The following table shows the software that is part of Archi3 Linux:

In some areas Archi3 Linux deviates from the i3 standard. Rofi is used as application launcher instead of dmenu, Polybar is used instead of i3bar and i3status.

Wherever possible, Archi3 Linux uses the standard i3 key bindings. However, there are also some minor modifications and enhancements:

The status bar is provided by Polybar. On the left side it shows the active desktops, on the right side (as depicted above) it shows …

1. the keyboard layout
2. the current core load (one bar per thread)
3. the percentage of used space of the root file system
4. the percentage of used memory
5. the available battery load (in case the computer has a battery)
6. the current volume (by clicking on the loudspeaker icon, pavucontrol opens and the volume settings can be adjusted)
7. an Arch Linux icon, indicating if there are updates available (by clicking on the icon - no matter whether it’s highlighted or greyed out - a window opens and the download and installation of updates is triggered)
8. date and time
9. the system tray with the current connections (network, bluetooth etc.)

The configuration files for the different tools are stored in the standard locations (in ~/.config/i3/config for i3, for example).

Rofi Scripts

The scripts for launching applications, switching windows and exiting the system are stored in ~/.config/rofi.

Configure Floating Windows in i3

You might want to have some pop-up windows be floating permanently. This can be achieved with the command for_window in the i3 configuration (see the i3 documentation). To determine the necessary window attributes (class, id, title etc.), the script i3-get-window-criteria can be used (see the i3 faq). The script is part of Archi3 Linux.

The status bar is not displayed

Open a terminal via $mod+Return and try to start polybar with the command polybar. If an error message appears that a certain version of libjsoncpp.so is missing (libjsoncpp.so.22 for example), create a symbolic link for that version:

$ cd /usr/lib
$ ln -s libjsoncpp.so libjsoncpp.so.22

Restart your system, and the status bar should appear. This problem seems to be solved with more recent versions of polybar (> 3.5.0).

Some or all graphical symbols are not displayed in the status bar

For many symbols, Material Design Icons are used. It seems that sometimes for some of these symbols their code is changed. Then they cannot be displayed anymore in the status bar. To solve this, go to the Material Design Icons website to the “Cheatsheet” and copy the corresponding icons to the polybar configuration files ~.config/polybar/config (for most of the symbols) and/or ~.config/polybar/arch-updates.sh (for the Arch Linux symbol). Restart your system, and all symbols should appear.
