Arch Install Part 2: Post-Install

This is a follow-up of the previous post.

Once we have our system up and running, we can start adding stuff

Install yay (aur helper)

git clone https://aur.archlinux.org/yay-bin.git && cd yay-bin && makepkg -si

Add Chaotic Aur Binary Repo

# Solve problem with gnupg not using systemd-resolved
sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
# Add chaotic repo keys 
# https://aur.chaotic.cx/docs
sudo pacman-key --recv-key 3056513887B78AEB --keyserver keyserver.ubuntu.com
sudo pacman-key --lsign-key 3056513887B78AEB
sudo pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-keyring.pkg.tar.zst'
sudo pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-mirrorlist.pkg.tar.zst'
# Add repos
su
cat >> /etc/pacman.conf <<EOF
[proaudio]
Server = https://arch.osamc.de/$repo/$arch

[chaotic-aur]
Include = /etc/pacman.d/chaotic-mirrorlist
EOF

Install some apps

From here, and that's the beauty of Arch, we can install whatever we need, and nothing else:

• CLI Apps: bash-completion, manb-pages, vim, btop, base-devel, git..
• Sound: pipewire pipewire-pulse pipewire-zeroconf alsa-utils pulsemixer..
• Bluetooth and Wifi: bluez bluez-utils bluetui impala..
• Video acceleration: vdpauinfo intel-media-driver intel-gpu-tools (for Intel GPUs)
• Display Manager: ly, greetd-tui, greetd-regreet..
• Wayland compositors: sway, labwc, wayfire, hyprland, niri ...or any desktop environment
• Wayland utilites: foot, waybar, wofi, fuzzel, mako, wlsunset, swaylock, swayidle..
• Desktop portals: xdg-desktop-portal-wlr xdg-desktop-portal-gtk..
• Desktop apps: thunar, mpv, librewolf, libreoffice..

Permissions

A part from sudo, you can also allow privileges using the polkit daemon, allowing certain users to reboot o shutdown the system without using sudo.

sudo cat > /etc/polkit-1/rules.d/49-nopasswd_global.rules << EOF
/* Allow members of the wheel group to execute any actions
 * without password authentication, similar to "sudo NOPASSWD:"
 */
polkit.addRule(function(action, subject) {
    if (subject.isInGroup("wheel")) {
        return polkit.Result.YES;
    }
});
EOF
