* Isn't Alpine Linux for Servers?

This is a question I see a lot when people are presented with an example
of Alpine Linux running as a desktop OS.

While Alpine is small, fast, and minimal, that doesn't stop it from
functioning at a productive level for desktop users.

This post is documentation of how I installed and modified Alpine Linux
to become my daily desktop OS.

* Installation

Note that I cover the installation of Alpine Linux in my other post, so
I won't repeat it here: [[../alpine-linux/][Alpine Linux: My New Server
OS]].

Basically, get a bootable USB or whatever you prefer with Alpine on it,
boot the ISO, and run the setup script.

#+begin_src sh
setup-alpine
#+end_src

Once you have gone through all the options and installer finishes
without errors, reboot.

#+begin_src sh
reboot
#+end_src

* Initial Setup

Once Alpine is installed and the machine has rebooted, login is as root
initially or =su= to root once you log in as your user. From here, you
should start by updating and upgrading the system in case the ISO was
not fully up-to-date.

#+begin_src sh
# Update and upgrade system
apk -U update && apk -U upgrade

# Add an editor so we can enable the community repository
apk add nano
#+end_src

You need to uncomment the =community= repository for your version of
Alpine Linux.

For v3.17, the =repositories= file should look like this:

#+begin_src sh
nano /etc/apk/repositories
#+end_src

#+begin_src conf
#/media/sda/apks
http://mirrors.gigenet.com/alpinelinux/v3.17/main
http://mirrors.gigenet.com/alpinelinux/v3.17/community
#http://mirrors.gigenet.com/alpinelinux/edge/main
#http://mirrors.gigenet.com/alpinelinux/edge/community
#http://mirrors.gigenet.com/alpinelinux/edge/testing
#+end_src

#+begin_src sh
# Add the rest of your packages
apk add linux-firmware iwd doas git curl wget

# Add yourself to the wheel group so you can use the doas command
adduser $USER wheel
#+end_src

* Window Manager (Desktop)

The [[https://wiki.alpinelinux.org/wiki/Sway][Sway installation guide]]
has everything you need to get Sway working on Alpine.

However, I'll include a brief list of the commands I ran and their
purpose for posterity here.

#+begin_src sh
# Add eudev and set it up
apk add eudev
setup-devd udev

# Since I have Radeon graphics, I need the following packages
apk add mesa-dri-gallium mesa-va-gallium

# Add user to applicable groups
adduser $USER input
adduser $USER video

# Add a font package
apk add ttf-dejavu

# Add the seatd daemon
apk add seatd
rc-update add seatd
rc-service seatd start

# Add user to seat group
adduser $USER seat

# Add elogind
apk add elogind polkit-elogind
rc-update add elogind
rc-service elogind start

# Finally, add sway and dependencies
apk add sway sway-doc
apk add                \ # Install optional dependencies:
    xwayland             \ # recommended for compatibility reasons
    foot                 \ # default terminal emulator
    bemenu               \ # wayland menu
    swaylock swaylockd   \ # lockscreen tool
    swaybg               \ # wallpaper daemon
    swayidle               # idle management (DPMS) daemon
#+end_src

Once you have the packages installed and set-up, you need to export the
=XDG_RUNTIME_DIR= upon login. To do this, edit your =.profile= file.

If you use another shell, such as =zsh=, you need to edit that shell's
profile (e.g., =~/.zprofile=)!

#+begin_src sh
nano ~/.profile
#+end_src

Within the file, paste this:

#+begin_src sh
if test -z "${XDG_RUNTIME_DIR}"; then
  export XDG_RUNTIME_DIR=/tmp/$(id -u)-runtime-dir
  if ! test -d "${XDG_RUNTIME_DIR}"; then
    mkdir "${XDG_RUNTIME_DIR}"
    chmod 0700 "${XDG_RUNTIME_DIR}"
  fi
fi
#+end_src

Once that's complete, you can launch Sway manually.

#+begin_src sh
dbus-run-session -- sway
#+end_src

** Personal Touches

I also added the following packages, per my personal preferences and
situation.

#+begin_src sh
doas apk add brightnessctl   \ # Brightness controller
             zsh             \ # Shell
             firefox         \ # Browser
             syncthing       \ # File sync service
             wireguard-tools \ # Wireguard VPN
             gomuks          \ # CLI Matrix client
             neomutt         \ # CLI email client
             thunderbird     \ # GUI email client
             gnupg             # GPG key manager
#+end_src

From here, I use my Syncthing storage to pull all the configuration files I
stored from prior desktops, such as my [[https://github.com/ccleberg/dotfiles][dotfiles]].

* Resolving Issues

** WiFi Issues

I initially tried to set up my Wi-Fi the standard way with =iwd=, but it
didn't work.

Here is what I initially tried (I did all of this as =root=):

#+begin_src sh
apk add iwd
rc-service iwd start
iwctl station wlan0 connect <SSID> # This will prompt for the password
rc-update add iwd boot && rc-update add dbus boot
#+end_src

Then, I added the Wi-Fi entry to the bottom of the networking interface
file:

#+begin_src sh
nano /etc/network/interfaces
#+end_src

#+begin_src conf
auto wlan0
iface wlan0 inet dhcp
#+end_src

Finally, restart the networking service:

#+begin_src sh
rc-service networking restart
#+end_src

My Wi-Fi interface would receive an IP address from the router, but it
could not ping anything in the network. To solve the Wi-Fi issues, I
originally upgraded to Alpine's =edge= repositories, which was
unnecessary.

Really, the solution was to enable the =NameResolvingService=resolvconf=
in =/etc/iwd/main.conf=.

#+begin_src sh
doas nano /etc/iwd/main.conf
#+end_src

#+begin_src conf
[Network]

NameResolvingService=resolvconf
#+end_src

Once I finished this process, my Wi-Fi is working flawlessly.

** Sound Issues

Same as with the Wi-Fi, I had no sound and could not control the
mute/unmute or volume buttons on my laptop.

To resolve this, I installed
[[https://wiki.alpinelinux.org/wiki/PipeWire][pipewire]].

#+begin_src sh
# Add your user to the following groups
addgroup $USER audio
addgroup $USER video

# Install pipewire and other useful packages
apk add pipewire wireplumber pipewire-pulse pipewire-jack pipewire-alsa
#+end_src

Finally, I needed to add =/usr/libexec/pipewire-launcher= to my
=.config/sway/config= file so that Pipewire would run every time I
launched sway.

#+begin_src sh
nano ~/.config/sway/config
#+end_src

#+begin_src conf
# Run pipewire audio server
exec /usr/libexec/pipewire-launcher

# Example audio button controls
bindsym XF86AudioRaiseVolume exec --no-startup-id pactl set-sink-volume @DEFAULT_SINK@ +5%
bindsym XF86AudioLowerVolume exec --no-startup-id pactl set-sink-volume @DEFAULT_SINK@ -5%
bindsym XF86AudioMute exec --no-startup-id pactl set-sink-mute @DEFAULT_SINK@ toggle
bindsym XF86AudioMicMute exec --no-startup-id pactl set-source-mute @DEFAULT_SOURCE@ toggle
#+end_src

Note that I do not use bluetooth or screen sharing, so I won't cover
those options in this post.

Other than these issues, I have a working Alpine desktop. No other
complaints thus far!
