In /etc/apk/repositories, comment out 3.16, uncomment edge (main, community, testing), since some of the packages we're going to install (river, element-desktop) only exist in testing.

Then

doas apk update
doas apk upgrade

Usable editor by default (not vi)

doas apk add micro
echo "export EDITOR=micro" >>.profile
echo "permit setenv { EDITOR=\$EDITOR } nopass :wheel as root" | tee -a /etc/doas.d/doas.conf

Installing river

doas apk add eudev
doas setup-udev
doas apk add mesa-dri-gallium mesa-va-gallium
doas apk add river river-doc mandoc
doas apk add adwaita-icon-theme foot ttf-dejavu
doas rc-update add seatd
doas rc-service seatd start
doas addgroup YOURUSER audio
doas addgroup YOURUSER input
doas addgroup YOURUSER seat
doas addgroup YOURUSER video
doas addgroup YOURUSER wheel
install -Dm0755 /usr/share/doc/river/examples/init -t ~/.config/river

Also:

doas apk add xwayland

because the latest river in testing is built in a way that requires xwayland.

Try to run with

XDG_RUNTIME_DIR=/tmp river

You should see the blue screen of river. Try to open terminal with Win+Shift+Enter. Try to exit with Win+Shift+E.

To enter username/password in GUI, get to river after that, and get back to logon screen after exiting river:

doas apk add elogind polkit-elogind
doas rc-update add elogind
doas rc-service elogind start
doas apk add greetd greetd-gtkgreet cage
doas addgroup greetd video
doas rc-update add greetd

change /etc/greetd/config.toml

command = "cage -s -- gtkgreet"

and create /etc/greetd/environments with a single line river

and reboot.

I didn't find a way to make cage+gtkgreet handle HiDPI, the text is very tiny.

An alternative is agreety, but for some reason it seems that both greeter and standard linux login prompt run at the same time on the same terminal, making it impossible to actually login.

Installing Waybar

doas apk add waybar font-roboto

and add startup section at the end of river init file (~/.config/river/init):

# startup
riverctl spawn "waybar"

For time to work,

doas apk add tzdata

For icons to work,

doas apk add font-roboto

(do not add font-awesome, for some reason it looks awful, kerning is terrible, and the text is all-caps in waybar with it)

HiDPI

doas apk add kanshi
mkdir .config/kanshi

and create .config/kanshi/config with the following:

profile {
	output eDP-1 enable scale 2.5
}

(eDP-1 identifier was obtained by installing sway, running sway (by adding it to /etc/greetd/environments, and in terminal inside sway executing swaymsg -t get_outputs).

HiDPI - cursors

And in order to have decently sized mouse cursors instead of the tiniest ones, add the following line to the top of .config/river/init:

riverctl xcursor-theme Adwaita 24

This will only affect river itself, the cursor will stay tiny in waybar and firefox and maybe other applications. To solve this:

doas apk add gsettings-desktop-schemas
gsettings set org.gnome.desktop.interface cursor-theme 'Adwaita'

Environment

In order to not have to create wrapper scripts for all apps:

Create /usr/local/bin/inga-river (and later chmod +x /usr/local/bin/inga-river) with the following (found in google):

#!/bin/sh

export GDK_BACKEND=wayland,x11
export MOZ_ENABLE_WAYLAND=1
export CLUTTER_BACKEND=wayland
export QT_QPA_PLATFORM=wayland-egl
export ECORE_EVAS_ENGINE=wayland-egl
export ELM_ENGINE=wayland_egl
export SDL_VIDEODRIVER=wayland
export _JAVA_AWT_WM_NONREPARENTING=1
export NO_AT_BRIDGE=1
export BEMENU_BACKEND=wayland

river $@

and replace river with inga-river in /etc/greetd/environments.

Launcher

doas apk add bemenu, and then add this line into your river config:

riverctl map normal Super R spawn 'pidof bemenu-run || bemenu-run -i -n'

Screenshots

doas apk add wayshot, then add this line to river config:

riverctl map normal None Print spawn 'wayshot --stdout | wl-copy'

Clipboard

Works by default, use Ctrl+Shift+C and Ctrl+Shift+V in foot

Emoji keyboard

doas apk add rofi-emoji rofi-emoji-wayland wtype and add this line to your river config

riverctl map normal Super period spawn 'rofi -modi emoji -show emoji'

(For some reason it broke after reboot and only copies things to clipboard, even though wtype continues to work without any problems)

Notifications

doas apk add dunst
dunst &
dunstify test

You should get a notification with the text "test".

Then add riverctl spawn "dunst" to the startup section of your river config.

TODO: wired-notify instead of dunst (currently not packaged for alpine)

Other software

Firefox

doas apk add firefox
firefox

go to about:support and make sure that Window Protocol is wayland, not xwayland. (it should be wayland because MOZ_ENABLE_WAYLAND is set to 1 by inga-river)

For some reason, while sound in general works fine in firefox (after following the steps from Hardware section), in WebRTC pages there is crackling much louder than the actual voices, making it unusable for voice/video calls/meetings.

Chrome

doas apk add chromium

It should also be wayland by default, but you can check it by doas apk add xeyes && xeyes.

In order for screen sharing to work, go to chrome://flags/#enable-webrtc-pipewire-capturer and enable it. Note though that every time you screenshare, there will be two promps from xdg-desktop-portal, one for picking a source, and another for actually sharing.

Git

doas apk install git
git config --global credential.helper --store

doas apk install telegram-desktop

Element

doas apk install element-desktop

Hardware

Sleep

With default settings, laptop goes to sleep after some idle period. When it wakes up, the root fs is readonly, meaning that I have to restart the laptop.

Adding acpiphp.disable=1 and pcie_aspm=off to grub config does not solve the issue.

Disabling S0ix in UEFI only made things worse: even though cat /sys/power/mem_sleep reported that S3 (deep) is default, after system goes to sleep it is impossible to wake it up, it does not react to key or power button presses.

What did solve the issue was:

reenable S0ix in BIOS,
doas apk add linux-firmware-amdgpu,
editing GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub to add the following options: acpiphp.disable=1 pcie_aspm=off acpi_osi='Windows 2020' iommu=soft.

Now after waking up (after being suspended with doas pm-suspend from pm-utils package) root fs is still readwrite. But sometimes network disappears after wakeup.

For suspend on lid close and unsuspend on open, follow https://wiki.alpinelinux.org/wiki/Suspend_on_LID_close :

doas mkdir -p /etc/acpi/LID
doas micro /etc/acpi/LID/00000080

should have the following content

#!/bin/sh
exec pm-suspend

and then

doas chmod +x /etc/acpi/LID/00000080
doas rc-service acpid restart

WiFi

At the moment Linux kernel does not support Qualcomm NFA725.

Otherwise, alpine wiki describes how to configure WiFi using iwd.

Backlight

doas apk add light
doas micro /etc/udev/rules.d/backlight.rules

add the following lines into backlight.rules to make it possible for all users in video group (not just superusers) to control backlight:

ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chgrp video /sys/class/backlight/%k/brightness"
ACTION=="add", SUBSYSTEM=="backlight", KERNEL=="amdgpu_bl0", RUN+="/bin/chmod g+w /sys/class/backlight/%k/brightness"

and then

doas rc-service udev restart

Backlight control with Fn+F5/F6 should work now.

(amdgpu_bl0 is specific for this laptop; value for others can be obtained from /sys/class/backlight/)

Trackpoint

Disregard this:

find /sys/devices/platform/i8042/ -name name | xargs grep -Fl TrackPoint
to find which serio corresponds to trackpoint, then
echo 70 | doas tee /sys/devices/platform/i8042/serio1/sensitivity
for reasonably low sensitivity (does not persist; for persistence TODO separate udev rule).

Instead of configuring sensitivity, it's probably better to configure pointer speed in river.

Find your trackpoint with riverctl list-inputs | grep -i trackpoint, it will look like 2:10:TPPS/2_Elan_TrackPoint.

Then add the following to your river config:

riverctl input 2:10:TPPS/2_Elan_TrackPoint accel-profile adaptive
riverctl input 2:10:TPPS/2_Elan_TrackPoint pointer-accel -0.5

Sound

Based on https://wiki.alpinelinux.org/wiki/PipeWire

doas apk add dbus dbus-openrc
doas rc-service dbus start
doas apk add pipewire wireplumber rtkit alsa-utils pipewire-alsa
doas addgroup YOURUSER rtkit
doas addgroup root audio
alsamixer

In alsamixer, use F6 to find the target sound card (most likely 0 is HDMI and 1 is ordinary). Remember its number, and in /usr/share/alsa/alsa.conf, replace defaults.ctl.card and defaults.pcm.card with the target number.

In /usr/local/bin/inga-river, replace river $@ with dbus-run-session -- river $@, relogin (Ctrl+Shift+E).

Then

doas rc-service alsa start
doas rc-update add alsa
/usr/libexec/pipewire-launcher

Make sure that everything works (with wpctl status, pw-cat -p YOURFILE.flac or just opening YouTube in FF).

Then make pipewire start automatically: in river config, add another startup line:

riverctl spawn "/usr/libexec/pipewire-launcher"

Control microphone and volume with alsamixer. And change the handlers for XF86Audio (adding -repeat and replacing the spawned command):

riverctl map -repeat $mode None XF86AudioRaiseVolume spawn 'amixer set "Master" 5%+'
riverctl map -repeat $mode None XF86AudioLowerVolume spawn 'amixer set "Master" 5%-'
riverctl map $mode None XF86AudioMute spawn 'amixer set "Master" toggle'

Note that the internal microphone does not work and is not detected by pipewire. Only external microphones work.

Mic in browser didn't work, but then it started to work at some point, without me seemingly changing anything.

Mic mute button

Create /etc/acpi/events/lenovo-mutemic with the following content:

event=button/micmute MICMUTE 00000080 00000000 K
action=amixer --card 1 set 'Capture' toggle

where card number is the one obtained in previous section; and event could be determined by running acpi_listen and pressing mic button.

Then, after doas rc-service acpid restart, mic button should control internal mic capture in alsa and switch internal mic led on and off.

Webcam

Should work after following the steps for "Audio".

Can be tested in https://webrtc.github.io/test-pages

Additional

doas apk add xdg-desktop-portal xdg-desktop-portal-wlr

and DO NOT add to your river config

riverctl spawn "/usr/libexec/xdg-desktop-portal-wlr"

(for some reason it does not work when spawned by river during init (process is running, but screensharing attempts lead to nothing), but /usr/libexec/xdg-desktop-portal-wlr & from shell works fine)

Add the following lines to river config (before the last exec line):

riverctl float-filter-add title "Firefox — Sharing Indicator"
riverctl float-filter-add title 'Firefox — Sharing Indicator'

(TODO: check which kind of quotes works)

Development (containers)

Unprivileged LXC with routing

(based partially on https://linuxcontainers.org/lxc/getting-started and https://wiki.alpinelinux.org/wiki/LXC)

Networking (host)

(assuming that your internet-connected interface is eth0, and that you want to use 10.157.1.0/24 subnet for the container)

Add the following to /etc/network/interfaces:

auto br0
iface br0 inet static
	bridge-ports dummy0
	bridge-stp 0
	address 10.157.1.1
	netmask 255.255.255.0

and do

doas apk add bridge
doas modprobe dummy
echo dummy | doas tee -a /etc/modules
echo 1 | doas tee -a /proc/sys/net/ipv4/ip_forward
doas apk add iptables
doas rc-update add iptables
doas iptables --table nat --append POSTROUTING --out-interface eth0 -j MASQUERADE
doas iptables --append FORWARD --in-interface br0 -j ACCEPT
doas /etc/init.d/iptables save

Containers support

doas apk add lxc lxcfs lxc-download xz gnupg
echo "$(id -un):10000000:5000000" | doas tee -a /etc/subuid
echo "$(id -un):10000000:5000000 | doas tee -a /etc/subgid
echo "$(id -un) veth br0 10" | doas tee -a /etc/lxc/lxc-usernet
doas rc-update add cgroups lxc lxcfs dbus

Creating container

Create `~/.config/lxc/CONTAINERNAME.conf" with the following content:

lxc.net.0.type = veth
lxc.net.0.flags = up
lxc.net.0.link = br0
lxc.net.0.ipv4.address = 10.157.1.2/24 10.157.1.255
lxc.net.0.ipv4.gateway = 10.157.1.1
lxc.net.0.veth.pair = veth-if-0
# this is not a mistype, 500K should be enough for all your nesting needs, and 5M in /etc/subuid should be enough if you want to create any other containers
lxc.idmap = u 0 10000000 500000
lxc.idmap = g 0 10000000 500000

lxc.include = /usr/share/lxc/config/nesting.conf
lxc.apparmor.allow_nesting = 1
lxc.seccomp.allow_nesting = 1
lxc.mount.auto = proc sys cgroup:rw:force

Then:

lxc-create -n CONTAINERNAME -f .config/lxc/CONTAINERNAME.conf -t download
# pick OS (alpine/edge/amd64 in my case)
lxc-start -n CONTAINERNAME # make sure it does not produce any errors
lxc-attach --clear-env -n CONTAINERNAME

You'll get into a container root console.

(but still inside this container apk cgroups start will produce errors and mount everything in /sys/fs/cgroups except for openrc as nobody:nobody, and won't mount openrc at all, and nested containers won't work.)

Networking (container)

In container root console, check if network is up with ifconfig. If there are no IPv4 address for eth0, you'll have to configure it manually, by editing /etc/network/interfaces. The easiest way to do it is by

doas micro ~/.local/share/lxc/CONTAINERNAME/rootfs/etc/network/interfaces`

on the host.

In the end the file should look like

auto eth0
iface eth0 inet static
    address 10.157.1.2
    netmask 255.255.255.0
    gateway 10.157.1.1
hostname $(hostname)

Then rc-service networking restart, and check ifconfig. If everything is right, there should be an ipv4 address in ifconfig, and ping 10.157.1.1 inside container and ping 10.157.1.2 inside host should work.

ping 8.8.8.8 inside container should work too, thanks for routing.

Now, if ping google.com does not work, configure DNS in container:

echo nameserver 8.8.8.8 >> /etc/resolv.conf
echo nameserver 8.8.4.4 >> /etc/resolv.conf

(or add them using micro on the host, as you did for interfaces)

Make sure ping 8.8.8.8 works. APK should work too: apk add micro neofetch

Creating an user inside container

In container root shell:

adduser -g USERNAME USERNAME
adduser USERNAME wheel
echo "permit persist :wheel" >> /etc/doas.d/doas.conf

Now exit root shell (just with exit), and try lxc-console -n CONTAINERNAME. You should be able to log in using the new username and password. (To exit lxc console, use Ctrl+A, Q).

Alternatively: unprivileged LXC using LXD

Security notes

Note that with LXD, unprivileged containers run under root, which is not supposed to give them any extra privileges (source: https://discuss.linuxcontainers.org/t/privileged-and-unprivileged-containers/12060/2), but this implies that:

Containers can only be managed with LXD using root access. Which means either doas for every command (including connecting to the container shell), or adding your user to the lxd group which will have access to LXD daemon, which will effectively give your user passwordless sudo (since access to LXD daemon can trivially be used to gain root privileges), so that any process running under your user can trivially gain root privileges on the host (which is for some reason not considered by LXD maintainers to be a problem).

DO NOT add your user to the lxd group, and DO NOT uncomment --group lxd in /etc/conf.d/lxd

Instead the secure way of doing things would probably be to only use lxd as a root, and connect to the container using ssh.

Containers support

As simple as

apk add lxd lxd-client lxcfs dbus
rc-update add lxc
rc-update add lxd
rc-update add lxcfs
rc-update add dbus
doas reboot

Networking with routing should work automatically.

Creating container

doas lxc launch images:alpine/edge -c security.nesting=true -c security.privileged=false test-alpine-container
doas lxc exec test-alpine-container -- /bin/ash

Networking should work inside of container.

OpenSSH

With password-based auth (not recommended): in container (from root, lxc-attach/lxc exec)

apk add openssh
rc-update add sshd
rc-service sshd start

Check IP of container with ifconfig, and then on host,

doas apk add openssh-client
ssh CONTAINER_IP

With keys-based auth: TODO

Webdev

Accessing dev sites running inside container

In container: doas apk add squid, and edit /etc/squid/squid/conf accordingly (most likely you'll only need to change local network definition to match the subnet shared between the host and the container).

Then:

doas rc-update add squid
doas rc-service squid start

(Note that squid requires devfs service to be running).

In host, create new FF profile (about:profiles) for that purpose, and configure it to use squid proxy running inside of container.

VS Code Remote (does not work)

Connects to host successfully, but does not let to do anything (not even to open a folder): produces "Connection error: Client refused: version mismatch" error, presumably due to code-oss being used on VS client (system host) and vscodium being used on host (LXC container). (Only code-oss is present in alpine packages, and only vscodium has remote-host binaries).

Steps to get to that stage (one of the sources: https://github.com/microsoft/vscode-remote-release/issues/6347), assuming that you already have keyring and key-based SSH auth (with non-RSA key) configured:

In container:

doas apk add gcompat libstdc++ curl bash git procps

and enable AllowTcpForwarding and PermitTunnel in /etc/ssh/sshd_config.

In host:

doas apk add code-oss

Edit /usr/lib/code-oss/resources/app/package.json: at the root level, add "release": "22245", (replace 22245 with an actual value for your version from https://github.com/VSCodium/vscodium/releases).

Edit /usr/lib/code-oss/resources/app/package.json: at the root level, add "commit": "COMMIT_ID", "quality": "stable", (replace COMMIT_ID with an actual commit id from the same source). Replace "serverApplicationName" with "codium-server", and "serverDataFolderName" with ".vscodium-server".

Run code-oss, add "Open Remote - SSH" extension by jeanp413, exit.

Add "enable-proposed-api": ["jeanp413.open-remote-ssh"] at the root level of ~/.vscode-oss/argv.json.

Run code-oss again, you'll get remote button under the marketplace button. Go there, add your host, right-click it, connect. Connection should be successful, and you should see "connected to remote" on Code OSS main screen. But "Open file" / "Open folder" will still list local directory structure, and in debug output for "Window" there will be an error message about "version mismatch".

Docker

For container terminal apps to be usable:

doas apk add ncurses-terminfo

(inside LXC)

TODO once nesting in LXC works (reference: https://discuss.linuxcontainers.org/t/lxc-on-alpine-host-sys-fs-cgroup-is-not-mounted-into-unprivileged-alpine-guest/15026/1)

(inside LXD)

As simple as

doas apk add docker
doas rc-update docker start
doas docker run hello-world

in the guest.

For networked docker containers, doas lxc config edit CONTAINERNAME, add linux.kernel_modules: br_netfilter to the config: section, and restart container (doas lxc restart CONTAINERNAME).
