My journey to get Alpine + Wayland + River to work on ThinkPad T14 G3 AMD (21CF004PGE)
Preparing hardware
Disable secure boot and fn-lock in bios (so that F-keys work as F-keys by default and require Fn for their secondary multimedia functions).
Installing Alpine
Follow https://wiki.alpinelinux.org/wiki/Installation
Note that you will need to use Rufus; Ventoy does not work on this laptop (hangs after choosing the image).
Postinstall
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
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.
Login manager
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
and add startup section at the end of river init file (~/.config/river/init
):
# startup
riverctl spawn "waybar"
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 'bemenu-run -i -n'
Other software
Clipboard?
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.
Telegram
doas apk install telegram-desktop
Element
doas apk install element-desktop
Hardware
Sleep
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.
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 nano /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
Disregar 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).
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
.
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.
Webcam
Should work after following the steps for "Audio".
Can be tested in https://webrtc.github.io/test-pages
Additional
Screen sharing
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)
Prevent firefox sharing indicator from taking the entire tile
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)
