 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

+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

+### HiDPI

+```
+doas apk add kanshi
+mkdir .config/kanshi
+```

+and create `.config/kanshi/config` with the following:
+```
+profile {

+}
+```
+
+(`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'
+```

+## Other software
+
+### 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 _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`.

+### Clipboard?

+### Firefox

+```
+doas apk add firefox

+```
+go to `about:support` and make sure that Window Protocol is wayland, not xwayland.

 ## 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.

+### WiFi

+At the moment Linux kernel does not support TODO Qualcomm WiFi module installed in this laptop.

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