### 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
doasaddgroup 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 ### Installing Waybar

riverctl spawn "waybar" 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'
```
## 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 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`.
### 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)

### 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`.
