+#+title: Wayland
+
+Install [[https://wiki.archlinux.org/title/wayland][wayland]]: ~wayland~, ~xorg-xwayland~
+
+* Login Manager
+
+The login manager is not managed by this configuration but mentioned here since
+it interacts with the desktop environment. For ~hyprland~, ~sddm~ is
+recommended.
+
+- ~sddm~: Enable ~sddm.service~
+
+  A note about themes: The themes must be placed in ~/usr/share/sddm/themes~.
+  Then in ~/etc/sddm.conf~, enable the relevant theme. By default the breeze
+  theme comes with ~plasma-workspace~ which is very bloated to install, so
+  consider some of the alternative themes.
+
+* Fonts
+
+- ~otf-font-awesome~: Needed for ~waybar~ to render icons
+- Noto Sans/Serif: System font
+
+* Status Bar and Tray
+
+- ~waybar~: Status bar, use ~waybar-hyprland-git~ AUR repo to enable clicking!
+- ~eww-wayland~: Another status bar, requires ~socat~ to listen for hyprland events.
+
+* Sway
+
+This is one choice of a compositor.
+
+- ~swayfx~: Window manager
+- ~python-i3ipc~: Enables inactive window opacity scripts
+
+** Wallpaper
+Use ~multibg-sway~, which assigns a different wallpaper to each workspace and
+does not crash. The wallpapers directory ~~/.config/sway/wallpapers~ needs to be setup in this way:
+#+begin_src
+wallpapers
+    ├─ eDP-1
+    │    ├─ _default.jpg
+    │    ├─ 1.jpg
+    │    ├─ 2.png
+    │    └─ browser.jpg
+    └─ HDMI-A-1
+         ├─ 1.jpg
+         └─ 3.png
+#+end_src
+where the output information can be obtained from ~swaymsg -t get_outputs~.
+
+Supposedly does not work with ~hypr~.
+
+* Hyprland
+
+This is another choice of a compositor.
+
+Note: Setup does not work with NVIDIA GPU without some tweaks.
+
+- [[https://wiki.archlinux.org/title/Hyprland][hyprland]]: window manager
+  Until [[https://github.com/elkowar/eww/issues/111][tray support]] has been added to ~eww~ in a stable manner, tray will be handled with waybar.
+- ~hyprpaper~: Wallpaper engine
+
+  The command to set a wallpaper:
+ ~hyprctl hyprpaper wallpaper "$DISPLAY,$FILE"~
+The command for changing keyboard layouts is handled by ~fcitx5~.
+
+* Utilities
+
+- [[https://github.com/Horus645/swww][swww]]: Alternate wallpaper engine
+
+  Note that ~~/.config/hypr/wallpapers~ must have jpeg files ~{1..8}.jpg~. A
+  handy command can be used crop and resize images:
+  #+begin_src bash
+convert $IN \
+	-resize 3840x2160^ \
+	-gravity center \
+	-extent 3840x2160 \
+	$OUT
+  #+end_src
+- ~swaync~: Notification server

+- ~grimblast~: Screenshot engine
+- ~dolphin~: File explorer
+- ~swaylock-effects~: A simple lockscreen
+- ~wl-clipboard~: Provides copying
