This page documents software that is critical / very important to have running for a smooth
Wayland / Hyprland experience.
DEs like KDE / Gnome will do this automatically, Hyprland will not (because you might want to use something else)
### A notification daemon
_Starting method:_ most likely manual (`exec-once`)
Many apps (e.g. Discord) may freeze without one running.
Use e.g. `dunst`, `mako`, `swaync`, etc.
### Pipewire
_Starting method:_ Automatic on Systemd, manual otherwise
Pipewire is not necessarily required, but screensharing will not work without it.
Install `pipewire` and `wireplumber` (**not** `pipewire-media-session`)
#### Non-systemd distros
Since here is no truly standardized way (outside of systemd) to load PipeWire when starting
a graphical shell[^1] non-systemd distros like Gentoo or Artix provide a decicated launcher.
It can be usually found by running `whereis <distro>-pipewire-launcher`.
If such file does not exist on your install please refer to your distro's documentation for help.

### XDG Desktop Portal
_Starting method:_ Automatic on Systemd, manual otherwise
XDG Desktop Portal handles a lot of stuff for your desktop, like file pickers,
screensharing, etc.
See the [Hyprland Desktop Portal Page](../Hyprland-desktop-portal)
### Authentication Agent
_Starting method:_ manual (`exec-once`)
Authentication agents are the things that pop up a window asking you for a password whenever
an app wants to elevate its privileges.
Our recommendation is the KDE one. For arch, it's `polkit-kde-agent`.
You can autostart it with `exec-once=/usr/lib/polkit-kde-authentication-agent-1`.
On some distributions you might have to use a different path `/usr/libexec/polkit-kde-authentication-agent-1`.
On other distributions that use a more recent version, such as Gentoo, it may be necessary to use `exec-once=/usr/lib64/libexec/polkit-kde-authentication-agent-1` instead.
### Qt Wayland Support
_Starting method:_ none (just a library)
Install `qt5-wayland` and `qt6-wayland`.
