UWSM
- Universal Wayland Session Manager is a recommended way to start Hyprland session on systemd distros. uwsm wraps standalone Wayland compositors into a set of Systemd units and provides robust session management including environment, XDG autostart support, bi-directional binding with login session, and clean shutdown.
Installation
{{% details title="Arch" closed="true" %}}
uwsm is available in AUR. You can install it either with an AUR helper, or build PKGBUILD manually. Here's an example for yay.
yay -S uwsm
{{% /details %}}
{{% details title="Nix/NixOS" closed="true" %}}
programs.uwsm = {
enable = true;
waylandCompositors.hyprland = {
binPath = "/run/current-system/sw/bin/Hyprland";
comment = "Hyprland session managed by uwsm";
prettyName = "Hyprland";
};
};
The above option generates a new desktop entry, hyprland-uwsm.desktop, which will be available in display managers.
For more info, read the option.

If you use the Home Manager module, make sure to disable the systemd integration, as it conflicts with uwsm.
wayland.windowManager.hyprland.systemd.enable = false;

For instructions for other distros and manual building, see building and installing section on the project's page.

Launching Hyprland with uwsm
{{< callout type=info >}}
Pay attention to the warnings in Environment variables, Multi-GPU and Dispatchers sections.
{{< /callout >}}
In tty
To launch Hyprland with uwsm, add this code in your shell profile.
if uwsm check may-start && uwsm select; then
exec systemd-cat -t uwsm_start uwsm start default
fi
This will bring uwsm compositor selection menu after you log in tty1. Choose Hyprland entry and you're good to go.
If you want to bypass compositor selection menu and launch Hyprland directly, use this code in your shell profile, instead.
if uwsm check may-start; then
exec uwsm start hyprland.desktop
fi
Using a display manager
If you use a display manager, choose hyprland (uwsm-managed) entry in a display manager selection menu.
Launching applications inside session
The concept of a session managed by Systemd implies also running applications as units. Uwsm provides a helper to do it.
Prefix application startup commands with uwsm app --. It also supports launching Desktop Entries by IDs or paths. See man uwsm or uwsm app --help.
Examples for autostart and bind entries:
exec-once = uwsm app -- mycommand --arg1 --arg2
bind = SUPER, E, exec, uwsm app -- pcmanfm-qt.desktop
Running applications as child processes inside compositor's unit is discouraged.
