+## UWSM

+- [Universal Wayland Session Manager](https://github.com/Vladimir-csp/uwsm) 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.
+
+```sh
+yay -S uwsm
+```
+
+{{% /details %}}
+
+{{% details title="Nix/NixOS" closed="true" %}}
+
+```nix
+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](https://search.nixos.org/options?channel=unstable&show=programs.uwsm.enable&from=0&size=50&sort=relevance&type=packages&query=uwsm).
+
+{{< callout >}}
+
+If you use the [Home Manager module](../../Nix/Hyprland-on-Home-Manager), make sure to disable the systemd integration, as it conflicts with uwsm.

+Pay attention to the warnings in [Environment variables](../../Environment-variables#xdg-specifications) and [Dispatchers](../../Dispatchers) sections.

+
+### 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](https://github.com/Vladimir-csp/uwsm#3-applications-and-slices) 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.
