# Hyprland session environment and desktop integration diagnosis

A command working in a terminal but failing from a desktop binding often indicates different environments. An active service with no working interface may be connected to the wrong graphical session. Separate startup source, environment and actual interface behaviour.

## Start with three questions

Which component failed? Who launched it? Which session does it connect to? Record the trigger and timestamp before reading its logs. Restarting everything first can remove useful evidence.

## Shell and user-service environments differ

`.zshrc` may add `~/.local/bin` to PATH, but the user service manager does not execute that file. Check terminal resolution:

```bash
command -v ghostty
printf '%s\n' "$PATH"
```

Compare relevant variables with `systemctl --user show-environment`; avoid publishing the complete environment.

For a custom session setup, import the required variables after the compositor creates them and before dependent services start:

```bash
systemctl --user import-environment WAYLAND_DISPLAY DISPLAY XDG_CURRENT_DESKTOP XDG_SESSION_TYPE HYPRLAND_INSTANCE_SIGNATURE
dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP XDG_SESSION_TYPE HYPRLAND_INSTANCE_SIGNATURE
```

Run these inside the correct graphical session. A remote shell without Wayland state cannot repair it by importing absent values. With distribution session management or UWSM, follow its lifecycle rather than layering unrelated scripts on top.

## Ordering and service lifetime

`After=` controls ordering without starting a dependency; `Wants=` requests one; `PartOf=` propagates stop/restart operations. They require a real session target and lifecycle owner.

This illustrative `doc-shell.service` assumes an existing, correctly managed `hyprland-session.target`, `/usr/bin/qs` and Caelestia installation:

```ini
[Unit]
Description=Example desktop shell
PartOf=hyprland-session.target
After=graphical-session-pre.target
ConditionEnvironment=WAYLAND_DISPLAY

[Service]
ExecStart=/usr/bin/qs -c caelestia -n
Restart=on-failure
RestartSec=2

[Install]
WantedBy=hyprland-session.target
```

Do not enable it alongside an existing shell service. `ConditionEnvironment` checks presence, not whether the Wayland socket is still alive. The session manager must stop its services when the session ends. [systemd session conventions](https://www.freedesktop.org/software/systemd/man/latest/systemd.special.html)

## Screen sharing and file selection

Applications use xdg-desktop-portal and selected backends for desktop interfaces. Installing a backend does not prove requests reach it.

Check actual service names for the distribution:

```bash
systemctl --user status xdg-desktop-portal.service xdg-desktop-portal-hyprland.service
journalctl --user -u xdg-desktop-portal.service -b -n 80 --no-pager
```

Inspect `XDG_CURRENT_DESKTOP`, backend selection, session state and PipeWire. Working file selection with failed screen sharing calls for screencast-specific diagnosis. Different interfaces can use different backends; do not blindly remove all others. [Hyprland portal](https://wiki.hypr.land/Hypr-Ecosystem/xdg-desktop-portal-hyprland/)

## Input and audio

Test native Wayland, XWayland, GTK and Qt applications separately. A running Fcitx5 process is only the first condition; application integration and the current input group also matter. See [Neovim input](../nvim/06-remote-input.md).

```bash
wpctl status
wpctl get-volume @DEFAULT_AUDIO_SINK@
```

Confirm default devices and actual playback streams before debugging shell controls. Changing the default output and moving an existing stream are distinct operations; applications may retain their route.

## Choose a narrow recovery action

| Symptom | Verify first | Recovery scope |
| --- | --- | --- |
| Shell disappears but windows work | QML and shell service logs | Repair/restart the shell |
| Binding cannot launch program | Executable path and environment | Correct the command or service environment |
| Shell survives logout | Target membership and processes | Fix stop propagation |
| Screen sharing is blank | Portal, PipeWire, session | Repair relevant backend/connection |
| Only some themes update | Template output and reload | Repair that application's pipeline |

Repeat the original trigger after recovery and test logout/login. A runtime repair does not prove the next startup sequence is correct.
