Install them, i.e. `sudo dnf install mako waybar swaybg swayidle` +2. `mako` and `waybar` provide systemd units out of the box, so you can simply add them to the niri session: + + ``` + systemctl --user add-wants niri.service mako.service + systemctl --user add-wants niri.service waybar.service + ``` + + This will create links in `~/.config/systemd/user/niri.service.wants/`, a special systemd folder for services that need to start together with `niri.service`. + +3. `swaybg` does not provide a systemd unit, since you need to pass the background image as a command-line argument. + So we will make our own. + Create `~/.config/systemd/user/swaybg.service` with the following contents: + + ```systemd + [Unit] + PartOf=graphical-session.target + After=graphical-session.target + Requisite=graphical-session.target + + [Service] + ExecStart=/usr/bin/swaybg -m fill -i "%h/Pictures/LakeSide.png" + Restart=on-failure + ``` + + Replace the image path with the one you want. + `%h` is expanded to your home directory. + + After editing `swaybg.service`, run `systemctl --user daemon-reload` so systemd picks up the changes in the file. + + Now, add it to the niri session: + + ``` + systemctl --user add-wants niri.service swaybg.service + ``` + +4. `swayidle` similarly does not provide a service, so we will also make our own. + Create `~/.config/systemd/user/swayidle.service` with the following contents: + + ```systemd + [Unit] + PartOf=graphical-session.target + After=graphical-session.target + Requisite=graphical-session.target + + [Service] + ExecStart=/usr/bin/swayidle -w timeout 601 'niri msg action power-off-monitors' timeout 600 'swaylock -f' before-sleep 'swaylock -f' + Restart=on-failure + ``` + + Then, run `systemctl --user daemon-reload` and add it to the niri session: + + ``` + systemctl --user add-wants niri.service swayidle.service + ``` + +That's it! +Now these three utilities will be started together with the niri session and stopped when it exits. +You can also restart them with a command like `systemctl --user restart waybar.service`, for example after editing their config files. + +To remove a service from niri startup, remove its symbolic link from `~/.config/systemd/user/niri.service.wants/`. +Then, run `systemctl --user daemon-reload`. + +### Running Programs Across Logout + +When running niri as a session, exiting it (logging out) will kill all programs that you've started within. However, sometimes you want a program, like `tmux`, `dtach` or similar, to persist in this case. To do this, run it in a transient systemd scope: + +``` +systemd-run --user --scope tmux new-session +``` -- cgit
