In an existing Wayland or X11 session, You can also specify a startup program using the `-s` option. The argument to this option will be run at startup as a shell command (using `sh -c`) and can serve a similar function to `.xinitrc`: starting a service manager or other startup applications. Unlike `.xinitrc`, the display server will not shut down when this process terminates. Instead, as dwl is shutting down, it will send this process a SIGTERM and wait for it to terminate (if it hasn't already). This makes it ideal not only for initialization but also for execing into a user-level service manager like s6 or `systemd --user`. -More/less verbose output can be requested with flags as well: - -* `-q`: quiet (log level WLR_SILENT) -* `-v`: verbose (log level WLR_INFO) -* `-d`: debug (log level WLR_DEBUG) - Note: Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a session manager such as `elogind` or `systemd-logind`.
