init.dスクリプトを手動で呼び出すとうまくいきますが、起動時には機能しないのはなぜですか？

私の目標

起動時に引数を使用してx.fluxを実行する

私の試み

init.dスクリプト。手動で呼び出し可能

sudo /etc/init.d/xflux start
[ ok ] Starting xflux (via systemctl): xflux.service.

私の質問

"x.flux"プログラムが起動した後、正しく実行されません。つまり、画面が期待どおり赤に変わりません。 CLIから起動した後、同じパラメータを使用して手動で呼び出すと、期待どおりに機能します。

ログと仮定

私は受け取った

sudo service xflux status
● xflux.service - LSB: xflux start script
   Loaded: loaded (/etc/init.d/xflux; generated; vendor preset: enabled)
   Active: inactive (dead) since [...] CEST; 18min ago
     Docs: man:systemd-sysv-generator(8)

  Process: 4065 ExecStart=/etc/init.d/xflux start (code=exited, status=0/SUCCESS)

systemd[1]: Starting LSB: xflux start script...
xflux[4065]: Couldn't open display (null)
xflux[4065]: .

xflux[4065]: --------

xflux[4065]: This will only work if you're running X on console.
systemd[1]: Started LSB: xflux start script.
systemd[1]: Stopping LSB: xflux start script...
systemd[1]: Stopped LSB: xflux start script.

だからこれはすることができます空のエラーが表示され、開けません。この問題を解決する方法しかし、これが実際に問題であれば、どのように解決するのかわかりません。
