How to run a script when fully booted?

  • 772

I want to do something where I animate my desktop background when the computer boots up. However, I can't seem to find a way to make it run ONLY when I can see it running. When I put the script in init.d, it seems to work, but it runs before I can see the desktop background. Can I make it only run when the computer has fully booted up, or when the user logs in?

(I am using Ubuntu 20.04 LTS)

boot init.d

  1. I ran into this same problem when trying to get a login sound played in XFCE. What I did was create a user service (called xfce4-login-sound.service) and placed the file in $HOME/.config/systemd/user:

    [Unit]
Description=XFCE4 login sound (with delay)

[Service]
ExecStartPre=/bin/sleep 3   # <--- this is the key, adjust delay as needed
Type=oneshot
ExecStart=/usr/bin/canberra-gtk-play -i desktop-login

[Install]
WantedBy=default.target

    Afterwards, I enabled the service:

    systemctl enable --now --user xfce4-login-sound.service
