@muslihuddin , you can delay other agent startups using the “X-GNOME-Autostart-Delay” parameter under ~/.config/autostart/

You can add a delay by opening ~/.config/autostart and edit the related files. You should add the following commands:

X-GNOME-Autostart-enabled=true
X-GNOME-Autostart-Delay=100
