Ubuntu's Qt application starts automatically at boot

Create an auto.desktop startup configuration file on the desktop (or other directories)

sudo gedit auto.desktop

Below is the text content

[Desktop Entry]
Version=1.0
Name=auto.desktop
Exec=/home/li/test/build-HelloWorld-Desktop_Qt_6_5_0_GCC_64bit-Release/HelloWorld
Icon=/home/li/Desktop/auto.png
StartupNotify=false
NoDisplay=true
Type=Application
Categories=System;Utility;Archiving;
Name[zh_CN]=auto.desktop

Give permission to the file

sudo chmod 777 auto.desktop

Copy to the /etc/xdg/autostart directory

sudo cp auto.desktop /etc/xdg/autostart

restart the system

sudo reboot

To cancel autostart, remove the corresponding files in the /etc/xdg/autostart/ directory

sudo rm -rf auto.desktop

Note: If you are not running a QT graphical interface but a terminal service, you need to use the gnome-terminal command
