I can't give you all details to complete your task, but I have a distribution which at boot start a browser which connects itself to a specific URL that to a specific IP address.
Essentially you need the following steps:
Script to start the browser (in kiosk mode)
You have to create the bash script start-browser.sh and save in in the folder Save it in the home folder /home/username`. I suppose you are using Firefox as browser, so the content of the script at least the followed command:
/usr/bin/firefox --kiosk <URL> &
In the previous script is present only a command where:
- you have to set the
<URL>
- Firefox is started with the option
--kiosk but this option can be removed if it isn't necessary; this option restricts the access to the other applications present in the distribution
Remember to set executable the script by:
sudo chmod +x /home/username/start-browser.sh
Start the script by Autostart
To start the script at boot I suggest you to add the script to the Autostart of the Desktop Manager by the menu Preferences. In this moment I don't have a Ubuntu distribution installed but only a lubuntu distribution. In lubuntu 22.04 to add start-browser.sh to the Autostart you have to select, by the Start button the menu:
Preference->LXQT Settings->Session Settings->Autostart
In this moment is not easy for me add useful screenshot to reach this menu and show how to add the script for Autostart.
I think with the previous two steps at boot, the Ubuntu distribution start Firefox at full screen and in kiosk mode.
