Greetings to all Ubuntu enthusiasts.

I am looking for an Ubuntu solution for my problem. I want to load Ubuntu without GPU on mobile phones. When installing Ubuntu on a mobile phone, I want to enter the Wi-Fi name, Wi-Fi password and command to download a program that will start itself every time it starts. I would not mind connecting the program directly to the Rom, including its configuration, so that when the mobile phone is turned on, the application can start without problems. I don't need remote access to Ubuntu or the program. I have monitoring that tells me if the program is running. I want to run two programs simultaneously in Ubuntu without a graphical environment. one using the CPU and one using the GPU. Can I find a solution to my problem somewhere?
