Raspi fullscreen

[carmarsi]

My raspberry execute a program at startup which is in fullscreen. I added a code line to stop the execution with a specific key, but the keyboard doesn't respond and I don't know how to stop it or how to reboot without executing it. The GPIO ports are working well. I tried all the possible comand to stop execution on the keyboard but it doesn't do anything. I need help.

Thanks to all for helping.

There is no information there for anyone to help you out.

An unknown program isn't acting the way you want, you've added some unknown script to an undisclosed location to try to change the behavior, somehow GPIO pins are involved, and all attempts trying to stop it using the keyboard have failed.
