I'm currently working on a RPi 3B+ with RaspberryOS (NOT the lite version), programming a Python GUI for a life-size game. I'm trying to change how the OS behaves. I do not have experience doing that.
My GUI works but it needs to stay in focus and that's where I have problems.
Players will have to plug in a USB key to the RPi. For now, when they do, a "new media plugged-in" popup comes up. That's a problem for what I'm doing.
So : How to turn off pop-ups and notifications ? (The USB key still needs to be detected)
Alternatively : Is booting in console mode and starting my gui in a single X window a better way to avoid the problem ? (that seems very complicated for my skillset, but maybe that's the correct path ?)
Edit : Found it ! Thanks for pointing out that this feature is part of the file manager, it can actually be disabled in the options of the file manager, I was simply looking in the wrong place with the OS.
