We are working on the best way forward to deal with the requirements by some hardware for proprietary drivers. WiFi is a typical blocker, and graphics drivers can often break Kiosk Mode.
Please use this thread to list the exact packages (as best as you can detail) that you need and the hardware that you are using it with to build a DIY server.
Welcome!
Please read the original post - the idea here is to get exact packages required. “Just WiFi” is not a package.
We are discussing how best to implement this, but we want to provide the option for non-free drivers if users want them. We cannot provide those if we do not know what they are and we are currently only considering a couple well-known packages (TBA).
