System: laptop with HDD(no money for ssd) and power issues + old non-smart TV + router under TV OS: Fedora server

Idea: Since the old laptop is close enough to the router for Ethernet, I’m using it as a home server. Then I had the idea to also use it as a smart TV like device since it’s right under the TV. I figured an HDD wouldn’t be a huge issue for streaming from jellyfin or the internet.

Server side stuff I’ve found lots of great information on but I’m struggling with the roku-like/smart TV setup:

• how do I disable the laptops display on boot?
• using waydroid + cage to run full screen android application when tv is connected?
• can the TV remote be mapped to Linux inputs?
