Man, I have an intel iGPU myself, in a little Dell optiplex 7090 and it was a breeze on my Debian sever. Installed through apt and it’s running as a systemd service. No issues so far. Only one issue I had was when I played a 70GB 4k HDR movie that’s loaded with audio and subs and picture enhancements on my OLED TV. The server’s little fan was screaming and the movie kept pausing every 20 seconds. Other than that I have a ton of other movies and shows and I have no issues.
