Make Shit Just Work on a GNU/Linux computer running as a media box for a TV.

Tested on Linux Mint (based on Ubuntu, based on Debian). Should work elsewhere, send me patches if not.

• Disable computer auto-suspend and TV auto-off, when audio (incl. video) is playing.
• Switch on TV and make it source the computer, when the latter wakes from suspend.

Due to limitations of both common computers and TVs, you will very likely need the following:

• To enable your computer to speak HDMI-CEC:
  • Special DP-to-HDMI adapter, e.g. P/N 2JA63AA from HP.
  • See cec-autostart for details and alternatives.
• To enable your computer to switch your TV on via IR Remote Control, if/when its HDMI-CEC and Wake-on-LAN are both off:
  • USB-to-GPIO breakout board with bitbang mode, e.g. Adafruit FT232H.
  • IR transmitter and receiver GPIO modules, commonly available.
  • DuPont/jump wires and a USB-C cable to hook these up to the computer.
  • See config/vars.example for details and alternatives.

Make sure both HDMI-CEC and Wake-on-LAN are enabled on your TV, if possible.
