A bit of a boring reply but I think AIs have already solved this. AIs might not be able to handle lack of documentation but I think they solve the "How to read this manual" part. Anecdote: I've spent about 20 minutes trying to figure out how can I turn off a monitor with xrandr but still keep it's desktop contents in the same place and struggled to find anything useful, every single search result was about turning off the monitor conveniently missing the important part about keeping the contents there (I realize this is in part a DE/WM issue as well, I'm simplifying for the sake of this message). In any case, I've asked chatgpt and immediately suggesting setting brightness to 0 or using Xvfb to create a virtual buffer both solutions being satisfactory for what I needed.
