Ask HN: How to setup a distraction-free Linux setup for writing

There's no way around it: if there's internet available, I'll disperse. I thought about buying one of those modern typewriters (like the Freewrite), but they're expensive or impossible to find where I live.

I thought: I'm going to take my old notebook and install Linux that will only be used for writing only. What do you recommend installing for this purpose? I have intermediate knowledge of Linux, but I didn't want to spend a lot of time configuring it.
