Ubuntu Server Disable screen blanking

This is so simple however I always seem to forget how to do it.

I have an Ubuntu server and often want to run htop over a few days while testing something. The problem is though that the screen keeps going blank. This is fine but then I quickly want to see what the current performance is at a glance while walking past. I don't want to have to press a key to get the screen live again.

As root run the following

setterm -powersave off -blank 0

Here are a few more interesting things you can do with setterm.
