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.
