Shutting down the laptop display

Sometimes you have to run a lot of stuff in some terminals which take a long time to compute (think of a recompile of your linux kernel or something like that). For linux users there is a simple command to shut down the display and let the system fully run meanwhile. Just type

xset dpms force off

to shut down the display in a terminal and move the cursor or hit some key on your keyboard to re-enable the output again.
