What Others Think

no neg from me, but it would be nice for the OP to leave a comment when posting a funny one-liner. . xset dpms force on|off is to turn on and off energy-star features xset s reset does something with the screen saver sleep 0.3 might not work in some systems that do not accept anything except whole seconds.

yeah the 0.3 secs gets rounded to 1 sec on some systems. although meant for amusement, it does show a simple way to switch the display on/off combine with a system beep (CTRL-G) for extra annoyance ;-)
