After some time the monitor goes to standby mode. I want to wake up the monitor by a shell script. I already can wake up the monitor itself by
xset -display "$DISPLAY" dpms force on. But I only see a black screen with the mouse pointer. And as side effect it does not go to sleep after another couple of minutes.
What I want is to wake the monitor and Ubuntu like when I move the mouse or press any key but without really doing this! So xdotool is not a solution. I see whats going on on the screen and after some minutes it goes to sleep again.
How to get this done?
