I’m using Ubuntu 18.04.
I usually using In text mode to display video images on the monitor.
I create a shell script.
Start to “startx” when the mouse is connected.
“startx” is stopped when the mouse is removed from USB port.
I want to video images display again on the monitor when return to text mode from the “startx”.
But, when the “startx” is stopped, the monitor says “No Input Signal” and goes completely black, and stays that way. The LED power light is amber/yellow.
Start to “startx” again, monitor is display again.
How do I disable power save mode for monitor?
