Issue Details

My cRIO detects my monitor plugged using Mini DisplayPort when the monitor is already on. However, unplugging and replugging the cable causes the display to not turn back on again. Is this by design? Is there some kind of way to re-enable the display?


  • Use the "System Exec. vi" in a loop on your RealTime target and enter in the command line "xrandr --auto --display :0". If you set the timing of the loop to 2000ms, every 2 seconds the RealTime target will generate an event to turn on the screen, if the screen is in standby or power safe mode.
