cRio going blank after some time idle

Solved!
Go to solution

Our project is almost ready to deployment (Thank you so much everyone here who's helped in all the errors). The last issue is that the screen is going idle after some time. How to stop it?

Hi parker,

 

which cRIO do you use? Most of them don't have a screen…

How does a "screen go idle"?

Best regards,

cRio 9039

 

Screen is connected to the Minidisplay port

 

Two issues actually

1) After some time of no activity, screen switches off

2) Display is max 1024X768. I used xRandr function to make it 1440x900 but I can't make it permanent nor save some script to change the size, unless I have to do it via Labview?

Hi parker,

 

1. Generate "activity" at regular intervals to avoid screen switching off…

2. I haven't worked with Linux on the cRIOs until now, but I guess usual batch files are allowed on cRIO as well… (Can't you use SysExec when you start your cRIO RTEXE?)

Best regards,
GerdW

Fixed the batch file, but how do I generate activity? My VI is supposedly working continuously to display output, but I'm assuming I have to do something else as well?

Hi parker,

 

in my experience you need to simulate mouse movement or key press events to fake user input.

I guess you will find tools for Linux helping you with this problem…

I would imagine there is a setting somewhere in the Linux configuration for setting the display timeout.  Finding that would be a better solution.
