How I start a editor "mousepad" in Linux Real-Time OS for LabVIEW in a new windows

[The_NewOne]

Hello

I used a cDAQ-9132 chassis with Linux Real-Time OS and I just want to start a editor "mousepad" in a new window from LabView 2017. But I get an error meassage.

I used System Exec.vi and give as comment "mousepad /media/sdc/text.txt" but the file don't open in editor. When I used the same comment in terminal on the device the editor is opening.

How to start an aplication from LabView in Linux? Where is the mistake?

Thank you

Someone with more experience than me can probably help more.  But my first thought is, is this a user issue?  Like the LabVIEW program running under the account LVUser and the desktop environment running under Admin.  The error of "cannot open display" makes me think that bash doesn't even know there is a shell running.  Is there a command in Linux to run an application as a specific user?  If so I'd try that.
