Issue Details

When deploying a VI to a Real-Time (RT) target, my text doesn't display the font size on the Real-Time device the same way as it does on my development system. How can I fix the font sizes?


Fonts are not correctly installed initially on the LabVIEW RT 2016 Embedded UI. Therefore, to properly install the fonts, run the following command from the shell with administrative privileges.
  1. Access the shell on your Real-Time device using an administrator account
  2. Enter the following shell command:  
    find /usr/share/fonts/X11 -type d -print0 | xargs -0 mkfontdir
After running the command, restart the target and the fonts will display properly. 

Additional Information

Reformatting the target will require you to run the command again after software is reinstalled to the target.
