Conditional Disable Symbols in the Headless Linux Runtime Engine

[CantankerousBullMoose]

Is there a symbol for conditional disable structures that indicates whether an application is running in the headless Linux RTE as described here?  I need parts of my application to work differently when there is no GUI

If it's not listed here, then I guess not.  If you can detect what mode you're in, you can create a custom symbol and set it according to the mode.
