Oh, that's kind of sneaky:

I think the FreeDesktop folks are using a different filesystem layout,
and it does not include config files in /etc. I think the location is
XDG_CONFIG_HOME and XDG_CONFIG_DIRS, if I am reading [1] correctly. I
think XDG_CONFIG_HOME is similar to GNU's standard directory
sysconfdir.[2] (sysconfdir would typically be /etc.)

But my XDG_CONFIG_HOME is empty:

    $ echo $XDG_CONFIG_HOME
    $

And:

    $ echo $XDG_CONFIG_DIRS
    /home/jwalton/.config/kdedefaults:/etc/xdg/xdg-plasma:/etc/xdg

Maybe the TigerVNC Release Notes say something about it.
