Hiya,

I've installed GhostBSD because TrueOS and Trident abandoned me. I really like Lumina WM. I've poked around and can't find out how to enable it as my default WM. Normally /etc/X11/xorg.conf or perhaps /usr/local/etc/X11/xorg.conf would do the trick, but not in this instance.

Any advice is appreciated.

You probably want to enable PCDM instead of LightDM, but you should be able to select Lumina in LightDM if not do this.
