Following is my opinion, agree, disagree, tell me I'm full of crap, "it's all good". I'm trying to address this statement by
tgl:
"In order to create an interest around the dekstop use leaving the OS without a default DE/WM is contradictory."
Lumina: great idea, not enough manpower to get over the finish line. Adequate desktop environment if that's what you want/need.
KDE/Gnome: My opinion like all desktop environments too much, too bloated, not what I want/need.
FreeBSD and Desktops. This has been "the topic" for as long as I can remember (and we're talking about 3.x days). I have never given it much thought. Why? Any computer use is about the applications. What applications do I need, what applications do I want. Everything else is a lesser concern.
Stability of the base OS is a good thing, it's like the foundation of the house. But you can have the best foundation in the world and a house that doesn't support your needs.
FreeBSD is a stable foundation. Maybe not always the fastest, maybe not always the latest hardware support, but in general for most workloads, it fast enough and stable enough.
Applications (the house): what are you doing. Simple text editing? Vi and a console work fine for that. Digital photography/video editing? Completely different requirements. Figure out what you want (oh darktable is pretty darn good for photo editing by the way)
So now we have a foundation and a house. What colors, what flooring, what appliances? To me that is the DE/WM bits. We are into personal preference, personal opinions. I like blue wall paint (KDE) you like yellow (Gnome). Why should there be a blue default? Why should there be a yellow default? As soon as you pick one, you'll have someone that likes greens (stacking window manager) and you can't sell the house.
If you're still reading, thank you.
I don't want FreeBSD proper to have a default desktop environment or window manager. I want it to install a solid foundation that I can build upon to create the computing environment that I like, that make ME productive. That is exactly what we get from current FreeBSD.
If you want "A FreeBSD that installs a desktop environment of KDE/Gnome by default" then look for a distribution that does that.
Sorry if this got long and opinionated, but hey, it's Friday and snow's coming in.
