Hey all,
First post here. I've done several hours of Googling and a search in these forums. Can't find anything, hopefully someone can help!
I don't think this is an issue with NoMachine itself, but I also admit I'm almost completely unfamiliar with dbus, so forgive my naiveté. There is a server config for NoMachine where you can specify the command to start a desktop environment if no existing X server is running (which I don't have any other X servers running -- I don't think... how can I doublecheck?). I do have xorg-server installed and I uninstalled lightdm and sddm, which I was playing around with earlier.
Example from the NoMachine server config (/usr/NX/etc/node.cfg):
# Specify path and name of the command to start a new virtual desktop,
# by default the X session set on the system.
#
#DefaultDesktopCommand "/usr/sbin/dbus-launch --exit-with-session startkde"
DefaultDesktopCommand "/usr/sbin/dbus-launch --exit-with-session startxfce4"
I've tried this line with and without `/usr/sbin/dbus-launch --exit-with-session`
When I try xfce4, I can connect, but I get a black screen with a dialog stating:
Unable to contact settings server
Failed to connect to socket /tmp/dbus-XXXXXXXXXX: Connection refused
When I try KDE/Plasma, I get a black screen with a dialog:
Could not sync environment to dbus.
Any help? Obviously, I'd be more than happy to provide any additional info.

I've just read the NoMachine and Xorg wikis because something stands out as missing in your post. Do you have a fake display configured for xorg, an xf86 video dummy installed, or a physical dummy plug on the server?
An X session isn't going to start without something like that, unless there's something I'm not understanding about NoMachine.
