I've been using tigervnc for a long time now (years), and I have never had this problem. When the KDE base was upgraded from 20.04 to 22.04 on KDE Neon, suddenly, this started. I have spent numerous hours googling this, trying various strategies, revisiting all the documentation I could find on the subject and otherwise trying to get assistance. Whatever changed, it does not appear to be documented... but I'm hoping that someone else out there with an intimate knowledge of KDE, X, VNC and Ubuntu can give me a hand here...
To keep this brief, I have stripped vnc down to the bare minimum, just for testing purposes. (I'll get fancier when I know it works!). First, I like to use tigervnc the old fashioned way: start up a server on the command line, and connect via a client on the command line. I'm not really interested in running it through systemd. Again, to keep things as simple as possible, I'm doing all my testing (client and server) on the same system. Here we go...
(which has been working for me for the past 4 years or so)
In a terminal, as my user, I execute:
I'm given the following output:
when I look at /home/me/.vnc/it-me-lin2:5901.log
This is vexing, because the display is actually accessible, and I've tried exporting when launching the server, in the xstartup script, and everywhere I can think of.
The interesting thing here is that if I issue:
It will launch. THEN I can issue dbus-launch /usr/bin/startplasma-x11 & inside the xterm it spawns, and Plasma launches...
so I'm thinking that this is somehow a SDDM or a Plasma issue of some sort. I have tried setting my xwrapper to 'Anybody', but that didn't help either. I'm not sure where to go with this. I appreciate any help.

There is something magical about taking the time to post...
I figured this one out on my own, minutes afterward. It is funny how I can spend a week of bashing my head into walls, and it isn't until I post that the answer comes to me. I tried to delete this thread... but the forum does not seem to allow me to do it, so I apologize if this seems inane.
