If there's a recipe for installation, I want it.
I have a fresh install of 24.04, and I've installed
tigervncserver_1.16.80-1ubuntu1_amd64.deb (nightly, though I've also tried 1.15.90 beta)
I've run vncpasswd to create ~/.vnc/passwd
When I run:
------------------------------------------------------------
asavage@joni-31:~$ w0vncserver -rfbauth ~/.vnc/passwd -localhost=no -Log *:stderr:100
Sun Jan 11 19:23:28 2026
main: Listening for VNC connections on all interface(s), port 5900

VNCServerST: Creating single-threaded server asavage@joni-31
------------------------------------------------------------
But when I attempt to connect (via either tigervncviewer or Remmina), the viewer(s) complain that (for tigervncviewer), "The connection was dropped by the server before the session could be established", and stderr shows (prior to entering the password in the viewer):

The underlined output is not present when using Remmina as a client.
These files are un-modified from installation, and contain only comments:
/etc/tigervnc/vncserver-config-defaults ...
/etc/tigervnc/vncserver-config-mandatory
/etc/tigervnc/vncserver-config-mandatory
My understanding is that only the commandline options should be in force.
What are suggested troubleshooting steps for this situation?

Do you have a graphical session running for the user, or are you
starting w0vncserver via ssh? You need to have a graphical session
running for the user for w0vncserver to work.
To see what is going on on the dbus side, you can run 'dbus-monitor' to
see if see any clues.
FWIW, I just tested the nightly build on Ubuntu 24.04 with GNOME and
could not reproduce this issue.

Yes, the host has an active graphical session when I start
w0vncserver on the host via ssh, and when I attempt to connect to it
with the viewers.

I do know know what I'm seeing:

FWIW, I just tested the nightly build on Ubuntu 24.04 with GNOME and could not reproduce this issue.
That's encouraging. I'm going on the assumption that I've
incorrectly installed or configured, as there are too many
conflicting or out-of-date 'guides' for the installation of
tigervnc, and none for use of w0vncserver.
I've been using tigervnc server on an Ubuntu 20.04 system for five years (not Wayland, of course).

Just to note. Know that with Fedora if desktop is running wayland
you can not run a vnc session for same user. So, I use xvfc sessions,
since don't actually like wayland. Think same if you use the new
gnome dm, but classic did work I believe.
