blank screen appears when using remmina via vnc protocol - vnc

I have installed tightvncserver on a remote server and can run it. I use Remmina to access the server via vnc protocol and it works, my only problem is the desktop does not show. The screen that shows up is just blank
Please reference the picture. Don't mind the background just the window shown.I have no idea why its showing like this

Ubuntu 20.04 x11vnc blank (not black) screen after session login

I have a remote headless server without a monitor attached with SSH access.
From what I found out the hard way, the default install does not support VNC (using vino) without a monitor attached.
Tried several things to get this working this without success.
I followed this guide on setting up x11vnc and lightdm: https://www.crazy-logic.co.uk/projects/computing/how-to-install-x11vnc-vnc-server-as-a-service-on-ubuntu-20-04-for-remote-access-or-screen-sharing
I then also tried to install xubuntu-desktop, which did not help.
The issue is:
VNC asks for password and connects. All good.
I see the session login window (with the panel at the top), everything looks ok. All good.
screenshot1
After login I only see a blank screen. Nothing responds. Right click on the desktop does not open a context menu. Not good.
screenshot2
Expected would be to see the desktop, panels, menus...etc.
How would one solve this? And what exactly is happening here. The session logs show everything is ok, no errors. But the computer is unresponsive on VNC, only the background is visible.
Note: I do not have physical access to this server. A solution via SSH would be best.

Running a GUI app on linux, without showing the gui?

I'm working with an api that requires an app to be started, the app runs a GUI on linux.
I need to punsh in some login information and then hide the app.
Is there a way I can go to the machine start the GUI and then hide it, log out, and have other users log in with out having the GUI shown, but still having the app running?
You can take a look at Xvfb http://en.wikipedia.org/wiki/Xvfb
it's a framebuffer version of X.
It will launch an X11 server without displaying it (useful with selenium for example)
Xdotool can send input to anyb xwindow, including xvfb

VNC on CentOS 5.5 + Gnome

I have successfully started a vncserver and can connect to it through the browser via 111.111.111.111:5081.
It looks like it's working because I do see the Gnome cursor (X).
However, apart from the cursor I just have a black screen. No taskbar or anything. Right click provides nothing either.
Does anyone have any idea what I need to do to get the full desktop ? I have created a new user and wondered if there is any settings that need changing.
Thanks in advance,
Alex
Your VNC server is running, but there is nothing running in it. No window manager, no desktop environment (GNOME), nothing. The cursor you are seeing is a Xserver cursor, not a GNOME cursor.
That probably means you ran the VNC server directly without using some of the friendly wrapper scripts such as vncserver. For example, if you have tightvnc installed and you run Xtightvnc directly, that's what you'll get.
For example, I usually start a VNC session (or port 5901) like this:
vncserver -geometry 1024x768 :1
Alternately, you can use x11vnc to serve your existing X desktop (instead of starting a new one in the background).
