I'm trying to configure Gnome-Desktop on Ubuntu 20.04 LTS.
I'm able to view the desktop with Real VNC Viewer, Apple VNC Screen Share and other VNC viewers, I can run my applications, the desktop manager works, copy/paste works within the server, etc.
However, the background is gray (no wallpaper), the icons are missing (e.g. clock, audio, etc.), copy/paste does not work between the client and server, right click doesn't work.
Here's what I installed:
sudo apt-get install ubuntu-gnome-desktop
sudo apt-get install tightvncserver xtightvncviewer tightvnc-java
sudo locale-gen de_DE.UTF-8
sudo apt-get install xfonts-75dpi
sudo apt-get install xfonts-100dpi
sudo apt-get install gnome-panel
sudo apt-get install metacity
sudo apt-get install light-themes
touch ~/.Xresources
vncpasswd
Here's my ~/.vnc/xstartup file:
#!/bin/sh
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
export XKL_XMODMAP_DISABLE=1
export XDG_CURRENT_DESKTOP="GNOME-Flashback:Unity"
export XDG_MENU_PREFIX="gnome-flashback-"
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-session --session=gnome-flashback-metacity --disable-acceleration-check &
gnome-panel &
gnome-settings-daemon &
metacity &
nautilus &
gnome-terminal & 1,1
Here's what my screen looks like 
There are three versions of dbus on Ubuntu 20.04 LTS:
