VNC connection problem between Windows RealVNC viewer and Ubuntu 18.04 TightVNC server

  • 772

I want to establish VNC session between RealVNC Viewer in Windows 10 and TightVNC server in Ubuntu 18.04. I want to see from Windows full Ubuntu desktop. I looked at following resources: Configuring a VNC Desktop: Upgrading GUI from classic gnome desktop to newest gnome desktop How to configure VNC server to get full Gnome desktop? vnc service for ubuntu 18.04, no background and menus How to make VNC Server work with ubuntu-desktop without xfce
ubuntu 18.04 VNC Grey screen

I have used various variants of the xstartup file ~/.vnc/xstartup. However, I cannot find any configuration which is working for me. Below you can find example of the xstartup file. Ping is working and I can ssh from Windows to Ubuntu. VNC connection is also working. However, after establishing VNC session from Windows machine, I cannot see anything.I get an empty window with grey background. From Linux machine I use Remmina for connection with similar result. I want to see exactly the same desktop as if I am looking at the Ubuntu machine, but I cannot do that.

I would appreciate your help very much.

    #!/bin/sh

    export XKL_XMODMAP_DISABLE=1
    #xrdb $HOME/.Xresources
    unset SESSION_MANAGER
    unset DBUS_SESSION_BUS_ADDRESS
    #exec /etc/X11/xinit/xinitrc

    [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
    [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

  1. If you want to export your full desktop via VNC, don't use any third-party VNC servers, use "vino" which is integrated with GNOME and exports the full GNOME desktop. I have used it on 18.04 with success, now use it on 20.04. There are however some config parameters you have to set for vino-server, look at the answer here: what is the easy/minimal way to remotely connect a Ubuntu 20.04 system from another Ubuntu 20.04 system?
