Re: VNC viewing or RPi prompt from Windows

Is VNC only for desktop sessions? Yes Normally yes, VNC servers on Linux typically rely on the X window system to provide remote access to a desktop session. However, the RealVNC Server on the Pi has a special mode which allows access to the system at the console, without X running. It also allows ...

Re: Resetting VNC Password

It sounds like you are trying to reset the password on the server? I'm assuming you're using the RealVNC service mode server here, which is what is enabled from raspi-config. By default the VNC Server will use the credentials of the users on the system, (i.e. pi/raspberry by default), and it will al...

Re: VNC Viewer on Raspberry?

The package for the RealVNC viewer is called realvnc-vnc-viewer.

You should be able to find it in add/remove software, or from the command line do "sudo apt install realvnc-vnc-viewer".

Re: Autostart an Application in TightVNCServer only works when RealVNC is installed

The RealVNC server package (realvnc-vnc-server) and the tightvncserver package conflict, meaning they cannot be installed at the same time. So installing one will result in the other being uninstalled.

Both of these packages provide the "vncserver" command, which starts a new virtual desktop.

Is your Pi set to boot to desktop? This is normally required for VNC to work, although you can get around this by enabling experimental direct capture mode, see here for how to do this from the command line: https://support.realvnc.com/knowledgebase/article/view/541/0/how-do-i-enable-the-experimenta...

Any clues or has RealVNC removed the ability to have multiple server sessions from RealVNC Server rel 6.2.1 ?
We've certainly not done that!
It should work, but as @klricks said, it's not a good idea to run vncserver via sudo. What happens if you run it as a regular user?
