I want to install a vnc-server on a Ubuntu 18.04 desktop (clean install). I've tried vino, tigervnc, tightvnc. For vino, I don't get the screensharing option in the settings. For tigervnc and tightvnc the installation proceeds, I create the configuration, but when I try to connect I get a grey screen with a cross cursor.
I've tried a VM (clean installation) with Ubuntu 19.04 desktop and vino-server, turned screen sharing on. When I tried to connect with Remmina from the host, I get a black screen, no cursor.
I'm lost here, have spent hours to get this working, thought this should be a straightforward thing to do.
How can I get screensharing via VNC to work?
SSH is running, UFW disabled.
