I tried installing tightvnc server using https://serverspace.io/support/help/install-tightvnc-server-on-ubuntu-20-04/
The log file says there is an active X-server already running so the xfce4 does not start (I think).
This also causes tightvnc to use port 5902.
Connecting vnc viewer to 5902 gives me a grey screen. I guess because no xfce.
The runing xserver On 5901 is listed as gnome-shell.
Connecting vnc viewer to 5901 gets connection refused by host.
I think I saw somewhere that the ubuntu desktop uses gnome-shell but don't know.
Can I disable the gnome-shell thing? I don't know where is gets started.
If it's required how to change startup configuration to coexist?
