[ubuntu_mate] VNC options for Ubuntu MATE 20.04?

I have been using various flavors of VNC for many years on and between various Linux distros/versions and even Windoze. Recently I installed Ubuntu Mate 20.04 on a couple of machines. On Ubuntu Mate 18.08 and CentOS 7 I am currently using Tigervnc with excellent results. On 20.04… no go. Some excellent instructions on TecMint show me what appears to be the root cause of my issues


[email protected]:~$ sudo apt install tigervnc-standalone-server tigervnc-common tigervnc-xorg-extension tigervnc-viewer

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 tigervnc-xorg-extension : Depends: xserver-xorg-core (>= 2:1.7.7)
E: Unable to correct problems, you have held broken packages.

The version of xserver-xorg-core which is available in the repos would remove the Mate desktop if I tried to install it 😡 If I install tigervnc-standalone-server without the extension package the server will run but I am unable to start a desktop to which I can connect.

I have installed and run x11vnc. However, the numeric keyboard does not work/

I have installed and run vnc4server. It works reasonably well except that I cannot connect over vnc if I have the console on the machine logged in or I connect via vnc I cannot logon to the console. I have read that this is a known limitation.

Tigervnc is my preferred option. Does anyone have any ideas how to work around the issues I described above?
