如何在不安装不同桌面的情况下最终在 18.04 上启动 VNC 服务器？

Question

I moved one of my desktop to Ubuntu to try it. In Centos 7, all I need to do to launch a VNC server and see my desktop remotely is: yum install tigervnc-server xorg-x11-fonts-Type1 and vncserver. And I can see correctly my desktop as if I was in front of the monitor. No need to modify any xstartup file or anything!

The question comes back again and again without acceptable answer then I have few more:

1. Why nobody could do it in Ubuntu yet?
   • If Unity or for whatever reason it isn't possible, let me know.

2. Why 99% of the tutorials required us to install xfce?!

   • I don't want to install anything else Finally, for an ultimate time:

3. Is there a proper way to install a VNC server without modifying xstartup, and without installing a tier desktop?

I don't expect a simple answer here, if you provide a xstartup file, I'd like to get all the explanations. No need to get the same what I can read in the hundreds duplicated blogs.

Answer 1

Controlling current desktop currently is a standard feature of Ubuntu
It is called 'desktop sharing'.
VNC server is installed by the vino package and his setup available in the gnome-control-center sharing

See Cannot turn on sharing on ubuntu 18.04

sudo apt install vino
gnome-control-center sharing &
