Screen sharing which is using VNC protocol you can easily set by using a mouse in the setting Sharing cection ... if it is hard for you I can provide the link for the article with a detailed description.

Below you can find additional links which may be useful too... )) I have met some difficult situations for beginner Ubuntu users... so there are some useful links.

#when I had problems with the virtualbox clipboard:
https://askubuntu.com/questions/533071/virtualbox-4-12-shared-clipboard-not-working-in-ubuntu14-04

sudo apt-get install virtualbox-guest-x11
sudo VBoxClient --clipboard

You don't need to install all the virtualbox-*. I installed virtualbox-guest-dkms, which depends on virtualbox-guest-utils, and it recommended I install virtualbox-guest-x11, so I did so as well. It appears that the guest additions are working, and then $ reboot.

For me, I couldn't enable screen sharing, because I was running in "Wayland" (as that was the only desktop I could use). Well, Wayland doesn't support the screen-sharing option. I fixed this issue by switching to the original XOrg "Ubuntu" desktop. In order to get that to work, however, there was a battle...

I had this problem from two new installs of 18.04. The fix that worked was running code below in a terminal and then rebooting:

sudo apt install vino

Use x0vncserver as explained in how to start a vnc server for the actual display (https://www.howtoforge.com/tutorial/how-to-start-a-vnc-server-for-the-actual-display-scraping-with-tigervnc/).

sudo apt-get install tigervnc-scraping-server
Then set a password

vncpasswd
Then start the server with

 x0vncserver -passwordfile ~/.vnc/passwd -display :0
---- end (for x0vncserver) part.

Замена логин скрина для поддержки входа через VNC (it was one of the most important parts after I've installed RDP server, it's substitution of login screen which isn't able to connect VNC to display, only to a session which isn't suitable for me, so I've used this tutorial too, and it worked.
