I simply installed:
sudo apt install ubuntu-desktop-minimal -y
sudo apt install xrdp -y
systemctl status xrdp
and was able to connect with Remote Desktop from Windows as root user:
but it worked terribly slow.
And I was unable to login with a regular user:
LXQT worked a bit better:
sudo apt install lxqt -y
sudo apt install xrdp -y
systemctl status xrdp
Resized my VPS to 8GB RAM:
And it still worked slow:
df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 795M 1.2M 794M 1% /run
/dev/sda 24G 6.8G 17G 29% /

But VNC server worked fast enough:
vncserver -geometry 1920x1200
vncserver -geometry 1400x850
