I love the command line, I use the command line A LOT - but there was this one time (in bandcamp) where I lost nearly 20GB of data by using the command line, and wouldn't have done if there was a GUI, that is why I add one now!. This one is lightweight. If the CLI fanboys want to complain to me about why I shouldn't use one, my email address is email@example.com!
Now for those commands:
sudo apt-get update && sudo apt-get upgrade sudo add-apt-repository universe sudo apt install tasksel sudo tasksel install xubuntu-core sudo service lightdm start sudo apt install xrdp sudo systemctl enable xrdp
