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 mark@facebook.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
