I currently have xubuntu installed on my netbook, and I'm considering converting it to the standard vanilla Ubuntu. Is this possible? If so, how do I start?
You'll simply need to install the
ubuntu-desktop meta-package. This installs all the nessisary packages for a "Vanilla" Ubuntu Desktop.
sudo apt-get install ubuntu-desktop Once this has been completed you can restart your computer. At the login screen you can switch from XFCE to Ubuntu Desktop under the Session dropdown. Doing so will load the Gnome desktop.
If you're satisfied with Ubuntu Desktop and wish to remove xubuntu you can always remove the meta package
xubuntu-desktop which will remove the meta-package. If you wish to remove all the packages from the xubuntu-desktop meta package you'll have to remove those by hand. An updated list of all the packages by distrobution is available simply copy the line for your version of Ubuntu
You can simply install all standart ubuntu package with
sudo apt install ubuntu-desktop
Then when you feel good with your new environement
sudo apt purge xubuntu-desktop sudo apt autoremove
And don't forget to reconfigure GDM3 login
sudo dpkg-reconfigure gdm3
Also you may want to change Ubuntu loading screen. It is realy easy, check this answer.

Since xubuntu-destkop is a metapackage removing it will not remove the other underlying packages. The link above tells you which ones you need
