I had installed Ubuntu 16.04 LTS.

Then I installed the following package:


At the log-in screen I have the options Ubuntu, Xfce session or Xubuntu session.

Please tell me which operating system is running (Ubuntu or Xubuntu) if I select Xfce session.

    It will be Ubuntu with xubuntu-desktop. ;-) – Pilot6 Jun 15 at 14:43

As you probably know, Ubuntu (as most Linux distributions) are made up out of many packages. When you install a distribution, not every package available is installed, but a certain selection of packages.

The different "flavours" of Ubuntu (Xubuntu, Kubuntu, Lubuntu and others) basically differ in what that initial selection of packages contains. Ubuntu by default installs for example the Gnome Shell desktop environment, Kubuntu installs the KDE desktop environment and so forth.

But once you've installed the distribution, you can basically "mix and match" like you did when you installed the xubuntu-desktop package. Now, your system offers you multiple desktop environments or window managers to choose from when you log in.

As for what your system technically is, it's an Ubuntu system with some additional packages installed that would by default be installed on a Xubuntu system. What exactly to call that is in the eyes of the beholder ;)

  • As I could also select "Xubuntu session" at the log-in screen, do I now have installed Xubuntu, too? – user773232 Jun 15 at 15:06
  • @user773232 Xubuntu and Ubuntu are the same OS, but with different packages. – Ray Wu Jun 15 at 15:14
  • I try to make it more clear: If I would like to post a question on askubuntu.com in future regarding my system, do I post that I have a question on Ubuntu or Xubuntu? Maybe that is important for getting a precise answer! – user773232 Jun 15 at 15:24
  • Would mention that you are using Ubuntu version, plus with desktop. Some cases it won't matter, unless problem with desktop. Would be careful with mixing too much, some desktops don't play nice together. – crip659 Jun 15 at 15:29
  • The only reason why I installed Xfce (xubuntu-desktop) was that I have noticed that my RAM (memory) is getting too little for the default Ubuntu software and I have read that Xfce needs fewer ressources! – user773232 Jun 15 at 15:38
