Major Updates

Xubuntu Community Wallpaper Contest

Xubuntu hosted a community wallpaper contest from February 28 through March 13, 2020. 6 winners were selected from a total 237 submissions. The selection was based on a team vote. Thank you to everyone for your submissions!

Greybird Dark Theme

Xubuntu 20.04 ships with a brand new optional theme, Greybird-dark. To switch from the default Greybird to Greybird-dark, open your Settings Manager and:

  • Click “Appearance”. Select “Greybird-dark”.
  • Click “All Settings”.
  • Click “Window Manager”. Select “Greybird-dark”.

Greybird-dark makes your entire desktop darker while still maintaining a usable contrast.

Desktop Integration

gedit installed as a Debian package, Snap, and Flatpak


Our desktop themes Greybird, Greybird-dark, and elementary-xfce are now included in the gtk-common-themes snap. When using any of these themes, you can expect snap packages to fit in perfectly with the rest of your desktop. Snaps work out of the box on Xubuntu, and can be installed with the included GNOME Software.


Greybird and Greybird-dark are available to install on Flathub! If you use Flatpaks on your system, you can install our themes and enjoy a consistent desktop experience with the following commands.

flatpak install org.gtk.Gtk3theme.Greybird
flatpak install org.gtk.Gtk3theme.Greybird-dark


Python 2

With Python 2 now officially End of Life as of January 1, 2020, Ubuntu and its various flavors are no longer shipping Python 2. Xubuntu includes only Python 3.8 as of 20.04.

Apt Offline

apt-offline is no longer included in Xubuntu 20.04. Until February, it depended on Python 2 and was thus removed from the Xubuntu and Ubuntu Studio seeds.

Pidgin Libnotify Plugin

pidgin-libnotify is no longer included in the Ubuntu repositories and has thus been removed from Xubuntu.
