Minimal Ubuntu with FluxboxUbuntu is going to use Unity instead of Gnome 3 as default window manager. For me both needs getting used to. So I've been looking for alternative desktop environments and window managers.
Ultimately I decided to use a minimal Ubuntu installation with Fluxbox as window manager. As Fluxbox is very fast and only needed packages are installed the whole System feels quick.
And this how it looks like:
If you are bored of Unitiy and Gnome, too. Install minimal Ubuntu and following packages
sudo apt-get install xorg fluxbox slim xfe chromium-browser
and you are done!
