>OT - I just stripped off all the bloat from my two ubuntu computers - gnome, unity, kde, xfce. Only gtk and some very basic gnome libraries remain, with software like libreoffice, evince, inkscape, gimp, and of course latex/emacs/compilers etc remain. I'm using the i3 window manager. It feels so much faster and I'm so much happier.
Why install Ubuntu in the first place? Allow me to recommend Debian and Gentoo.
