Just downloaded the most recent version of Xubuntu 15.10 Beta 1 and run it on my Lenovo ThinkPad E440 laptop series. Xubuntu 15.10 is an Ubuntu spin which uses Xfce as the default desktop environment. Xfce is a simple and lightweight desktop that works on old or new computers. Xubuntu 15.10 Beta 1 is powered by Linux Kernel 4.1.0. It comes with many applications such as Firefox, LibreOffice and many more.
