In my previous article I’ve tried to investigate the RAM memory requirements for running some of the most common light window managers and desktop environments available in the Linux world. Prompted by a number of readers, I’ve decided to include also the big, well-known memory hogs that grab most of the Linux market, i.e. KDE, Unity and Gnome 3.
I am using the same setup, based on virtenv. It includes its own xserver (Xephyr) and a virtualization container (LXC). The computer is an older 64-bit machine, running Ubuntu 12.04 with LXDE as desktop environment.
