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 several 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.
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.
