 Most commonly used lightweight desktop environments include LXDE and Xfce; they both use GTK+, which is the same underlying toolkit GNOME uses.The MATE desktop environment, a fork of GNOME 2, is comparable to Xfce in its use of RAM and processor cycles, but is often considered more as an alternative to other lightweight desktop environments.For a while, GNOME and KDE enjoyed the status of the most popular Linux desktop environments; later, other desktop environments grew in popularity.
