A desktop environment is a collection of software designed to give functionality and a certain look and feel to an operating system.. This article applies to operating systems which are capable of running the X Window System, mostly Unix and Unix-like operating systems such as Linux, Minix, illumos, Solaris, AIX, FreeBSD and Mac OS X.

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.
Xfce's Xfwm (since 4.2 of 2004 [citation needed] or 2005 Xfce 4.2.0 released!), Unity's Compiz (since 2005—was forked as Beryl in 2006 but the projects re-merged in 2007), and; KDE's KWin (since 4.0 of 2008). Compositing support can be added to non-compositing window managers, through the use of compositors such as compton.
Graphical elements such as buttons, menus, icons, etc. are all realized using windows. A window can only be created as a subwindow of a parent window. This causes the windows to be arranged hierarchically in a tree. The X server automatically creates the root of the tree, called the root window. The top-level windows are exactly the direct ...
In the extreme case - user can use a computer without a GUI and even browse the internet in a terminal, without images, in Lynx, on a weak computer. A light-weight Linux distribution is a Linux distribution that uses lower memory and processor-speed requirements than a more "feature-rich" Linux distribution.
LXDE (abbreviation for Lightweight X11 Desktop Environment) is a free desktop environment with comparatively low resource requirements. This makes it especially suitable for use on older or resource-constrained personal computers [ 2 ] such as netbooks or system on a chip computers.
Besides the Linux distributions designed for general-purpose use on desktops and servers, distributions may be specialized for different purposes including computer architecture support, embedded systems, stability, security, localization to a specific region or language, targeting of specific user groups, support for real-time applications, or commitment to a given desktop environment.
