|Desktops & Window Managers
KDE - is a powerful Open Source graphical desktop environment for Unix workstations. It combines ease of use, contemporary functionality, and outstanding graphical design with the technological superiority of the Unix operating system.
Gnome - The GNOME Project is an effort to create a complete, free and easy-to-use desktop environment for users, as well as a powerful application development framework for software developers. GNOME is part of The GNU Project, and is Free Software.
Mate Desktop Environment - For those of you who still feel GNOME 2 is the best desktop environment, but don't want stick to old distros, MATE is a fork of GNOME 2, with all the names changed to avoid clashes with GNOME 3.
XFCE - is a lightweight desktop environment for various UNIX systems. The goal is keep most system resources for the applications, and not to consume all memory and CPU usage with the desktop environment. XFce is based on GTK+.
Razor-qt - is an advanced, easy-to-use, and fast desktop environment based on Qt technologies. It has been tailored for users who value simplicity, speed, and an intuitive interface. Unlike most desktop environments, Razor-qt also works fine with weak machines.
LXDE ("Lightweight X11 Desktop Environment") - is an extremely faster, performing and energy saving desktop environment. It is maintained by an international community of developers and comes with a beautiful interface, multi-language support, standard keyboard short cuts and additional features like tabbed file browsing. LXDE uses less CPU and less RAM. It is especially designed for cloud computers with low hardware specifications like netbooks, mobile devices (e.g. MIDs) or older computers.
XPde - is a desktop environment (XPde) and a window manager (XPwm) for Linux. It tries to make easier for Windows XP users to use a Linux box.
Blackbox - is a fast, light window manager without all those annoying library dependancies.
Fluxbox - is based on the Blackbox 0.61.1 code. Fluxbox looks like blackbox and handles styles, colors, window placement and similar thing exactly like blackbox (100% theme/style compability).
Enlightenment - is a completely themeable, highly configurable Window Manager.
amiwm - is an X window manager that tries to make your display look and feel like an Amiga Workbench screen. It is fully functional and can do all the usual window manager stuff, like moving and resizing windows.
Sawfish - is an extensible window manager using a Lisp-based scripting language --all window decorations are configurable and all user-interface policy is controlled through the extension language.
IceWM - is a fast to use and simple window manager for the X11 Window System. It combines the best features of other window managers and GUIs. Themes can customize the look, user can customize the feel.
Flwm - stands for: "Fast Light Window Manager". "Flwm is my attempt to combine the best ideas I have seen in several window managers. The primary influence and code base is from wm2 by Chris Cannam."
Window Maker - is an X11 window manager originally designed to provide integration support for the GNUstep Desktop Environment. It is fast, feature rich, easy to configure, and easy to use.
Afterstep - Originally based on the look and feel of the NeXTStep interface, it has evolved into its own creature.
Ion - is a tiling tabbed window manager designed with keyboard users in mind.
FVWM - is an extremely powerful ICCCM-compliant multiple virtual desktop window manager for the X Window system. Development is active, and support is excellent.
evilwm - is a minimalist window manager. "Minimalist" here doesn't mean it's too bare to be usable - it just means it omits a lot of the stuff that make other window managers unusable.
awesome - is a highly configurable, next generation framework window manager for X. It is very fast, extensible and licensed under the GNU GPLv2 license. It is primarly targeted at power users, developers and any people dealing with every day computing tasks and who want to have fine-grained control on theirs graphical environment.
Qvwm - is a Windows 95/98/NT like window manager for X Window System. It allows Windows 95/98/NT users to use X Window System without hesitation and X Window System users to use Windows 95/98/NT without hesitation.
Kahakai - is a fork of the Waimea window manager, with the intent to create a language agnostic scriptable window manager, while maintaining the original features of Waimea, and extending upon them.
i3 - is an improved dynamic tiling window manager. i3 was created because wmii, the i3 developers favorite window manager at the time, didn't provide some features they wanted (Xinerama done right, for example), had some bugs, didn't progress since quite some time and wasn't easy to hack at all (source code comments/documentation completely lacking). Please be aware that i3 is primarily targeted at advanced users and developers.
GNU Screen - is a full-screen window manager that multiplexes a physical terminal between several processes, typically interactive shells. Each virtual terminal provides the functions of the DEC VT100 terminal and, in addition, several control functions from the ANSI X3.64 (ISO 6429) and ISO 2022 standards (e.g., insert/delete line and support for multiple character sets). There is a scrollback history buffer for each virtual terminal and a copy-and-paste mechanism that allows the user to move text regions between windows.
Twin - is a text-mode windowing environment: it draws and manages text windows on a text-mode display, like X11 does for graphical windows. It has a built-in window manager and terminal emulator, and can be used as server for remote clients in the same style as X11. It can display on Linux console, on X11 and inside itself.
Ratpoison - is a simple Window Manager with no fat library dependencies, no fancy graphics, no window decorations, and no rodent dependence. It is largely modelled after GNU Screen which has done wonders in the virtual terminal market. All interaction with the window manager is done through keystrokes.
BadWM - is a minimalistic window manager for the X Window System licensed under the GNU General Public License.
Window Managers for X - is a guide to window managers and desktop environments for The X Window System, as used mainly by Linux and UNIX operating systems.
