In this example a Unix-like operating system is using the X windowing system and the Compiz cube plugin to decorate the KDE desktop environment.
In computing, a virtual desktop is a term used with respect to user interfaces, usually within the WIMP paradigm, to describe ways in which the virtual space of a computer's desktop environment is expanded beyond the physical limits of the screen's display area through the use of software. This compensates for a limited desktop area and can also be helpful in reducing clutter. There are two major approaches to expanding the virtual area of the screen. Switchable virtual desktops allow the user to make virtual copies of their desktop view-port and switch between them, with open windows existing on single virtual desktops. Another approach is to expand the size of a single virtual screen beyond the size of the physical viewing device. Typically, scrolling/panning a subsection of the virtual desktop into view is used to navigate an oversized virtual desktop.
Overview[edit]
As Compiz Fusion creeps closer to its first official release, its effects are well ahead of anything found in commercial operating systems. To emulate the Expose effect used in Mac OS X. The goal of this project is to bring the look and feel of Mac OS X (latest being 10.5, Leopard) on.nix GTK based systems. This document will present the procedure to install Mac4Lin pack & tweak certain things to get that almost perfect Mac OS X like desktop. NOTE: Backup all. I am using Macbook Pro with OS Lion. I have installed Ubuntu 11.10 on my VMWare Fusion 4.1.0. I am wondering is there any way to activate the compiz / 3d. I am new here and I really want to use Ubuntu 11.10 with my Mac OS X Lion VMWare Fusion. Alternatives to Compiz for Windows, Mac, Linux, BSD, Software as a Service (SaaS) and more.

Switching desktops[edit]
Switchable desktops were designed and implemented at Xerox PARC as 'Rooms' by Austin Henderson and Stuart Card in 1986[1] and (unknowingly to the authors until their publication) was conceptually similar to earlier work by Patrick Peter Chan in 1984. This work was covered by a US patent.[2]
Switchable desktops were introduced to a much larger audience by Tom LaStrange in swm (the Solbourne Window Manager, for the X Window System) in 1989. ('Virtual Desktop' was originally a trademark of Solbourne Computer.)[3] Rather than simply being placed at an x, y position on the computer's display, windows of running applications are then placed at x, y positions on a given virtual desktop “context”. They are then only accessible to the user if that particular context is enabled. A switching desktop provides a pager for the user to switch between 'contexts', or pages of screen space, only one of which can be displayed on the computer's display at any given time. Several X window managers provide switching desktops.
Oversized Desktops[edit]
Other kinds of virtual desktop environments do not offer discrete virtual screens, but instead make it possible to pan around a desktop that is larger than the available hardware is capable of displaying. This facility is sometimes referred to as panning, scrolling desktops or view-port. For example, if a graphics card has a maximum resolution that is higher than the monitor's display resolution, the virtual desktop manager may allow windows to be placed 'off the edge' of the screen. The user can then scroll to them by moving the mouse pointer to the edge of the display. The visible part of the larger virtual screen is called a viewport.
Implementation[edit]
Virtual desktop managers are available for most graphical user interfaceoperating systems and offer various features, such as placing different wallpapers for each virtual desktop and use of hotkeys or other convenient methods to allow the user to switch amongst the different screens.
Amiga[edit]
The first platform to implement multiple desktop display as a hardware feature was Amiga 1000, released in 1985. All Amigas supported multiple in-memory screens displayed concurrently via the use of the graphics co-processor, AKA the 'Copper'. The Copper was a simple processor that could wait for a screen position and write to hardware registers. Using the GUI implemented in system ROM API's, programs could transparently display multiple independent screens, from non-consecutive memory, without moving the memory. This hardware-based scrolling does not use blitting, but something more like what is sometimes called hardware panning. The video output is simply told (once, or many times) where to display (scanline) and from what screen memory address. A screen can move to any position, or display any portion, by modifying the wait, or fetch position. Typically a single byte value. The Copperlist did need to be sorted in vertical and horizontal wait position in order to function. Note: See http://www.faqs.org/faqs/amiga/books/ for a list of reference material.
Each desktop or 'screen' could have its own colour depth (number of available colours) and resolution, including use of interlacing. The display chipset ('graphics card' on a PC) could switch between these desktop modes on the fly, and during the drawing of a single screen, usually with three pixel deep line between each desktop shown on the screen. However, if one interlaced (flickering) desktop was displayed, all desktops onscreen would be similarly affected.
This also allowed the OS to seamlessly mix 'Full Screen' and Windowed 'desktop'-style applications in a single environment.
Some programs, VWorlds[4] (an astronomy simulator) being an example, used the multiple desktops feature to overlay a set of controls over the main display screen. The controls could then be dragged up and down in order to show more or less of the main display.
X Window System (Unix and Unix-like)[edit]
Almost all Unix and Unix-like systems use the X Window System to provide their windowing environment.
The X Window System is unique in that the decoration, placement, and management of windows are handled by a separate, replaceable program known as a window manager. This separation allowed third-party developers to introduce a host of different window manager features, resulting in the early development of virtual desktop capabilities in X. The first implementation of virtual desktops for Unix was vtwm in 1990. Many of today's X window managers now include virtual desktop capabilities.
Configurations range from as few as two virtual desktops to several hundred. The most popular desktop environments, GNOME and KDE, use multiple virtual desktops (two or four by default) called workspaces. Some window managers, like FVWM, offer separate 'desks' that allow the user to organize applications even further. For example, a user may have separate desks labeled 'Work' and 'Home', with the same programs running on both desks, but fulfilling different functions. Some window managers such as dwm and Sawfish support 'tagging' where applications can be configured to always launch on a particular desktop, supporting automatic organization and consistent navigation.
OS/2[edit]
IBM's personal computer OS/2 operating system included multiple desktops (up to 4 natively) in the OS/2 Warp 4 release in 1996. This functionality has also been provided by the open source XWorkplace project, with support for up to 100 virtual desktops. XWorkplace is included with the ArcaOS distribution of OS/2.[5]
Windows[edit]
Windows 10 offers virtual desktops through a system known as 'Task View'.[6][7]
Prior to Windows 10, Microsoft Windows did not implement virtual desktops natively in a user-accessible way. There are objects in the architecture of Windows known as 'desktop objects' that are used to implement separate screens for logon and the secure desktop sequence (Ctrl+Alt+Delete). There is no native and easy way for users to create their own desktops or populate them with programs.[8] However, there are many third-party (e. g. VirtuaWin, Dexpot and others) and some partially supported Microsoft products that implement virtual desktops to varying degrees of completeness.
Microsoft offers a utility called Desktops which allows users running Windows Vista or Windows Server 2008 or later operating systems to run applications on up to 4 virtual desktops. Unlike nearly all other virtual desktop solutions for Windows, this utility actually uses native 'desktop objects,' as discussed above. Because of this, it does not offer the ability to move programs between desktops, or in fact to stop using virtual desktops at all, short of logging off,[9] and Windows Aero only works on the primary desktop object.
Microsoft had previously provided a Virtual Desktop PowerToy for Windows XP, which simulates many desktops with the more common method of hiding and showing windows in groups, each group being a different desktop. However, the functionality provided is less comprehensive than that of many other virtual desktop solutions (e. g. maintain a window in a given desktop even when its application bar button flashes, etc.). As with all virtual desktop utilities that work by hiding and showing windows, application compatibility problems are common, because application developers do not expect virtual desktops to be in use on the Windows platform.
Historically, software packaged with some video card drivers provided virtual desktop functionality, such as in Nvidia's nView product (this product has been discontinued for GeForce card owners since Vista). Some of these programs provide eye-candy features similar to those available on Compiz.
Many desktop shell replacements for Windows, including LiteStep, Emerge Desktop and others, also support virtual desktops via optional modules.
Mac OS X[edit]
Despite its Unix underpinnings, Mac OS X does not use the X Window System for its GUI, and early versions had no provision for virtual desktops. Beginning with Mac OS X 10.5 Leopard in late 2007, Mac OS X has shipped with native virtual desktop support, called Spaces, which allows up to 16 virtual desktops. It allows the user to associate applications with a particular 'Space'. As of Mac OS X 10.7 Lion, this functionality has been moved into Mission Control.
Scrolling desktops were made available to Macintosh users by a 3rd party extension called Stepping Out created by Wes Boyd (the future founder of Berkeley Systems) in 1986. The code for this extension was integrated by Apple into a later version of the Mac OS, although the ability to create virtual desktops larger than the screen was removed. The code was used instead as an assist for visually impaired users to zoom into portions of the desktop and view them as larger, more easily discerned images.
BeOS[edit]
BeOS includes an implementation of virtual desktops called 'Workspaces'. Up to 32 different Workspaces are supported.

Compiz and Docky users wanting to add the slick OS X style ‘genie’ minimizing effect to their arsenal of bling should sit up straight and pay attention.
Whilst the default ‘magic lamp’ effect in Compiz is okay, it doesn’t feel anywhere near as slick as its Macintosh counterpart. Previously users could achieve a similar the window-sucking effect by users getting down and dirty with a hex editor and hack around in various files.
Compiz For Mac Os 10.13
Now, thanks to the work of a dude called Plácido, it is as easy as downloading a file, and, well, running it!
He stopped by the OMG! inbox with details of his nifty tool earlier, telling us:
“I think it´s a bit difficult to make those changes with the hex editor and all that. So I created a simple little program in C language to make it really easy to make those changes and have the MacOS like effect when minimizing with compiz and the magic lamp effect.”

You’ll find the full details in Spanish on his blog. You can view a hodge-podge Google translated version here.
If you’re still left scratching you’re head here’s what to do: –
Compiz Mac Os
- Right click on it and choose ‘properties > permissions’ and allow it to ‘execute’ as a programme by checking the relevant box
- Now open a terminal and enter: –
- sudo ./genie_compiz
- Open up CompizConfig Settings and proceed to edit the ‘MagicLamp’ effect values as per the screenshots on Placidio’s blog.
