(Updated Plasma Screenshot)

Plasma is the KDE workspace. Actually it is a technology that can adapt to many types of devices. Currently there are three varieties of Plasma: The Plasma Desktop environment which is the focus of the majority of our pages, the Plasma Netbook environment, and Plasma Active, the new cool environment for pads and smartphones.
A typical Plasma desktop looks like this:
The four key components of a default Plasma desktop are:
All of these default items are fully configurable and can host a wide variety of tools and content.
A "Frequent Asked Questions" for the current version of the Plasma Desktop is maintained on this page. It provides succinct answers to common questions as well as links to FAQs for older versions.
You can use Plasma as you would use the desktop of any other operating system, by accessing the application launcher, viewing the currently active programs on the taskbar, accessing icons on the system tray, and so on.
An important part of Plasma are the "widgets". Widgets are the individual units of the desktop and they include (although they are not limited to) the application menu, icons, the system tray, the clock, etc. Widgets can exist on the desktop itself, or be inserted into the panel, on the screen saver or on the dashboard among other places. Widgets exist for a large number of tasks besides usual desktop helpers, including microblogging (Twitter, identi.ca), unit conversion calculators, weather forecasts, file sharing and much more. Panels and desktops are also special kinds of widgets themselves, meant to contain other widgets.
How does that relate with desktop usage? Plasma has some new features with respect to traditional desktop usage. We have already mentioned the Plasma toolboxes: those are the way to start interacting and customizing your Plasma Desktop. By clicking on them, a menu will pop up on the screen with a variety of choices: from there you can add widgets to your panel or desktop, resize, add or remove panels, change the wallpaper and other operations.
As you may notice in the screenshot above, there are no icons placed directly on the desktop. Instead, they are placed inside a container called a "Folder View". By default, the Folder View shows the Desktop folder and allows you to drag files to it, open them, cut, copy, paste, rename files and also create new folders/files.
You can have more than one Folder View on the desktop, and they can also be placed in panels. You can set Folder View to show any folder, local or remote, you have access to. Each Folder View can be moved and resized independently to your preference.
Folder View can also be set as the default full-screen desktop background for a more traditional "icons scattered on the desktop" layout.
Panels allow you to place widgets around the edges of the screen. These collections of widgets can be configured in various ways, including making them automatically hide when not in use or aligned to certain areas of the screen.
By default, there is one panel at the bottom of the screen, but you can add more panels, move and otherwise configure the default panel and remove panels you no longer want. The widgets in all of the panels may also be adjusted to your liking.
For more information on configuring panels in Plasma Desktop and what they are capable of doing for you, visit the Plasma Panels page.
Plasma supports widgets written specifically for Plasma (also known as Plasmoids) as well as widgets from other sources such as Google Gadgets, Superkaramba and some Dashboard Widgets from Mac OSX. Additional widgets can easily be found and installed through Get Hot New Stuff.
To see the widgets that are installed on your system and ready to use open the Plasma Widget Explorer by either
To place a widget on the Desktop simply drag it from the Widget Explorer to the Desktop. To place a widget in the panel first open the Panel Toolbox and from there open the Widget Explorer (click), locate the widget you wish to add and drag it to the desired position in the Panel.
|You can not add widgets if they are locked. Open the Desktop Toolbox or the Panel Toolbox or right click on the Desktop - if you see an item labeled then select that, and then proceed to add widgets to your Desktop or your Panel.
When you are done adding widgets you might want to lock widgets again: Open a Toolbox or the Desktop context menu and click .
Widgets that are docked into a panel usually have an Options menu, while those on the desktop have the configuration options within the 'handle', the shaded area which pops up when hovering over the widget. Clicking and holding the mouse on the blank part of the handle will allow you to drag the widget to the desired position.
You have four tools on this handle. The top one is the re-sizer. Click and drag on the tool to resize the widget.
The second tool is a rotate tool. Again, click and hold the tool, while rotating to the desired angle.
The third is the wrench or spanner which allows you to configure that particular widget's settings.
Finally, the fourth tool is the "expanded view" tool and is available only on widgets that support this feature, such as the Picture Frame or Web viewers. When clicked, the Picture Frame widget will, for example, open the currently viewed in an image viewer while the Web Slice widget will open the web page in a full web browser window.
The icons shown in the screenshot have small buttons in the top right and bottom right. The small pause button in the top right prevents the activity from being included when switching through Activities using Super + Tab. It also opens up an "x" to delete the activity. To change the names of the activities, look for the small wrench in the bottom right of the icon.
A user likes web comics so they add their favorite web comics via the comics widget. The user now has a full desktop activity dedicated to their favorite web comics. Now the user is happy with the web comics, but the user now has to go to work, so the user creates an activity with the folder view widgets set to the folders of the projects the user is currently working on. After work the user goes home and works on a side project of writing romance novels. The user always gains inspiration by looking at pictures of the user's significant other. The user now creates a new Activity but now puts pictures frame widgets with pictures of the user's significant other. The user also has a folder view of the romance novel project folder. Now no matter what the user is doing the user has a custom tailored activity to match it.
Virtual desktops, the ability to have a separate sets of windows on separate desktops, can tie in with Activities. You can have a different activity on each virtual desktop. In Plasma Desktop 4.4, this can be configured by enteringand navigating to , and checking .
In Plasma Desktop 4.3, You configure this by zooming out and choosing. Then select and zoom in again.
Sometimes you might want to reload Plasma, like right after changing system language so the changes takes effect, or because of a problem with the desktop. To do that, open a terminal and run these commands:
kquitapp plasma-desktop plasma-desktop
