At A Glance

A typical Plasma desktop looks like this:

KDESC Default Desktop.png

The four key components of a default Plasma desktop are:

  • The panel, sometimes referred to as "the task bar", it provides room for the application launcher, the list of windows (programs), clock and system tray;
  • The desktop, the area where widgets and icons reside;
  • The folder view, a widget that lists the content of a folder on your computer, giving you quick access to basic file management tasks;
  • The Plasma toolbox This is located at the top right of the screen as well as at end of the panel. These are used to access configuration and other options quickly and reliably.

All of these default items are fully configurable and can host a wide variety of tools and content.

The Plasma Desktop FAQ

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.

Finding your way around Plasma

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.

Folder Views

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. Visit the Folder View page to find out how to do this and much more with Folder View.


Panel Settings.png

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 long 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 Widget Explorer

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.

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.

A list of Plasma widgets with their own page can be found here, and some of our favourite widgets are discussed on the Plasma Widgets page


Plasma Activity Explorer

Use Cases

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 a 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.

Go to this blog to read a few tips on using activities.

Widget Layouts and Virtual Desktops

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 entering System Settings and navigating to Desktop -> Multiple Desktops, and checking "Different Activity for Each Desktop".

In Plasma Desktop 4.3, You configure this by zooming out and choosing "configure Plasma". Then select "use a different activity on each desktop" and zoom in again.
