Lumina® offers a wide variety of plugins which allow the user to customize their desktop experience. Plugins are divided between context menu, desktop, and floating panel plugins.
4.2. Desktop Plugins¶
Desktop plugins adds icons or widgets for display on the main screen of
the Lumina® Desktop Environment. Click on the default start menu in the
lower left of the main desktop screen, then click
Preferences → Configure Desktop → Interface Configuration → Desktop Icons and Plugins.
This is the primary menu for configuring desktop plugins, seen in Figure 4.2.1. Click the green plus to open a Select Plugin window. The user can choose between the available plugins by opening the drop-down menu and clicking the desired plugin. Once a plugin has been selected, it will appear in the Embedded Utilities window.
The Display Desktop Folder Contents option is used to
display each item stored in
~/Desktop as an icon on the desktop.
By default, this option is selected as its box is black. De-select this
option and click Save Changes to remove the icons for the
~/Desktop from the desktop. To define a smaller area
on the desktop for displaying icons, use the Desktop Icons View
Once all the desired plugins have been added, click Save in the upper right section. The menu will automatically save and implement any changes to the desktop plugins.
There are numerous plugins in the desktop category, listed in alphabetical order.

4.3. Floating Panel Plugins¶
Panels are a completely customizable option for Lumina® users. By
default, Lumina® users have one panel stretched across the bottom of
the primary screen and one smaller pop-up panel in the top middle of the
primary screen. To adjust the default panels and add plugins, click the
start menu and navigate
Preferences → Configure Desktop → Interface Configuration → Floating Panels and Plugins.
For demonstration purposes, a simple panel centered at the top of a
secondary screen was utilized to show the various plugins listed below.
The settings for this panel are pictured in
Panel 1 is configured to the top center of Monitor 1 (plugged into DVI-I-0). To add or adjust plugins for this panel, click the green puzzle piece to open the menu seen in Figure 4.3.2.
The large field shows currently active plugins. Click the red minus or green plus buttons to add or remove plugins to the panel. Use the arrow keys to alter the display order of attached plugins. By default, plugins will populate horizontal panels from left to right, and vertical panels from top to bottom. All the plugins available for panel plugins are listed below.
4.3.1. Panel Application Launcher¶
When you select this plugin, seen in Figure 4.3.3, it will prompt to select the application to launch. This will add a shortcut for launching the selected application to the panel.
4.3.3. Audio Player (Panel)¶
The panel audio player is identical to the desktop Audio Player, except the player is on the chosen panel.
4.3.4. Battery Monitor¶
Hover over this icon (not pictured) to view the current charge status of the battery. When the charge reaches 15% or below, the low battery icon flashes intermittently. At 5% charge remaining, a low battery icon displays and a warning noise plays.
4.3.5. Desktop Bar¶
This plugin adds shortcuts to the panel for applications or files
contained within the
~/Desktop folder or favorited by the user,
seen in Figure 4.3.5. The Star
button displays applications, the folder button displays
folders, and the file button shows favorite files.
Adds a separator line to the panel to provide visual separation between plugins, highlighted in Figure 4.3.6. When adding a line plugin in the Panel Plugins Menu, be sure to use the arrow buttons in the bottom-right corner of the window to place the line entry between the plugins to be separated.
4.3.8. Show Desktop¶
This button, seen in Figure 4.3.7, immediately hides all open windows on all active monitors so only the desktop is visible. This is useful for touch screens or small devices.
4.3.11. System Dashboard¶
The System Dashboard plugin, seen in Figure 4.3.10, is a convenient shortcut to view or modify a number of basic settings. The system volume and screen brightness can be manually adjusted higher or lower, and it is possible to toggle between virtual workspaces with the left and right arrows. A Log Out button has also been added for additional convenience. If the system has a battery, its current charge will also be displayed.
Adjusting the screen brightness on a multi-monitor system alters both monitors.
4.3.12. System Tray¶
Provides an area on the panel for dockable applications, seen in Figure 4.3.11. Applications can be sent to this area on a per-application basis, but only one system tray plugin can be active at a time. By default, the active system tray will be the one on the lowest number monitor and panel. For example, when adding the system tray plugin to monitor zero, panel one and again to monitor one, panel one, only the system tray on monitor zero will be active. Disabling the system tray on monitor zero activates the tray on monitor one, automatically migrating any docked applications to the other panel.
4.3.13. Task Manager Plugin (No Groups)¶
Ensures that every window gets its own button on the panel. This plugin, seen in Figure 4.3.12, uses a large amount of space on the panel, as every window displays part of its title. This plugin is added to the default panel for Lumina®.
4.3.14. Task Manager Plugin¶
Figure 4.3.13 shows three open terminal windows grouped into one minimal panel entry with (3) displayed next to the terminal icon.
The grouping task manager displays windows in the panel as well. Its primary function is to group windows by application, saving more space on the panel. This manager also does not typically display window titles on the panel, saving additional space.
Displays the current time and date. A basic clock is added to the panel; clicking it opens the calendar, seen in Figure 4.3.14, which highlights the current date. Click the arrows in the top corners to look back or ahead in the calendar. Click Time Zone to adjust the displayed time.
