How can I configure Unity?

Question

Are there any configuration options for the Unity desktop?

---

There are multiple valid answers for this question spanning over several versions of Ubuntu. For your convenience an index of each below:

• 12.04
• 11.10
• 11.04

If you're looking to configure Unity 2D, look here.

Answer 1

Ubuntu 11.04

There are two options to edit the settings. Either using the CompizConfig Settings Manager (ccsm) or the Configuration Editor (gconf-editor). I'll describe both ways.

CompizConfig Settings Manager

1. Warning: CCSM is in universe and not shipped by default for a reason, it can be flaky, so be careful in there, it can break things, if you find yourself with a broken window manager, see this question to reset your configuration.

2. Install the CompizConfig Settings Manager (CCSM).

3. Hit Alt-F2 and input about:config and hit enter.

You can now configure quite a few different settings. Like key shortcuts, the launcher behavior and appearance of the Launcher.

On the Behaviour tab you can configure:

1. The Hide Launcher sets the launchers hide behavior.

   • Never - The launcher will never hide.
   • Autohide - The launcher will hide automatically based on time.
   • Dodge Windows - The launcher will hide when a window would overlay it.
   • Dodge Active Window - The launcher will hide only when an active window would overlay it.

2. The key to show the launcher which by default is the Super key. This will also affect the key used to show the dash (if tapped) and the shortcuts shown when keeping Super pressed.

3. The key to put keyboard-focus o the launcher so you can navigate using your keyboard (default Alt + F1).

4. The key to open a Search Command dash where you can enter a command name you want to execute. (dafault Alt + F2).

5. The key to open the first panel menu (default F10).

On the Experimental tab (might change hence the name):

1. The Backlight Mode sets how the icons are back-lit.

   1. Backlight Always On - the icon back light will always be on.

   

   1. Backlight Toggles - the icon back light will be on as long as the application is running.

   

   1. Backlight Always Off - pretty much the opposite of the first option.

   

   1. The Launch Animation sets how the icons are animation.

      • None - no animation will be shown.
      • Pulse Until Running - the icon's back light will pulse till it loads up.
      • Blink - the icon's back light will blink.

   2. The Urgent Animation sets how an icon will inform you of something important.

      • None - no animation.
      • Pulse - it will pulse.
      • Wiggle - it will wiggle.

   3. The Panel Opacity sets the opacity of the panel.

   4. The Launcher icon size sets the size of the launcher in pixels.

   5. The Hide Animation sets how the launcher hide and unhide.

      • Fade on bfb and Slide - fades based on the position of your cursor in the bfb (big funny button - the one in the top left of your panel with the Ubuntu circle of friends on it) and slides.
      • Slide only - it will only slide.
      • Fade only - it will only fade.

   6. The Dash Blur sets the level of blur in the dash

      • No Blur
      • Static - snapshot of the desktop that doesn't get updated (in cases where the drivers can't handle it)
      • Realtime - Updating of things behind the dash in real time (Not implemented yet)

Configuration Editor (gconf-editor)

1. Open up the Configuration Editor by Pressing Alt + F2 and typing gconf-editor

2. Navigate to apps -> compiz-1 -> plugins -> unityshell -> screen0 -> options.

Now you can set settings described above. Clicking on an item will show a short description in the Key Documentation panel.

Configuration Editor (dconf-editor)

There are also some options you can edit using dconf-editor (needs to be installed first by installing dconf-tools at Ubuntu Software Center or by clicking here):

1. Open up the Configuration Editor by pressing Alt + F2 and typing dconf-editor

2. Navigate to Desktop -> Unity to find the first two options:

   • form-factor: The form factor chosen will affect the size of the Dash. Desktop uses a fixed sized Dash, Netbook will always maximize the Dash to screen size, Automatic decides whether to use Desktop or Netbook based on the screen resolution.
   • home-expanded: Whether the home screen of the Dash should be expanded (Expanded) or not (Not Expanded).

3. Navigate to Desktop -> Unity -> Devices

   • devices-option: Key for setting the devices that will be shown on the launcher. Never -> never show devices on the launcher, OnlyMounted -> only show devices that are mounted, Always -> also show unmounted devices.
4. Navigate to Desktop -> Unity -> Launcher
   • favorites-migration: This is a detection key for the favorite migration script to know whether the needed migration is done or not. You don't want to change that.
   • favorites: This is a list of desktop files that show up in the launcher.
5. Navigate to Desktop -> Unity -> Panel
   • systray-whitelist: List of programs that are allowed to put icons in the panel's tray area: [''] -> none , ['all'] -> all programs, or a list of program names.

Launcher & Menus (unity-preferences)

There is another option to configure how to show the launcher then it is hidden.

1. Open the Launcher & Menus configuration utility by pressing Alt + F2 and typing unity-preferences.

   

   • Pushes the left edge of the screen will make the launcher appear about one second after pushing the cursor to the left edge of the screen.

   • Touches the top left corner of the screen will make the launcher appear immediately when the cursor touches the top left corner of the screen.

2. Select the desired option.

Answer 2

Ubuntu 11.10

This answer has been written taking this as base and modifying it for Ubuntu 11.10

There are two options to edit the settings. Either using the CompizConfig Settings Manager (ccsm) or the dconf-editor.

Note that (some?) changes only appear after logging out and in again (i.e. restarting X).

CompizConfig Settings Manager

2. Install the CompizConfig Settings Manager (Click the link)

3. Hit Alt+F2 and type about:config and hit enter.

You can now configure quite a few different settings, like key shortcuts, the launcher behavior and appearance of the Launcher.

On the Behaviour tab you can configure:

1. The Reveal Mode sets from which edge the launcher will reveal.

1. The Edge Reveal Timeout sets the waiting time (in ms) before the launcher is revealed when a window is touching the edge.

On the Switcher Tab:

1. Automatically grid windows on timer in switcher: Turn this off if you want don't want to automatically expand multiple windows in alt-tab.

2. Bias alt-tab sorting to prefer windows on the current viewport: Select this if you want alt tab to prioritize the order in which applications are shows in alt-tab. Applications in your current workspace are listed first.

On the Experimental tab (might change hence the name):

1. The Backlight Mode sets how the icons are back-lit.

   1. Backlight Always On - the icon back light will always be on.

9. Show Devices sets when to show devices in the launcher.

   • Never - Devices are never shown in the launcher.
   • Only Mounted - Device that are mounted are shown in the launcher.

   • home-expanded: Whether the home screen of the Dash should be expanded (Expanded) or not (Not Expanded).

Extra tip for changing dash/launcher color

A new feature for Unity in 11.10 is the ability to change the color of the dash/launcher to match the user's current wallpaper. To take advantage of this, simply set a new wallpaper for your desktop, and the color will change automatically to match.

Note that more advanced control over the dash/launcher color (i.e., setting them to separate or arbitrary colors regardless of the wallpaper chosen) is currently not possible...at least not through an option. The dash/launcher color can actually be arbitrarily set by using an image editor to change the center pixels of your chosen wallpaper to the desired color. (See the OMG! Ubuntu article documenting this here.)

Answer 3

You can use Confity ( Download Link )

Simple and lightweight graphical user interface to configure Unity in Ubuntu 11.04 and above.

Answer 4

A new simple Unity tweaking tool, but very powerfull, is "MyUnity":

You can do a lot of thing, more than many other tools. From now, he is in italian, but I think that english translation will come sooner.

Now available in English, refer to OMG!Ubuntu article from December 11.

Answer 5

There is an unofficial Compiz plugin that allows you to move the Unity launcher to the bottom (looks out of place and ugly there in my opinion).

More information about it at: http://www.webupd8.org/2011/10/how-to-move-unity-launcher-to-bottom-of.html

Personally would wait for an official plugin for this but if you are feeling feisty...

Use at your own risk.

Answer 6

This is a place-holder answer pending 12.04-Precise Release. I will update this through this intervening periods - please drop a comment with any questions or ideas for improvement. Thanks.

Ubuntu 12.04

overview

The default configuration option installed as standard is User Interface.

There are three further unity configuration options used in this answer that can be installed:

• MyUnity
• dconf-editor
• ccsm

Note: In previous answers, the utility CCSM was extensively used as the primary configuration tool. The use of this tool is strongly not recommended and can break your desktop. In this answer, CCSM is only used where the other tools do not offer the configuration options discussed.

Note that some changes only appear after logging out and in again (i.e. restarting X).

User Interface

1. Hit the Dash and search for appearance

From the Appearance tab you can configure the:

• wallpaper
• theme
• size of the launcher icons

From the Behaviour tab you can configure the:

• how to invoke the launcher by moving the mouse (hot-spot) - either left-side of the screen or the top-left corner
• how quickly the launcher is revealed - lower the slide bar, the longer the mouse needs to be at the hot-spot to be revealed.

MyUnity

1. Hit Alt+F2 and type myunity and hit enter.

You can now configure quite a few different settings, like the launcher behavior, dash configuration, panel transparency, desktop icons and various font settings.

Answer 7

Unity is configured through compiz. Install the CompizConfig Settings Manager (ccsm) from the Software Centre, and look under the desktop section for Unity options.

Unity 2D settings can be configured with a tool available here: http://marianochavero.wordpress.com/2011/04/20/a-simple-gui-for-unity-2d-settings-ubuntu-11-04/

Answer 8

Next Ubuntu Tweak release (0.6) will include some tweaks to configure Unity :

Answer 9

Aside from the CCSM (Compiz Config Settings Manager) configurations described in another reply to this thread, you can also change what menu options appear when you right-click on an application launcher (icon) in Unity through custom launchers and so-called quicklists.

For example, you can add STOP, PLAY, PAUSE, NEXT, PREVIOUS to your Banshee icons, you can add your favorite folders to your Nautilus (file browser) icon, you can add common SSH servers to your terminal icon, etc.

To find examples and instructions of said quicklists, see another popular question: List of custom Launchers & Quicklists for Unity.
