How do I add and remove the Workspace Switcher launcher from the Unity launcher?

Question

How can I remove the Workspace Switcher launcher from the Unity dock?

Answer 1

13.04

By default, the workspace-switcher is not enabled in the Launcher. This setting is toggleable via the Appearance - Behaviour tab in System Settings

Untick the option shown in the following picture to remove the workspace-switcher icon.

12.10

If you are prepared to work with just one virtual desktop (i.e. no additional workspaces) then the following will work for 12.10 and later.

gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ hsize 1
gsettings set org.compiz.core:/org/compiz/profiles/unity/plugins/core/ vsize 1

For Ubuntu 11.10 & Ubuntu2D

Edit the file /usr/share/unity-2d/launcher/Launcher.qml with your favorite text editor, ie:

sudo nano /usr/share/unity-2d/launcher/Launcher.qml

For Ubuntu 12.04 & Ubuntu2D

Edit the file /usr/share/unity-2d/shell/launcher/Launcher.qml with your favorite text editor, ie:

sudo nano /usr/share/unity-2d/shell/launcher/Launcher.qml

Locate these lines

    Component.onCompleted: {
        items.appendModel(bfbModel);
        items.appendModel(applications);
        items.appendModel(workspaces);
        items.appendModel(devices);
        shelfItems.appendModel(trashes);
    }

And change them to

    Component.onCompleted: {
        items.appendModel(bfbModel);
        items.appendModel(applications);
/*        items.appendModel(workspaces);*/
        items.appendModel(devices);
        shelfItems.appendModel(trashes);
    }

Unfortunately the desktop switcher is hard coded to unity and cannot be removed without making source code modifications.

Make sure you have the package dpkg-dev installed

sudo apt-get install dpkg-dev

To modify the code and compile it your self you need to do the following

mkdir ~/code
cd ~/code
mkdir build
cd build
apt-get source unity
cd unity*

Open plugins/unityshell/src/LauncherController.cpp with your favorite text editor, ie:

nano plugins/unityshell/src/LauncherController.cpp

Locate the lines

num_workspaces_ = WindowManager::Default()->WorkspaceCount();
if (num_workspaces_ > 1)
{
  InsertExpoAction();
}

Change them to

/*num_workspaces_ = WindowManager::Default()->WorkspaceCount();
if (num_workspaces_ > 1)
{
  InsertExpoAction();
}*/

Build the package

sudo apt-get build-dep unity
debuild -us -uc

Wait for it to finish and install when done

cd ..
sudo dpkg -i unity*.deb libunity*.deb netbook*.deb

Ubuntu 11.04/11.10 workaround (does not work in Unity 2D):

1. Install Compiz Config Settings Manager from the Ubuntu Software Center

2. Open Compiz Config Settings Manager from Dash

3. Goto General Options and Desktop Size tab

4. Change Horizontal Virtual Size to '1', the Vertical Virtual Size can be any number.

5. Restart Unity by opening Run Command (Alt-F2) and typing unity

Currently there's a handy little bug in unity that allows you to do this. Open a up a terminal and run 'gnome-panel'. Once gnome panel is running, add the 'workspace switcher' applet to the panel. Open up the workspace switcher preferences and select 1 column and 4 rows. Log out and back into unity, and viola! The workspace switcher is missing now.

Yes I know, it's a somewhat annoying way of removing it if you use workspaces, but it's the only way i know of right now..

To get the Unity launcher switcher back, simply open the gnome-panel in terminal again, and go back to a 2 X 2 grid. Logout and log back in.

1. To disable workspaces completely
   • See @fossfreedom answer http://askubuntu.com/a/211169

2. To just remove the icon but still preserve workspaces

   • Open the terminal and execute:

     gsettings get com.canonical.Unity.Launcher favorites
     

   the output will be something like,

   ['application://nautilus.desktop', 'application://chromium-browser.desktop', 'application://ubuntu-software-center.desktop', 'application://ubuntuone-installer.desktop', 'application://ubuntu-amazon-default.desktop', 'application://UbuntuOneMusiconeubuntucom.desktop', 'application://gnome-control-center.desktop', 'unity://running-apps', 'unity://expo-icon', 'unity://devices']`
   

   To remove the workspaces icon from the dock you should just take out 'unity://expo-icon' from that list. Taking it out, for this case the command should be:

   gsettings set com.canonical.Unity.Launcher favorites "['application://nautilus.desktop', 'application://chromium-browser.desktop', 'application://ubuntu-software-center.desktop', 'application://ubuntuone-installer.desktop', 'application://ubuntu-amazon-default.desktop', 'application://UbuntuOneMusiconeubuntucom.desktop', 'application://gnome-control-center.desktop', 'unity://running-apps', 'unity://devices']"`.
   

   (Don't forget the double quotes for the list on gsettings set)

Currently I'm using eight workspaces with the help of Unity Tweak Tool. I like to have multiple workspaces, but didn't like the unremovable Unity Launcher icon that much, even more because it could only resemble four workspaces while I was using eight instead.

This is now easy, thanks to an addition to Isaac Joseph's lovely Unity Revamped (also brings back dodge-windows and dodge-active-window and gives a few other options).

Add the repository with your software manager of choice or:

sudo add-apt-repository ppa:ikarosdev/unity-revamped

This is now an alternative source of unity, that'll report itself as just slightly ahead of the canonical one in version. Upgrade and you'll have this new version:

apt-fast update && apt-fast dist-upgrade

Or if you don't use apt-fast, then:

sudo apt-get update && sudo apt-get dist-upgrade

Or just use the software updater.

Log out and in, and go to ccsm. The Ubuntu Unity Plugin will now have, on the "experimental" tab an option labelled 'Show "Expo Icon" in the launcher', that's enabled by default. Disable this and the icon is gone.

Disabling the icon doesn't disable the Super+S binding, should that be your preferred way of switching workspaces.
