In this tutorial, we will see how to install Workspaces Indicator on Ubuntu 10.04/10.10/11.04. Workspaces Indicator is an alternative to default panel applet switcher, which allows users to easily switch between workspaces using a simple context menu displayed on the upper panel.
Workspaces Indicator Installation
Launch the terminal and issue these commands:
sudo add-apt-repository ppa:geod/ppa-geod
sudo apt-get update
sudo apt-get install indicator-workspaces
After launching the application, an icon with a number will be displayed on the upper panel, click it and select a workspace to open it.
To add more workspaces, select Preferences, then add as many workspaces as you want.
