Canonical (the makers of Ubuntu) decided to remove the highly useful workspaces on default Ubuntu installations. But have no fear, this guide re-enables the workspaces within a minute or so.
It’s actually a lot easier than i thought, so ignore below and just open Settings -> Appearance and click on Behavior. Now you can re-enable workspaces with the “Enable Workspaces”-checkbox.
I’ve also updated the screenshot to better illustrate this.
First off we need to install unity-tweak-tool, either click on the link or type in the following commands in a Terminal (Ctrl + Alt + T)
sudo apt-get install unity-tweak-tool
Now open unity-tweak-tool using the Terminal:
In the window, click the “Workspace Settings”-icon (check the picture above) and flip “Workspace Switcher” to “On”.
Workspaces have now been re-enabled on your machine and it’s a persistent settings, so you don’t need to redo this if you reboot your machine.
After upgrading my installation of 12.10 Quantal Quetzal to Ubuntu 13.04 raring ringtail Unity decided to go in to hiding mode. Not sure why this happened, but resetting Unity And Compiz solved the issue for me.
Resetting Unity and Compiz is exactly what it sounds like. It will reset all customizations and configurations you’ve done to Unity and Compiz. So make sure that you backup any settings you wish to keep. Your mileage may vary.
Before resetting we need to install dconf-tools on your machine:
sudo apt-get install dconf-tools
Now run the following command to reset Unity and Compiz:
dconf reset -f /org/compiz/
All you need to do now is to logout and login and Unity should re-appear on you brand spanking fresh version of Ubuntu. Enjoy!
