I upgraded my Ubuntu from 12.04 to 14.04 and hotkeys for switching workspaces (Ctrl + Alt + arrow keys) are not working anymore.

I checked in System Settings > Keyboard > Shortcuts to make sure that they're assigned and they are, but why they are not working? How can I fix this problem?

nope, workspaces are already enabled, just hotkeys are not working. – Modestas Andrijauskas Sep 15 '14 at 14:50

If this was an upgrade the number of workspaces should have remained the same, I believe. – Luís de Sousa Sep 15 '14 at 14:50

I found the solution myself. It seems that I needed to enable Desktop Wall plugin in Compiz; just apt-get install compizconfig-settings-manager, run ccsm and search for "wall" to find the option.

This has broken for me a couple times now in Ubuntu; most recently after going from 12.04LTS to 14.04LTS (in place upgrade).

  • System Settings... (gear at top of screen)
  • Appearance
  • Behavior Tab
  • Check box for Enable workspaces

Screen grab of configuration setting for workspaces:

Run these two commands: 

sudo apt-get install ubuntu-desktop
sudo apt-get install unity

Reboot your system

And after than try Ctrl + Alt + arrow keys. You will able to switch between workspaces.

unfortunately doesn't work for me :( I'm able to switch between 1 and 2 while cannot go to 3 and 4 via 1 and 2. In other words I'm able to switch horizontal between 1 and 2, 3 and 4 while I'm not able to switch between 1 and 3, 2 and 4 :( – Hesam Oct 2 '15 at 23:56
