Keyboard shortcut to switch applications (Alt+Tab) isn't working [duplicate]

Solution 1:

Workaround until the bug is addressed:

  1. Install & run ccsm:

    sudo apt-get install compizconfig-settings-manager && ccsm

  2. Enable 'Application Switcher' under 'Window Management'

This worked for me

(note that I'm using Linux Mint 13 Maya + 'Gnome Classic' session)

Solution 2:

Launch the "keyboard" app from the Dash, and go to the "Shortcuts" tab. See if your shortcut is well configured.

It is located under the "Navigation" category and named as "Switch applications".
