I've found on 14.10, if you enable the shortcut in CCSM and then disable it, that effectively disables it. However, I've also found each distro release re-enables this annoying shortcut, even if it's marked as disabled.

Something here isn't respecting user prefs on upgrade, and isn't correctly representing the current settings in the settings interface. -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.
