Same problems on a Dell laptop and an HP tower after upgrading from 11.10. Have Canadian and Norwegian keyboards installed. alt+shift changes the language on the indicator, but the layout is not effectively changed. Same problem if I use the mouse to change the layout on the keyboard-indicator. Related to the following discussion: http://ubuntuforums.org/showthread.php?t=1968980. There is a temporary workaround posted: running 'sudo setxkbmap -option grp:alt_shift_toggle no,ca' after login.
