Toggling language with Alt+Shift doesn't work

On a recent install of 10.10 I can't toggle with Alt + Shift between USA/Isr, even though I can toggle by pressing the language icon on the tool bar.

Any suggestions?

Solution 1:

Have you checked the keyboard preferences?

Go to System --> Preferences --> Keyboard --> "Layouts" Tab --> Options

and find the option "Key(s) to change layout"

Solution 2:

if you are using Ubuntu 14,the keyboard shortcut is Super (Windows Logo) + Space bar,it will toggle between the languages.

if you have more than two languages,shortcut for the next source is Super (Windows Logo) + Space bar and for the previous source is Shift + Super (Windows Logo) + Space bar.

you can change the shortcuts using text entry setting.
