I just installed fresh installation of Ubuntu 14.04 x64 and I've found that shortcut combination 'Alt + Shift' to which I used to doesn't work.
I can successfully switch keyboard layout with 'Super + Space' shortcut combination but it is inconvenient for me.
I can see shortcuts on this screen and it seems that I should set 'Alt + Shift' to 'Switch to next source' but not to 'Modifiers-only switch to next source' BUT it is impossible to assign this shortcut to that property.
I've seen some people can fix it with this 13.10 path but it doesn't work for me.
In fact when I press 'Alt + Shift' it changes current language here: but when I type it types with previously selected language.
What can I do about this? I assume there should be a way to edit some config file to assign custom shortcut or maybe there another patch for 14.04.
