Keyboard shortcuts containing the command to change the keyboard layout are not forwarded to applications, what should I do?

Question

linux

keyboard shortcuts (shortcuts) containing a combination for changing the layout are not forwarded to applications.
Those. The event is not delegated from the window manager (in this case, Unity) to applications:
for example, Ctrl + Shift + I or Ctrl + Shitf + Tab when changing layouts to Ctrl + Shift.
Checked through xev - there is an event - but it is not transferred to the application.
When changing the layout change combination, the problem remains (but with other combinations, respectively) - the released Ctrl+Shift+{any other key} starts working.
The problem arose after the next update (from Ubuntu 13.04 to 13.10)
, did anyone encounter something similar and how can this be solved? (except for the rollback to 13.04)
I don’t really understand nixes. I will be grateful for help.

Answer 1

Ubuntu 13.10 broke modifier key switching. Set up switching layouts about Ctrl + Space and everything will work.
