I have installed Ubuntu Gnome 13.10 and I can't figure out why I can't make changing keyboard layout shortcut to Ctrl+Shift. I have 3 languages in my input sources.
I see in
Tweak Tool that "Key(s) to change layout" is set to Ctrl+Shift.
If I open
dconf Editor I see that in desktop->ibus->general->hotkey the
next-engine-in-menu preferences are set to ['Alt+Shift_L'].
But somehow I have figured out that input language can be changed by Ctrl+Shift+L. When I click Ctrl+Shift I can see the language changing in the top right corner, but input language stays the same. Any ideas why this can happen and how can I change it?
UPDATE: Also, I have found that changing system keyboard shortcut setting works in System Settings->Keyboard->Shortcuts->Typing->Switch to next(previous) source. But I cannot set there Ctrl+Shift or Alt+Shift setting which I want to set. The only comfortable combination I set there was Ctrl+Shift+Space. I have seen a bug on this here: Bug #1218322: Can't set keyboard layout change to alt+shift, ctrl+shift, etc.
Any suggestions on how it can be fixed?
