I've enabled two keyboard layouts, and want to easily switch between them. In the settings menu (System Settings --> Input Devices --> Keyboard --> Advanced (tab) --> Switching to another layout) I've set Win Key+Space. But it only works one way. I've the US layout as default swedish as default, but the keyshortcut only works with US --> SV, not the other way around.

I have the same problem then I'm trying to set it manually with setxkbmap.
