On Xubuntu 18.04 I'm using hotkey right Ctrl for switching keyboard layout. And now I can't use any combinations with Ctrl+ in applications.
And for example if I use Alt for switching layout, combinations Alt+F4, Alt+Tab also doesn't work.
How to fix this?
Update. Solutions for Ubuntu Gnome and Ubuntu Mate don't work here. I can't add second hotkey for switching layout in Xubuntu/xfce.
